After a bronchoscopy, what is the most critical assessment before allowing the patient to drink water?
Return of the cough and gag reflex
Why are elderly patients at a significantly higher risk for aspiration?
Weakened cough reflex
When is the best time to obtain a sputum specimen for the most accurate results?
First thing upon awakening.
You walk into a room and the cardiac monitor shows Ventricular Tachycardia. What is your very first action?
Check for a pulse!
A patient in the early stage of hypovolemic shock has a BP of 118/72, but their heart rate has increased from 80 to 112 bpm. Why is the blood pressure still within normal limits?
The body is in the Compensatory Stage (catecholamine release causes vasoconstriction and increased HR to maintain CO).
A patient with COPD is admitted with increased shortness of breath. Their ABG shows: pH 7.32, pCO2 52, and HCO3 28. Which component indicates the body has already started to compensate?
The HCO3 (Bicarbonate); it is elevated (normal 22-26) as the kidneys retain base to buffer the respiratory acid.
You note several Premature Ventricular Contractions (PVCs) on a patient’s telemetry. Which electrolyte imbalance should the LPN check for first in the laboratory results?
Hypokalemia (Low Potassium) or Hypomagnesemia.
DAILY DOUBLE: You've hit the Daily Double! You can wager up to your current total score. Here is your question:
List the three components of Virchow’s Triad that lead to a DVT/Pulmonary Embolism."
1. Venous Stasis (immobility)
2. Hypercoagulability (thick blood/clotting issues)
3. Endothelial Damage (vessel injury).
DOUBLE JEOPARDY:
Following a Pneumonectomy (removal of an entire lung), the LPN knows the patient should be positioned on which side to allow the remaining lung to expand fully?
The operative side (the "bad" side) to keep the "good" lung up and free to expand.
Why is a patient with a fractured femur at high risk for a Pulmonary Embolism (PE)?
Immobility (leading to DVT) or the risk of a Fat Embolism from the bone marrow.
A patient is returning from a Transesophageal Echocardiogram (TEE). The LPN knows the patient must remain NPO until what occurs?
The gag reflex returns (due to the local anesthetic used to numb the throat).
A patient's pulse oximetry reads 88% on room air. The patient is slightly confused but breathing at 18/min. What are the LPN’s first independent actions as long as standing orders are in place?
Apply oxygen (usually via nasal cannula at 2L) and elevate the head of the bed.
During the "Compensation" stage of shock, the body releases catecholamines. What two physiological changes should the nurse expect to see in the vital signs?
Increased heart rate and vasoconstriction (potentially maintaining BP)
A patient with a bowel obstruction has been vomiting for 8 hours. Their ABG shows pH 7.50, pCO2 42, and HCO3 33. What is the interpretation?
Metabolic Alkalosis
A patient’s monitor shows a rapid, chaotic rhythm with no discernible P waves or QRS complexes. The patient is pulseless. What is the immediate priority action?
Initiate CPR. (Ventricular Fibrillation)
A patient with a chest tube has 150mL of drainage in the last hour. What is the nurse's next action?
Report it immediately (threshold is >100ml/hr).
30 minutes before a provider removes a chest tube, what nursing intervention should be performed?

To check for a pneumothorax.
DOUBLE JEOPARDY:
A patient with a Permanent Pacemaker is going home. Name one medical procedure they can never have.
They can never have an MRI.
An LPN is caring for a patient with a spinal cord injury who is suddenly exhibiting bradycardia, hypotension, and warm, dry skin. Which specific type of shock does this indicate, and why is the skin warm instead of cool?
Neurogenic Shock; loss of sympathetic tone causes massive vasodilation, preventing the usual "cold/clammy" vasoconstriction.
An anxious patient is hyperventilating. Their ABG is: pH 7.48, pCO2 30, HCO3 24. What is the interpretation, and what is a simple nursing intervention to help "recycle" their CO2?
Respiratory Alkalosis; have the patient breathe into a paper bag (rebreathing CO2).
A patient is in Ventricular Tachycardia but is awake and talking. The nurse knows the provider will likely order this procedure, which is a "timed" shock synchronized with the R-wave.
Synchronized Cardioversion.
An LPN is assisting with a Thoracentesis. What is the proper positioning for the patient during this procedure to ensure the provider can access the pleural space?
Sitting upright, leaning forward over a bedside table (orthopneic position).
Following a Rhinoplasty, the patient is frequently swallowing. What complication does the LPN suspect?
Hemorrhage (bleeding) down the back of the throat.
List three factors that place a patient at "High Risk" for a respiratory infection.
(Any 3) Age >65, living in extended care, chronic respiratory/cardiac/renal disease, diabetes, or compromised immune system.
Which cardiac lab is the most specific marker for myocardial injury?
Troponin
A patient with a tracheostomy is restless, has crackles in the lungs, and an inability to cough out secretions. What does this indicate is needed?
Suctioning
A patient in the ICU has a "Low Pressure" alarm sounding on their ventilator. Upon assessment, you note the patient is increasingly restless and has absent breath sounds on the left. What complication is likely occurring?
Pneumothorax (causing a leak/disconnection in the system pressure)
A patient has a pH of 7.36, pCO2 40, and HCO3 26. The nurse knows that if the pH is between 7.35 and 7.45, the condition is considered this.
Fully Compensated
A patient in Sinus Bradycardia (HR 48) is dizzy and has a BP of 88/50. Which three classes of drugs might be responsible? NAME AT LEAST TWO
Digitalis glycosides, Beta-blockers, and Calcium channel blockers.
DOUBLE JEOPARDY:
For a patient on a ventilator, the Low Pressure Alarm sounds. The LPN finds the patient has self-extubated (pulled the tube out). What is the immediate priority action?
Use a Bag-Valve-Mask (Ambu-bag) with 100% Oxygen to manually ventilate the patient.
A patient is 2 hours post-op from a Thoracotomy. The LPN notes that "tidaling" (fluctuation of water with breathing) has stopped in the water-seal chamber. If the lung is not yet fully re-expanded, what does this most likely indicate?
An obstruction or kink in the chest tube/tubing.
Explain the relationship between Anaphylactic Shock and airway patency. What two physiological changes are happening in the respiratory system?
Bronchospasm (constriction of airways) and Laryngeal Edema (swelling of the throat).
A patient is scheduled for a Stress Test using Persantine (a chemical stressor). What specific substance must the patient avoid for 24 hours prior to the test to ensure accuracy?
Caffeine (it interferes with the medication's effect on the heart).
You are caring for a patient with a "Do Not Resuscitate" (DNR) order who enters Ventricular Fibrillation. The family is in the room crying and asking you to "do something." What is the appropriate LPN response?
Provide comfort and support to the family while explaining that the patient's wishes are being honored; do not initiate CPR or defibrillation.
A patient in the progressive stage of shock is receiving aggressive IV fluid resuscitation. The LPN notes the patient has developed crackles in the lung bases, a bounding pulse, and a CVP (Central Venous Pressure) reading that has risen significantly above normal. What specific complication of shock treatment is occurring, and what is the immediate priority nursing action?
Fluid Volume Overload (or Pulmonary Edema); The priority is to slow the IV rate and notify the provider (or prepare to administer diuretics).
DOUBLE JEOPARDY:
A patient is in Respiratory Acidosis. As the LPN, you know the primary goal is to improve ventilation. Identify two nursing interventions that physically help the patient "blow off" more CO2.
Incentive Spirometry, Pursed-lip breathing, or turning/positioning (High-Fowler's).
An LPN is monitoring a patient who suddenly develops a rhythm characterized by a "sawtooth" pattern of P-waves and an atrial rate of 300 bpm. While the patient is currently stable, what is the primary clinical risk associated with this rhythm if it persists, and what medication class is typically used to prevent this complication?
Atrial Flutter; The risk is thrombus/clot formation (leading to stroke); It is treated with anticoagulants (like Warfarin or Heparin).
When managing a patient with a chest tube connected to a water-seal drainage system, the LPN observes constant, vigorous bubbling in the water-seal chamber. This differs from the expected "tidaling." What does this finding indicate, and what is the nurse's first assessment step to troubleshoot the source?
It indicates a system leak; The nurse should cross-clamp the tube briefly near the insertion site to see if the bubbling stops (determining if the leak is in the patient or the tubing).
Six hours after a Total Laryngectomy, the patient’s tracheostomy tube becomes obstructed by a thick mucus plug and the patient becomes cyanotic. If the LPN is unable to clear the airway with suctioning and the patient's respiratory distress increases, what is the most critical emergency action?
Use a hemostat to keep the stoma open (or insert an emergency replacement tube) and call for the Rapid Response Team/Provider immediately.
DOUBLE JEOPARDY:
Explain the relationship between Diabetes and Myocardial Infarction (MI) presentation. Why might a diabetic patient NOT feel the classic "chest pain"?
Diabetic Neuropathy (nerve damage) can mask the pain, leading to a "Silent MI."
A patient is scheduled for a Cardiac Catheterization using contrast dye. The LPN reviews the morning labs and finds a Creatinine level of 2.4 mg/dL and a BUN of 40 mg/dL. Why must the nurse hold the procedure and notify the provider immediately?
These labs indicate impaired renal function (Kidney Failure/Insufficiency). The contrast dye is nephrotoxic and could cause acute kidney injury if the patient cannot excrete it.
You are caring for four patients on a Med-Surg unit. Which patient must the LPN see first:
A post-op patient with a pulse of 110 and a BP of 100/60.
A patient with a chest tube that has 40mL of drainage in the last 2 hours.
A patient with an ABG of pH 7.34 and pCO2 of 46.
A patient who just returned from a Bronchoscopy and is complaining of a "sore throat."
Patient 1. While the others have minor issues, Patient 1 shows signs of early compensated shock (tachycardia and borderline low BP) and requires immediate assessment for hemorrhage or dehydration.
A patient in Septic Shock is receiving large volumes of crystalloid fluids and potent vasopressors. The LPN notes the patient’s fingers and toes are becoming dusky and cold, and the platelet count is rapidly dropping while small purple spots (petechiae) appear on the trunk. What secondary, life-threatening coagulation disorder is likely occurring?
Disseminated Intravascular Coagulation (DIC). This is a paradox where the body uses up all clotting factors causing both systemic micro-clots (causing the dusky digits) and simultaneous bleeding.
A patient with chronic renal failure has a pH of 7.28 and an HCO3 of 18. The pCO2 is 32. In this scenario, the lungs are attempting to compensate for the metabolic acidosis. What specific respiratory pattern would the LPN expect to see, and how does this pattern physically help the acid-base balance?
Kussmaul’s Respirations. These are deep, rapid, labored breaths that maximize the "blow-off" of Carbon Dioxide (an acid) to attempt to bring the pH back toward a normal range.
A patient with a history of heart failure is taking Digoxin. They report seeing "yellow-green halos" around lights and have an apical pulse of 42. What is the most dangerous cardiac rhythm abnormality associated with this drug toxicity, and what electrolyte imbalance significantly increases the risk of this happening?
Third-Degree (Complete) Heart Block or severe Bradycardia; Hypokalemia (Low Potassium) increases the risk of Digoxin toxicity.
During the management of a patient with Acute Respiratory Distress Syndrome (ARDS), the provider orders the patient to be placed in the Prone position. What is the physiological rationale for placing a patient on their stomach to improve oxygenation?
Proning shifts perfusion to the anterior (front) portion of the lungs, which are typically less damaged by fluid/atelectasis in ARDS, thereby improving ventilation-perfusion (V/Q) matching and recruiting collapsed alveoli in the posterior lungs.
Following a Thyroidectomy, the LPN notes the patient has developed a high-pitched, harsh sound upon inspiration (stridor) and is complaining of tingling in their fingertips (paresthesia). What do these specific findings suggest regarding a common surgical complication?
Accidental removal or damage to the Parathyroid glands, leading to Hypocalcemia. The tingling is a sign of neuromuscular irritability, and the stridor indicates laryngeal nerve damage or tetany.
A patient is diagnosed with a Tension Pneumothorax. Beyond the absence of breath sounds, identify the "late" clinical sign that indicates the heart and great vessels are being physically pushed toward the unaffected side, and explain why this causes a rapid drop in Blood Pressure.
Mediastinal Shift (or Tracheal Deviation). The pressure shifts the heart and compresses the Vena Cava, which drastically reduces Venous Return, leading to a sudden drop in cardiac output and obstructive shock.
DOUBLE JEOPARDY:
A patient’s BNP (B-type Natriuretic Peptide) is 1,200 pg/mL. What specific diagnosis does this "stretch" hormone confirm?
Heart Failure.
A patient with a pulmonary embolism is on Heparin IV. Which lab value must the nurse closely monitor to ensure the dose is therapeutic?
Partial Thromboplastin Time (PTT).
DOUBLE JEOPARDY:
A patient in shock is prescribed a Vasopressor (like Norepinephrine). What is the absolute "must-check" assessment before and during administration to ensure the drug isn't causing peripheral tissue necrosis?
Check IV site patency (ensure it's in a large vein/central line) and neurovascular checks of the extremities.
A patient with Type 1 Diabetes is admitted with a blood glucose of 650 mg/dL and Kussmaul’s respirations. Their ABG results are: pH 7.21, pCO2 28, and HCO3 14. Identify the acid-base imbalance and explain why the pCO2 is lower than the normal range of 35-45.
Metabolic Acidosis with Partial Respiratory Compensation. The pCO2 is low because the lungs are "blowing off" CO2 (an acid) via hyperventilation to try and raise the pH.
On an EKG, this wave represents atrial depolarization and contraction.
The P wave.
While monitoring a patient on a ventilator, the "High Pressure" alarm sounds. List two potential causes the LPN should immediately assess for.
(Any 2) Patient biting the tube, secretions in the airway (needs suctioning), tubing kinks, or the patient fighting the ventilator (asynchrony).
Following a cardiac catheterization via the femoral artery, what are two priority nursing interventions for the affected extremity?
Monitor pulses, color, and warmth (neurovascular checks) and keep the leg straight.
Explain the physiological "vicious cycle" of Cardiogenic Shock. Specifically, how does the body’s compensatory mechanism of systemic vasoconstriction (increased SVR) actually end up worsening the failure of the heart's "pump" function?
Vasoconstriction increases afterload (the resistance the heart must pump against). A failing heart cannot overcome this increased resistance, which further decreases cardiac output and increases myocardial oxygen demand, leading to further heart failure.
A patient is scheduled for a Ventilation-Perfusion (V/Q) Scan to rule out a Pulmonary Embolism. What is the most critical question the LPN must ask a female patient of child-bearing age before this specific test, and why?
"Is there any possibility you are pregnant?" Because the V/Q scan involves the administration of radioactive isotopes (radio-nucleotides) which are teratogenic to a fetus.
An LPN is caring for a patient on a ventilator who has developed Subcutaneous Emphysema around the neck and upper chest. While palpating the "rice-krispy" feeling under the skin, the nurse notices the patient’s neck veins are distended and their heart sounds are muffled (distant). What is this triad of symptoms called, and what emergency procedure must the nurse prepare for?
Beck’s Triad (indicating Cardiac Tamponade); the nurse must prepare for an emergency Pericardiocentesis (aspiration of fluid from the pericardial sac).
This interval on the EKG represents the time it takes for an electrical impulse to move from the atria to the AV node.
The PR interval
