66 year old man with sudden onset of respiratory distress. He is conscious but unable to follow verbal commands. His breathing is severely labored and his oxygen saturation is at 80%. What should you do?
Assist ventilations with bag mask device.
Diaphragm and intercostal muscles relax during
Inhalation
Nitroglycerin is usually administered by an EMT this way
sublingually
Cardiac tampenade will most likely cause what type of shock?
Obstructive
Harsh, high-pitched inspiratory sounds are characteristic of:
Stridor
After assisting a 65 year old female with prescribed nitroglycerin, she complains of dizziness and her systolic blood pressure drops to 30 mm Hg. She remains conscious and her breathing is adequate. What should you do?
Place her in supine position
Low blood oxygen levels influence the
Hypoxic drive
Why is aspirin beneficial to patients suspected of having a heart attack?
Hypovolemic shock caused by severe burns is the result of a loss of
plasma
The jaw-thrust maneuver is used to open the airway of patients with suspected:
cervical spine injuries
A 56-year-old male is found semiconscious by his wife. Your assessment reveals that his respirations are rapid and shallow, his pulse is rapid and irregular, and his blood pressure is low. The patient’s wife states that he complained of left arm pain and nausea the day before, but would not allow her to call 9-1-1. The MOST likely cause of this patient’s present condition is:
acute myocardial infarction
Adult respiratory rate
12-20 breaths min
When administering supplemental oxygen to a hypoxemic patient with a chronic lung disease, you should:
Adjust the flow rate accordingly until you see symptom improvement, but be prepared to assist his or her ventilations.
Name the signs and symptoms of decompensated shock
Declining blood pressure, loss of consciousness, cyanotic, dilated pupils, absent radial pulse
You are dispatched to an apartment complex where a 21-year-old female has apparently overdosed on several narcotic medications. She is semiconscious and has slow, shallow respirations. You should:
Insert a nasopharyngeal airway and begin assisted ventilation.
A 59-year-old male with a history of emphysema complains of an acute worsening of his dyspnea and pleuritic chest pain following a forceful cough. Your assessment reveals that he has a barrel-shaped chest, unilaterally diminished breath sounds, and tachycardia. What is the MOST likely cause of this patient’s condition?
spontaneous pneumothorax
Nasopharyngeal airway
Contraindications of CPAP
Inability to sit up, closed head injury, facial anomalies, unconscious, inability to speak/protect airway, nausea/vomiting, respiratory arrest, hypotension, cardiogenic shock, penetrating chest trauma, suspected pneumothorax, GI bleed/surgery
Of the following conditions which should not make you suspect shock - anaphylaxis, spinal injury, ischemic stroke, severe infection?
ischemic stroke
The primary waste product of aerobic metabolism
Carbon dioxide.
A 62-year-old man with a history of congestive heart failure presents with severe respiratory distress and with an oxygen saturation of 82%. When you auscultate his lungs, you hear widespread rales. He is conscious and alert, is able to follow simple commands, and can only speak in two- to three-word sentences at a time. You should:
Apply a CPAP device, monitor his blood pressure, and observe him for signs of improvement or deterioration.
