The nurse in charge formulates a nursing diagnosis of Activity intolerance related to inadequate oxygenation and dyspnea for a client with chronic bronchitis. To minimize this problem, the nurse instructs the client to avoid conditions that increase oxygen demands. Such conditions include:


  •  A. Drinking more than 1,500 ml of fluid daily.
  •  B. Being overweight.
  •  C. Eating a high-protein snack at bedtime.
  •  D. Eating more than three large meals a day.

What is B?

Conditions that increase oxygen demands include obesity, smoking, exposure to temperature extremes, and stress. Patients with COPD can experience hypoxia during increased activity and may need oxygenation to avoid hypoxemia which puts them at risk for exacerbations of the condition.

  • Option A: A client with chronic bronchitis should drink at least 2,000 ml of fluid daily to thin mucus secretions; restricting fluid intake may be harmful. Assess the patient’s respiratory response to the activity which includes monitoring of respiratory rate and depth, oxygen saturation, and use of accessory muscles for respiration.
  • Option C: The nurse should encourage the client to eat a high-protein snack at bedtime because protein digestion produces an amino acid with sedating effects that may ease insomnia associated with chronic bronchitis. Adequate energy reserves are needed during activity.
  • Option D: Eating more than three large meals a day may cause fullness, making breathing uncomfortable and difficult; however, it doesn’t increase oxygen demands. To help maintain adequate nutritional intake, the client with chronic bronchitis should eat small, frequent meals (up to six a day).

The nurse in charge is teaching a client with emphysema how to perform pursed-lip breathing. The client asks the nurse to explain the purpose of this breathing technique. Which explanation should the nurse provide?


  •  A. It helps prevent early airway collapse.
  •  B. It increases inspiratory muscle strength.
  •  C. It decreases use of accessory breathing muscles.
  •  D. It prolongs the inspiratory phase of respiration.

What is A?

Pursed-lip breathing helps prevent early airway collapse. Learning this technique helps the client control respiration during periods of excitement, anxiety, exercise, and respiratory distress. The positive pressure created opposes the forces exerted on the airways from the flow of exhalation. As a result, pursed-lip breathing helps support breathing by the opening of the airways during exhalation and increasing excretion of volatile acids in the form of carbon dioxide preventing or relieving hypercapnia.

  • Option B: To increase inspiratory muscle strength and endurance, the client may need to learn inspiratory resistive breathing. Inspiratory resistive breathing is a clinically relevant model encountered in many disease states such as upper airway obstruction, chronic obstructive pulmonary disease (COPD) exacerbations and asthma attacks. Resistive breathing increases the plasma level of proinflammatory cytokines.
  • Option C: To decrease accessory muscle use and thus reduce the work of breathing, the client may need to learn diaphragmatic (abdominal) breathing. Diaphragmatic breathing is a type of breathing exercise that helps strengthen the diaphragm, an important muscle that helps breathe as it represents 80% of breathing. This breathing exercise is also sometimes called( belly breathing or abdominal breathing).
  • Option D: In pursed-lip breathing, the client mimics a normal inspiratory-expiratory (I:E) ratio of 1:2. (A client with emphysema may have an I:E ratio as high as 1:4.). The expiratory phase of respiration is going to prolong when compared to inspiration to expiration ratio in normal breathing.

A nurse teaches a client about the use of a respiratory inhaler. Which action by the client indicated a need for further teaching?


  •  A. Removes the cap and shakes the inhaler well before use.
  •  B. Press the canister down with your finger as he breathes in.
  •  C. Inhales the mist and quickly exhales.
  •  D. Waits 1 to 2 minutes between puffs if more than one puff has been prescribed.

What is C?

Take the inhaler out of the mouth. If the client can, he should hold his breath as he slowly counts to 10. This lets the medicine reach deep into the lungs. The client should be instructed to hold his or her breath at least 10 to 15 seconds before exhaling the mist.

  • Option A: If the client has not used the inhaler in a while, he may need to prime it. See the instructions that came with the inhaler for when and how to do this. Shake the inhaler hard 10 to 15 times before each use.
  • Option B: Hold the inhaler with the mouthpiece down. Place lips around the mouthpiece so that the mouth forms a tight seal. As the client starts to slowly breathe in through the mouth, press down on the inhaler one time.
  • Option D: If using inhaled, quick-relief medicine (beta-agonists), wait about 1 minute before taking the next puff. You do not need to wait a minute between puffs for other medicines.

A community health nurse is conducting an educational session with community members regarding TB. The nurse tells the group that one of the first symptoms associated with TB is:

  • A. A bloody, productive cough
  •  B. A cough with the expectoration of mucoid sputum
  •  C. Chest pain
  •  D. Dyspnea

What is B?

One of the first pulmonary symptoms includes a slight cough with the expectoration of mucoid sputum. A chronic cough, hemoptysis, weight loss, low-grade fever, and night sweats are some of the most common physical findings in pulmonary tuberculosis. Other options are late symptoms and signify cavitation and extensive lung involvement.

  • Option A: As the bacterium begins multiplying in the body and destroying tissue, it causes symptoms such as a bad, persistent cough, fatigue/loss of energy, weight loss, loss of appetite, chills, fever, drenching night sweats, chest pain, and coughing up or spitting up bright red blood, a symptom that occurs when the blood vessels inside the lungs become eroded and begin to bleed.
  • Option C: Pulmonary or systemic dissemination of the tubercles may be seen in active disease, and this may manifest as miliary tuberculosis characterized by millet-shaped lesions on chest x-ray. Disseminated tuberculosis may also be seen in the spine, the central nervous system, or the bowel.
  • Option D: Secondary tuberculosis differs in clinical presentation from the primary progressive disease. In secondary disease, the tissue reaction and hypersensitivity is more severe, and patients usually form cavities in the upper portion of the lungs.

A 79-year-old client is admitted with pneumonia. Which nursing diagnosis should take priority?


  •  A. Acute pain related to lung expansion secondary to lung infection.
  •  B. Risk for imbalanced fluid volume related to increased insensible fluid losses secondary to fever.
  •  C. Anxiety related to dyspnea and chest pain.
  •  D. Ineffective airway clearance related to retained secretions.

What is D?

Pneumonia is an acute infection of the lung parenchyma. The inflammatory reaction may cause an outpouring of exudate into the alveolar spaces, leading to an ineffective airway clearance related to retained secretions. This diagnosis is related to excessive secretions and ineffective cough or nonproductive coughing. Inflammation and increased secretions in pneumonia make it difficult to maintain a patent airway.

An oxygenated delivery system is prescribed for a client with COPD to deliver a precise oxygen concentration. Which of the following types of oxygen delivery systems would the nurse anticipate to be prescribed?


  •  A. Venturi mask
  •  B. Aerosol mask
  •  C. Face tent
  •  D. Tracheostomy collar

What is A?

The venturi mask delivers the most accurate oxygen concentration. The Venturi mask is the best oxygen delivery system for the client with chronic airflow limitation because it delivers a precise oxygen concentration. An air-entrainment (also known as venturi) mask can provide a pre-set oxygen to the patient using jet mixing. As the percent of inspired oxygen increases using such a mask, the air-to-oxygen ratio decreases, causing the maximum concentration of oxygen provided by an air-entrainment mask to be around 40%.The face tent, the aerosol mask, and the tracheostomy collar are also high-flow oxygen delivery systems but most often are used to administer high humidity.

  • Option B: A mask used for the therapeutic administration of a nebulized solution, humidity, or high airflow with oxygen enrichment. It has a large-bore inlet and an exhalation port. When the required concentration needs to change during the oxygen therapy treatment pathway, the adult aerosol mask, with a choice of 6 venturis or a multi venturi mask kit, offers a convenient and cost-effective option to meet the individual patient’s requirements. The aerosol mask can be used with a nebulizer or 22mm corrugated tubing for combined oxygen therapy and humidification.
  • Option C: Face tents are used to provide a controlled concentration of oxygen and increase moisture for patients who have facial burns or a broken nose, or who are claustrophobic. It is difficult to achieve high levels of oxygenation with this mask.
  • Option D: One is to use a tracheostomy collar, which is placed over a breathing tube in a tracheotomy incision in the throat, and through which humidified oxygen is given. The other is to reduce the pressure support supplied via the ventilator.
200

A nurse is caring for a client with emphysema. The client is receiving oxygen. The nurse assesses the oxygen flow rate to ensure that it does not exceed:


  •  A. 1 L/min
  •  B. 2 L/min
  •  C. 6 L/min
  •  D. 10 L/min

What is B?

Correct Answer: B. 2 L/min

One to 3 L/min of oxygen by nasal cannula may be required to raise PaO2 to 60 to 80 mm Hg. However, oxygen is used cautiously and should not exceed 2 L/min. Because of the long-standing hypercapnia, the respiratory drive is triggered by low oxygen levels rather than increased carbon dioxide levels, as is the case in a normal respiratory system. Supplemental oxygen can successfully reach the alveoli in these lungs, which prevents this vasoconstriction and thereby increases perfusion and improves gas exchange, thus resulting in improvement of hypoxemia.

  • Option A: Routine supplemental oxygen does not improve the quality of life or clinical outcomes in stable patients. Continuous long-term, i.e., longer than 15 hours of supplemental oxygen is recommended in patients with COPD with PaO2 less than 55 mmHg (or oxygen saturation less than 88%) or PaO2 less than 59 mm Hg in case of cor pulmonale.
  • Option C: Oxygen therapy has shown to increase the survival of these patients with severe resting hypoxemia. For those who desaturate with exercise, intermittent oxygen will help. The goal is to maintain oxygen saturation greater than 90%.
  • Option D: Excessive correction of hypoxia in a patient with longstanding COPD can sometimes lead to hypercapnia. This is due to the loss of compensatory vasoconstriction with an ineffective gas exchange as there is a loss of hypoxic drive for ventilation. Also, increased oxyhemoglobin decreases the uptake of carbon dioxide due to the Haldane effect.
200

The nurse would anticipate which of the following ABG results in a client experiencing a prolonged, severe asthma attack?


 A. Decreased PaCO2, increased PaO2, and decreased pH.

 B. Increased PaCO2, decreased PaO2, and decreased pH.

 C. Increased PaCO2, increased PaO2, and increased pH.

 D. Decreased PaCO2, decreased PaO2, and increased pH

What is B?

As the severe asthma attack worsens, the client becomes fatigued and alveolar hypotension develops. This leads to carbon dioxide retention and hypoxemia. The client develops respiratory acidosis. Therefore, the PaCO2 level increases, the PaO2 level decreases, and the pH decreases, indicating acidosis.

  • Option A: Respiratory acidosis is a very common acid-base disturbance in acute severe asthma and is widely considered to be an ominous finding. Its early recognition and treatment are important and decisive for the final outcome, as it can lead to respiratory failure and arrest if prolonged.
  • Option C: Hypercapnia in asthma, in addition to the severity of the disease, is also associated with the therapeutic administration of oxygen. Thus, in patients with severe asthma exacerbation, a significant increase (?4 mmHg) in transcutaneous PCO2 (PtCO2) was observed in a higher proportion in those receiving high oxygen mixtures (>8 L/min), compared to those who received titrated oxygen (to achieve oxygen saturation of 93–95%)
  • Option D: Lee et al. noted that PaCO2 was significantly higher and the arterial blood pH lower in asthmatics who died, and delays in providing mechanical ventilation led to worse outcomes. Another mechanism implicates the Haldane effect, in which oxygen displaces the CO2 dissociation curve to the right, increasing PaCO2, which cannot be normalized as patients with severe COPD are unable to increase ventilation.
200

A client who is HIV+ has had a PPD skin test. The nurse notes a 7-mm area of induration at the site of the skin test. The nurse interprets the results as:


  •  A. Positive
  •  B. Negative
  •  C. Inconclusive
  •  D. The need for repeat testing.

What is A. Positive?

The client with HIV+ status is considered to have positive results on PPD skin test with an area greater than 5-mm of induration. The client with HIV is immunosuppressed, making a smaller area of induration positive for this type of client. If the PPD is reddened and raised 10mm or more, it’s considered positive according to the CDC. If the infection risk is very high, the PPD test need not be repeated. The positive PPD test is usually followed by TB symptom assessment, physical exam, and chest radiograph.

  • Option B: If the patient is at a high risk of developing an active infection, a repeat test is recommended after an initial negative test to rule out the possibility of missing a case. However, a decision is made based on the risk factors.
  • Option C: Inconclusive isn’t a term used to describe results of a PPD test. It is a time-sensitive test. Tests that are read late are not accurate as they tend to under-estimate the size of the skin reaction. Therefore, the reliability of the test is compromised, and the results are doubtful.
  • Option D: To avoid this, repeat testing is recommended if the reaction is not read on time. The second test can be administered as soon as possible. However, if repeated, the test should preferably be performed within 7 days of the initial test to avoid boosting effect.
200

A client with pneumonia has a temperature of 102.6*F (39.2*C), is diaphoretic, and has a productive cough. The nurse should include which of the following measures in the plan of care?


  •  A. Position changes q4h.
  •  B. Nasotracheal suctioning to clear secretions.
  •  C. Frequent linen changes.
  •  D. Frequent offering of a bedpan.

What is C, frequent linen changes?

Frequent linen changes are appropriate for this client because of diaphoresis. Diaphoresis produces general discomfort. The client should be kept dry to promote comfort. Adjust and monitor environmental factors like room temperature and bed linens as indicated.

  • Option A: Position changes need to be done every 2 hours. Room temperature may be accustomed to near normal body temperature and blankets and linens may be adjusted as indicated to regulate temperature of the patient.
  • Option B: Nasotracheal suctioning is not indicated with the client’s productive cough. Suctioning can cause increased hypoxemia; hyper oxygenate before, during, and after suctioning. Suction as indicated: frequent coughing, adventitious breath sounds, desaturation related to airway secretions.
  • Option D: Frequent offering of a bedpan is not indicated by the data provided in this scenario. Assist with self-care activities as necessary. Provide for progressive increase in activities during the recovery phase. and demand. Minimizes exhaustion and helps balance oxygen supply and demand.

A nurse is caring for a client hospitalized with acute exacerbation of COPD. Which of the following would the nurse expect to note on assessment of this client?


  •  A. Increased oxygen saturation with exercise.
  •  B. Hypocapnia
  •  C. A hyperinflated chest on x-ray film.
  •  D. A widened diaphragm noted on chest x-ray film.

What is C?

Clinical manifestations of COPD include hypoxemia, hypercapnia, dyspnea on exertion and at rest, oxygen desaturation with exercise, and the use of accessory muscles of respiration. Chest x-ray films reveal a hyperinflated chest and a flattened diaphragm as the disease is advanced. The inflammatory response and obstruction of the airways cause a decrease in the forced expiratory volume (FEV1) and tissue destruction leads to airflow limitation and impaired gas exchange. Hyperinflation of the lungs is often seen on imaging studies and occurs due to air trapping from airway collapse during exhalation.

  • Option A: Patients may have acute respiratory failure and physical findings of hypoxemia and hypercapnia. Arterial blood gas analysis, chest imaging, and pulse oximetry are indicated. A 6-minute walk test is commonly performed to assess the submaximal functional capacity of a patient. This test is performed indoors on a flat and straight surface. The length of the hallway is usually 100 feet and the test measures the distance the patient walks over a period of 6 minutes.
  • Option B: The inability to fully exhale also causes elevations in carbon dioxide (CO2) levels. As the disease progresses, impairment of gas exchange is often seen. The reduction in ventilation or increase in physiologic dead space leads to CO2 retention. Pulmonary hypertension may occur due to diffuse vasoconstriction from hypoxemia.
  • Option D: Radiographic imaging includes a chest x-ray and computed tomography (CT). Chest x-rays may show hyperinflation, flattening of the diaphragm, and increased anterior-posterior diameter. In cases of chronic bronchitis, bronchial wall thickening may be present.
300

A client with emphysema should receive only 1 to 3 L/minute of oxygen if needed, or he may lose his hypoxic drive. Which of the following statements is correct about hypoxic drive?


  •  A. The client doesn’t notice he needs to breathe.
  •  B. The client breathes only when his oxygen levels climb above a certain point.
  •  C. The client breathes only when his oxygen levels dip below a certain point.
  •  D. The client breathes only when his carbon dioxide level dips below a certain point.

What is C?

Clients with emphysema breathe when their oxygen levels drop to a certain level; this is known as the hypoxic drive. In the meantime, his carbon dioxide levels continue to climb, and the client will pass out, leading to a respiratory arrest. The hypoxic drive theory then goes on to say that if the healthcare provider gives these patients too much oxygen they blunt their hypoxic drive. As their chemoreceptors are already tolerant of high levels of carbon dioxide, and therefore they have also lost that drive, their respirations will begin to slow causing a further rise in carbon dioxide levels, and a consequent acidosis.

  • Option A: They don’t take a breath when their levels of carbon dioxide are higher than normal, as do those with healthy respiratory physiology. COPD patients tend to have chronically elevated levels of carbon dioxide due to the nature of their illness. The theory goes then that because of this chronically elevated level of carbon dioxide in the chemoreceptors become tolerant of these high levels and therefore the carbon dioxide ceases to be that person’s drive to breathe. What therefore drives them to breathe is the hypoxic drive or the lower levels of oxygen.
  • Option B: If too much oxygen is given, the client has little stimulus to take another breath. The peripheral chemoreceptors are sensitive to the levels of oxygen in the body. They will send a signal to breathe when the partial pressure of oxygen begins to fall. This is referred to as the hypoxic drive but this drive has a much more minor role in breathing.
  • Option D: The central chemoreceptors monitor carbon dioxide levels in the body. When those carbon dioxide levels are high a signal is sent to speed up the drive to breathe to blow off the excess carbon dioxide. So the levels of carbon dioxide dictate how fast we will breathe.
300

A client with acute asthma is prescribed short-term corticosteroid therapy. What is the rationale for the use of steroids in clients with asthma?


  •  A. Corticosteroids promote bronchodilation.
  •  B. Corticosteroids act as an expectorant.
  •  C. Corticosteroids have an anti-inflammatory effect.
  •  D. Corticosteroids prevent development of respiratory infections.

What is C?

Corticosteroids have an anti-inflammatory effect and act to decrease edema in the bronchial airways and decrease mucus secretion. At a physiologic level, steroids reduce airway inflammation and mucus production and potentiate beta-agonist activity in smooth muscles and reduce beta-agonists tachyphylaxis in patients with severe asthma. Corticosteroids do not have a bronchodilator effect, act as expectorants, or prevent respiratory infections.

  • Option A: Short-acting inhaled beta-agonists are the drug of the first choice in acute asthma. Albuterol is preferred over metaproterenol in that class because of its higher beta 2 selectivities and longer duration of action. The dose-response curve and duration of action of these medications are adversely affected by a combination of patient factors, including pre existing bronchoconstriction, airway inflammation, mucus plugging, poor patient effort, and coordination.
  • Option B: Anticholinergics have a variable response in acute exacerbation with a somewhat underwhelming bronchodilatory role. However, they can be useful in patients with bronchospasm induced by beta-blockade or severe underlying obstructive disease with FEV1 less than 25% of predicted.
  • Option D: Graham et al. conducted a randomized double-blinded trial and demonstrated no difference in improvement in symptom score, spirometry, or length of hospitalization with routine use of antibiotics in status asthmaticus. That does not mean that patients with clinical signs of infection should not be treated with antimicrobials, or due diligence should not be pursued in obtaining respiratory culture specimens early on.
300

A nurse is caring for a client diagnosed with TB. Which assessment, if made by the nurse, would not be consistent with the usual clinical presentation of TB and may indicate the development of a concurrent problem?


  •  A. Non Productive or productive cough
  •  B. Anorexia and weight loss
  •  C. Chills and night sweats
  •  D. High-grade fever

What is D. a high grade fever?

The client with TB usually experiences cough (non-productive or productive), fatigue, anorexia, weight loss, dyspnea, hemoptysis, chest discomfort or pain, chills and sweats (which may occur at night), and a low-grade fever. Clients with TB typically have low-grade fevers, not higher than 102*F. A chronic cough, hemoptysis, weight loss, low-grade fever, and night sweats are some of the most common physical findings in pulmonary tuberculosis.

  • Option A: In pulmonary tuberculosis, the most commonly reported symptom is a chronic cough. Cough most of the time is productive, sometimes mixed with blood. Physical examination depends on the organs involved. In the case of pulmonary TB, a patient can have crepitations, and bronchial breath sounds, especially over the upper lobes or affected area indicating cavity or consolidation.
  • Option B: Constitutional symptoms like fever, weight loss, lymphadenopathy, and night sweats are commonly reported. Extrapulmonary tuberculosis can affect any organ and can have a varied presentation.
  • Option C: A chronic cough, hemoptysis, weight loss, low-grade fever, and night sweats are some of the most common physical findings in pulmonary tuberculosis. Secondary tuberculosis differs in clinical presentation from the primary progressive disease
300

The cyanosis that accompanies bacterial pneumonia is primarily caused by which of the following?


  •  A. Decreased cardiac output.
  •  B. Pleural effusion.
  •  C. Inadequate peripheral circulation.
  •  D. Decreased oxygenation of the blood.

What is D, decreased oxygenation of the blood?

A client with pneumonia has less lung surface available for the diffusion of gases because of the inflammatory pulmonary response that creates lung exudate and results in reduced oxygenation of the blood. The client becomes cyanotic because blood is not adequately oxygenated in the lungs before it enters the peripheral circulation. It is evident that the cyanosis of pneumonia patients is due to the incomplete saturation of venous blood with oxygen in the lungs, and that the various shades of blue observed in the distal parts are caused by an admixture of reduced hemoglobin and oxyhemoglobin in the superficial capillaries.

  • Option A: With expansion of blood volume in the acute phase of pneumonia, all patients showed an increase in cardiac output, a decrease in arteriovenous oxygen difference, and a decrease in peripheral vascular resistance; however, the percentage change in the hypodynamic patients was not as great as occurred in the patients with normal hemodynamics nor as great as occurred when restudied in convalescence.
  • Option B: Pleural effusions are common in patients who develop pneumonia. At least 40-60% of patients with bacterial pneumonia will develop a pleural effusion of varying severity. Today, these parapneumonic effusions are not common because of prompt antibiotic therapy.
  • Option C: The inadequate response to pneumonia is most consistent with depressed myocardial function, but the possibility of decreased intravascular volume as a contributory factor could not be excluded. The arteriovenous oxygen difference was used to assess the adequacy of the circulation to meet peripheral tissue perfusion, and a spectrum of arteriovenous oxygen differences was noted.

A male client admitted to an acute care facility with pneumonia is receiving supplemental oxygen, 2 L/minute via nasal cannula. The client’s history includes chronic obstructive pulmonary disease (COPD) and coronary artery disease. Because of these history findings, the nurse closely monitors the oxygen flow and the client’s respiratory status. Which complication may arise if the client receives a high oxygen concentration?


  •  A. Apnea
  •  B. Anginal pain
  •  C. Respiratory alkalosis
  •  D. Metabolic acidosis

What is A?

Hypoxia is the main breathing stimulus for a client with COPD. Excessive oxygen administration may lead to apnea by removing that stimulus. During apnea, there is no movement of the muscles of inhalation, and the volume of the lungs initially remains unchanged. Depending on how blocked the airways are, there may or may not be a flow of gas between the lungs and the environment.

  • Option B: Anginal pain results from a reduced myocardial oxygen supply. A client with COPD may have anginal pain from generalized vasoconstriction secondary to hypoxia; however, administering oxygen at any concentration dilates blood vessels, easing anginal pain.
  • Option C: Respiratory alkalosis results from alveolar hyperventilation, not excessive oxygen administration. In a client with COPD, high oxygen concentrations decrease the ventilatory drive, leading to respiratory acidosis, not alkalosis.
  • Option D: High oxygen concentrations don’t cause metabolic acidosis. Determining the type of metabolic acidosis can help clinicians narrow down the cause of the disturbance. Acidemia refers to a pH less than the normal range of 7.35 to 7.45. In addition, metabolic acidosis requires a bicarbonate value less than 24 mEq/L. Further classification of metabolic acidosis is based on the presence or absence of an anion gap, or concentration of unmeasured serum anions.
400

Exercise has which of the following effects on clients with asthma, chronic bronchitis, and emphysema?


  •  A. It enhances cardiovascular fitness.
  •  B. It improves respiratory muscle strength.
  •  C. It reduces the number of acute attacks.
  •  D. It worsens respiratory function and is discouraged.

What is A?

Exercise can improve cardiovascular fitness and help the client tolerate periods of hypoxia better, perhaps reducing the risk of heart attack. People with long-term lung conditions can help improve their symptoms through regular exercise. It can be tempting to avoid exercise because one may think it will make them breathless, but if the client does less activity he becomes less fit, and daily activities will become even harder.

  • Option B: Most exercise has little effect on respiratory muscle strength, and these clients can’t tolerate the type of exercise necessary to do this. Intermittent exercises can help deal with shortness of breath. In this case, the client alternates brief exercise, lasting 1–2 minutes, with moments of rest (or slower exercise). This is called interval training.
  • Option C: Exercise won’t reduce the number of acute attacks. Having asthma should not restrict the ability to exercise or be physically active. If the client feels uncomfortable during or after exercise, he should ask his doctor to investigate whether the management of his condition could be improved. In fact, many athletes have asthma and are able to compete at the highest level when their condition is well-controlled.
  • Option D: In some instances, exercise may be contraindicated, and the client should check with his physician before starting any exercise program. It is best to ask the guidance of a doctor or physiotherapist before one begins exercising, to ensure that the exercise plans are in line with the body’s capacity and are safe. All exercise programs must be built up over time to allow the body to adapt.
400

The nurse is teaching the client how to use a metered-dose inhaler (MDI) to administer a Corticosteroid drug. Which of the following client actions indicates that he is using the MDI correctly? Select all that apply.


  •  A. The inhaler is held upright.
  •  B. Head is tilted down while inhaling the medication.
  •  C. Client waits 5 minutes between puffs.
  •  D. Mouth is rinsed with water following administration.
  •  E. Client lies supine for 15 minutes following administration.

What is A and D?

Inhaled respiratory medications are often taken by using a device called a metered-dose inhaler, or MDI. The MDI is a pressurized canister of medicine in a plastic holder with a mouthpiece. When sprayed, it gives a reliable, consistent dose of medication.

  • Option A: Remove the cap and hold the inhaler upright. Each inhaler consists of a small canister of medicine connected to a mouthpiece. The canister is pressurized. As the client presses down on the inhaler, it releases a mist of medicine. The client breathes that mist into the lungs. It’s important to use the inhaler correctly.
  • Option B: Tilt the head back slightly and breathe out all the way. Keep the chin up and the inhaler upright (not aimed at the roof of the mouth or the tongue).
  • Option C: Repeat puffs as directed by the doctor. Wait 1 minute before taking the second puff. A delay of 10–20 minutes between successive doses of the bronchodilator drug has been suggested in order to let the first act to improve the penetration and effect of the second dose, but again the evidence that this works is inconclusive. Many patients may forget to take a second dose with such a long interval.
  • Option D: Some inhalers (steroid) also recommend rinsing the mouth out with water and gargling with water (spit out the water) after use. If using this inhaler for a corticosteroid preventer medication, with or without a spacer, rinse the mouth with water and spit after inhaling the last dose to reduce the risk of side-effects
  • Option E: The client does not have to be in the supine position after administration. Proper instruction by a trained person with a placebo aerosol is essential to teach the correct inhaler technique. This should be followed subsequently by regular checks to locate any faults that may develop. Inevitably, some patients will be unable to use an MDI, and for them, spacer attachments, or dry powder inhalers are preferable since they place fewer demands on patients’ skill. Even these devices, however, must be used properly to achieve a satisfactory effect.
400

The nurse should include which of the following instructions when developing a teaching plan for clients receiving INH and rifampin for treatment for TB?


  •  A. Take the medication with antacids.
  •  B. Double the dosage if a drug dose is forgotten.
  •  C. Increase intake of dairy products.
  •  D. Limit alcohol intake.

What is D?

INH and rifampin are hepatotoxic drugs. Clients should be warned to limit intake of alcohol during drug therapy. Liver function tests should be monitored routinely as rifampin, isoniazid, pyrazinamide, and ethambutol all may exert hepatotoxic effects. CBC also requires regular monitoring for patients taking rifampin, as it can cause thrombocytopenia and neutropenia.

  • Option A: Both drugs should be taken on an empty stomach. If antacids are needed for GI distress, they should be taken 1 hour before or 2 hours after these drugs are administered. Rifampin also exerts its effects by inducing cytochrome P450(CYP450), which may cause unwanted drug interactions of medications that are metabolized by the CYP450 system and decrease their clinical efficacy.
  • Option B: Clients should not double the dosage of these drugs because of their potential toxicity. Isoniazid can cause pyridoxine deficiency that may lead to peripheral neuropathy in patients. All first-line antitubercular medications, rifampin, isoniazid, pyrazinamide, and ethambutol can exert hepatotoxic effects. A continual rise in liver functions test should prompt discontinuation of treatment.
  • Option C: Clients taking INH should avoid foods that are rich in tyramine, such as cheese and dairy products, or they may develop hypertension. All first-line antitubercular medications, rifampin, isoniazid, pyrazinamide, and ethambutol can exert hepatotoxic effects. A continual rise in liver functions test should prompt discontinuation of treatment.
400

A client with pneumonia has a temperature ranging between 101° and 102°F and periods of diaphoresis. Based on this information, which of the following nursing interventions would be a priority?


  •  A. Maintain complete bed rest.
  •  B. Administer oxygen therapy.
  •  C. Provide frequent linen changes.
  •  D. Provide fluid intake of 3 L/day.

What is D?

A fluid intake of at least 3 L/day should be provided to replace any fluid loss occurring as a result of the fever and diaphoresis; this is a high-priority intervention. Force fluids to at least 3000 mL/day or as individually appropriate. Meets basic fluid needs, reducing risk of dehydration and to mobilize secretions, and promote expectoration.

  • Option A: Provide a quiet environment and limit visitors during acute phase as indicated. Encourage use of stress management and diversional activities as appropriate. Reduces stress and excess stimulation, promoting rest. Assist the patient to assume a comfortable position for rest and sleep.
  • Option B: The purpose of oxygen therapy is to maintain PaO2 above 60 mmHg. Oxygen is administered by the method that provides appropriate delivery within the patient’s tolerance. Note: Patients with underlying chronic lung diseases should be given oxygen cautiously.
  • Option C: Adjust and monitor environmental factors like room temperature and bed linens as indicated. Room temperature may be accustomed to near normal body temperature and blankets and linens may be adjusted as indicated to regulate temperature of the patient.

At 11 p.m., a male client is admitted to the emergency department. He has a respiratory rate of 44 breaths/minute. He’s anxious, and wheezes are audible. The client is immediately given oxygen by face mask and methylprednisolone (Depo-medrol) I.V. At 11:30 p.m., the client’s arterial blood oxygen saturation is 86% and he’s still wheezing. The nurse should plan to administer:


  •  A. alprazolam (Xanax)
  •  B. propranolol (Inderal)
  •  C. Morphine
  •  D. albuterol (Proventil)

What is D?

The client is hypoxemic because of bronchoconstriction as evidenced by wheezes and a subnormal arterial oxygen saturation level. The client’s greatest need is bronchodilation, which can be accomplished by administering bronchodilators. Albuterol is a beta2 adrenergic agonist, which causes dilation of the bronchioles. It’s given by nebulization or metered-dose inhalation and may be given as often as every 30 to 60 minutes until relief is accomplished.

  • Option A: Alprazolam is an anxiolytic and central nervous system depressant, which could suppress the client’s breathing. Alprazolam, known by various trade names, is the most commonly prescribed psychotropic medication in the United States. Alprazolam is frequently prescribed to manage panic and anxiety disorders.
  • Option B: Propranolol is contraindicated in a client who’s wheezing because it’s a beta2 adrenergic antagonist. Propranolol can be used to ameliorate the sympathetic response in angina, tachyarrhythmias, prevention of acute ischemic attacks, migraine prophylaxis, and restless leg syndrome. Propranolol can be used in almost all cases if the desired result is to slow contractility and decrease a patient’s heart rate.
  • Option C: Morphine is a respiratory center depressant and is contraindicated in this situation. Morphine can decrease the heart rate, blood pressure, and venous return. Morphine can also stimulate local histamine-mediated processes. In theory, the combination of these can reduce myocardial oxygen demand.

It’s highly recommended that clients with asthma, chronic bronchitis, and emphysema have Pneumovax and flu vaccinations for which of the following reasons?


  •  A. All clients are recommended to have these vaccines.
  •  B. These vaccines produce bronchodilation and improve oxygenation.
  •  C. These vaccines help reduce the tachypnea these clients experience.
  •  D. Respiratory infections can cause severe hypoxia and possibly death in these clients.

What is D?

It’s highly recommended that clients with respiratory disorders be given vaccines to protect against respiratory infection. Infections can cause these clients to need intubation and mechanical ventilation, and it may be difficult to wean these clients from the ventilator. Another pneumococcal vaccine, PPSV23, is indicated in the United States for all adults 65 years of age and older, as well as younger patients with conditions that increase the risk for developing pneumococcal pneumonia or invasive pneumococcal disease. Conditions that would indicate PPSV23 in patients younger than 65 years of age are as follows: chronic heart disease excluding hypertension, chronic lung disease including asthma, diabetes mellitus, cerebrospinal fluid leak, cochlear implant, alcohol use disorder, chronic liver disease, cigarette smoking, hemoglobinopathy (including sickle cell disease), etc.

  • Option A: Recommendations are that all patients who received PPSV23 before the age of 65 years be revaccinated at age 65 unless the vaccine is given less than ten years before the patient turns 65 years old, in which case patients should be revaccinated ten years following the first dose. Recommendations are that patients with functional or anatomic asplenia or immunocompromised individuals receive repeat doses of the vaccination every ten years after the first dose.
  • Option B: The vaccines have no effect on bronchodilation or respiratory care. Both vaccines promote active immunization against the serotypes of the conjugate and capsular polysaccharides contained in the formulation of the vaccine. Immunity develops approximately 2 to 3 weeks after vaccination and lasts for five years. In children and the elderly, re-immunization may be necessary sooner.
  • Option C: Studies done on animals have not shown fetal adverse effects or increased risk to the fetus. It is unknown if the vaccine is excreted with breast milk. Caution is necessary when administering this vaccine to breastfeeding women. There is no overdose risk with the administration of the vaccine.

The client with asthma should be taught which of the following is one of the most common precipitating factors of an acute asthma attack?


  •  A. Occupational exposure to toxins.
  •  B. Viral respiratory infections.
  •  C. Exposure to cigarette smoke.
  •  D. Exercising in cold temperatures.

What is B?

The most common precipitator of asthma attacks is viral respiratory infection. Clients with asthma should avoid people who have the flu or a cold and should get yearly flu vaccinations. Asthma is a condition of acute, fully reversible airway inflammation, often following exposure to an environmental trigger. The pathological process begins with the inhalation of an irritant (e.g., cold air) or an allergen (e.g., pollen), which then, due to bronchial hypersensitivity, leads to airway inflammation and an increase in mucus production. This leads to a significant increase in airway resistance, which is most pronounced on expiration.

  • Option A: Environmental exposure to toxins or heavy particulate matter can trigger asthma attacks; however, far fewer asthmatics are exposed to such toxins than are exposed to viruses. Asthma comprises a range of diseases and has a variety of heterogeneous phenotypes. The recognized factors that are associated with asthma are a genetic predisposition, specifically a personal or family history of atopy (propensity to allergy, usually seen as eczema, hay fever, and asthma).
  • Option C: Cigarette smoke can also trigger asthma attacks, but to a lesser extent than viral respiratory infections. Asthma also is associated with exposure to tobacco smoke and other inflammatory gases or particulate matter.
  • Option D: Some asthmatic attacks are triggered by exercising in cold weather. The overall etiology is complex and still not fully understood, especially when it comes to being able to say which children with pediatric asthma will carry on to have asthma as adults (up to 40% of children have a wheeze, only 1% of adults have asthma), but it is agreed that it is a multifactorial pathology, influenced by both genetics and environmental exposure.

The nurse is teaching a client who has been diagnosed with TB how to avoid spreading the disease to family members. Which statement(s) by the client indicate(s) that he has understood the nurse’s instructions? Select all that apply.


  •  A. “I will need to dispose of my old clothing when I return home.”
  •  B. “I should always cover my mouth and nose when sneezing.”
  •  C. “It is important that I isolate myself from family when possible.”
  •  D. “I should use paper tissues to cough in and dispose of them properly.”
  •  E. “I can use regular plates and utensils whenever I eat.”

What is B, C, D, and E?

Review pathology of disease (active and inactive phases; dissemination of infection through bronchi to adjacent tissues or via bloodstream and/or lymphatic system) and potential spread of infection via airborne droplet during coughing, sneezing, spitting, talking, laughing, singing.

  • Option A: Identify others at risk like household members, close associates, and friends. Those exposed may require a course of drug therapy to prevent spread or development of infection.
  • Option B: Instruct patient to cough or sneeze and expectorate into tissue and to refrain from spitting. Initial therapy of uncomplicated pulmonary disease usually includes four drugs, e.g., four primary drugs or combination of primary and secondary drugs.
  • Option C: Review necessity of infection control measures. Put in temporary respiratory isolation if indicated. May help the patient understand the need for protecting others while acknowledging the patient’s sense of isolation and social stigma associated with communicable diseases.
  • Option D: Review proper disposal of tissue and good hand washing techniques. Encourage return demonstration. Compliance with multidrug regimens for prolonged periods is difficult, so directly observed therapy (DOT) should be considered.
  • Option E: Contagious period may last only 2–3 days after initiation of chemotherapy, but in presence of cavitation or moderately advanced disease, risk of spread of infection may continue up to 3 months.

Which of the following would be priority assessment data to gather from a client who has been diagnosed with pneumonia? Select all that apply.


  •  A. Auscultation of breath sounds.
  •  B. Auscultation of bowel sounds.
  •  C. Presence of chest pain.
  •  D. Presence of peripheral edema.
  •  E. Color of nail beds.

What is A, C, and E?

A respiratory assessment, which includes auscultating breath sounds and assessing the color of the nail beds, is a priority for clients with pneumonia. Assessing for the presence of chest pain is also an important respiratory assessment as chest pain can interfere with the client’s ability to breathe deeply. Auscultating bowel sounds and assessing for peripheral edema may be appropriate assessments, but these are not priority assessments for the patient with pneumonia.

  • Option A: The movement of air generates normal breath sounds through the large and small airways. Normal breath sounds have a frequency of approximately 100 Hz. The absence of breath sounds should prompt the health care provider to consider shallow breath, abnormal anatomy or pathologic entities such as airway obstruction, bulla, hyperinflation, pneumothorax, pleural effusion or thickening, and obesity.
  • Option B: When bowel sounds are not present, one should listen for a full 3 minutes before determining that bowel sounds are, in fact, absent. Auscultation for abdominal bruits is the next phase of abdominal examination. Bruits are “swishing” sounds heard over major arteries during systole or, less commonly, systole and diastole. The area over the aorta, both renal arteries. and the iliac arteries should be examined carefully for bruits.
  • Option C: In the face of a history of chest discomfort, ask the patient to point to the area(s) of greatest discomfort. Palpate the area with increasing firmness in an attempt to elicit tenderness and to assess if this maneuver reproduces the patient’s symptoms. Pay particular attention to the costochondral junctions in patients reporting anterior chest pain to evaluate the possibility of costochondritis.
  • Option D: The detailed physical exam can help immensely to differentiate systemic causes such as CHF (common findings are jugular venous distension, dyspnea, bilateral crackles, history of heart disease), liver disease (jaundice, ascites, history of hepatitis, and alcohol use disorder), renal disease (proteinuria, oliguria, history of uncontrolled diabetes and hypertension), thyroid disease (fatigue, anemia, weight gain).
  • Option E: Active observation skills are used to search for the use of pursed lips during expiration, the activity and development of the sternocleidomastoid muscles, the use of other accessory muscles of ventilation, the presence of shoulder girdle fixation in relation to the use of these accessory muscles, the flaring of the nasal alae, the presence of jugular venous distention, the degree of comfort, and, as discussed in previous chapters, the presence of cyanosis and clubbing.
