Question 1: A 45-year-old male is found unresponsive with agonal respirations and
a palpable carotid pulse of 40 beats per minute. What is the MOST appropriate
immediate action for the EMT-I?
A. Start high-flow oxygen via non-rebreather mask
B. Perform synchronized cardioversion at 100 joules
C. Insert an oropharyngeal airway and assist ventilations with a bag-valve-mask
D. Administer atropine 0.5 mg intravenously
CORRECT ANSWER: C. Insert an oropharyngeal airway and assist ventilations with
a bag-valve-mask
Rationale: The patient has agonal respirations, which are ineffective for gas exchange.
Airway management and assisted ventilation are the immediate priorities to prevent
hypoxia and cardiac arrest. Atropine is for symptomatic bradycardia, but airway and
breathing take precedence.
Question 2: Which of the following findings is MOST indicative of a tension
pneumothorax in a trauma patient?
A. Diminished breath sounds bilaterally
B. Hypotension with distended neck veins
C. Pulse oximetry reading of 92% on room air
D. Bruising over the left lateral chest wall
CORRECT ANSWER: B. Hypotension with distended neck veins
Rationale: Tension pneumothorax causes hypotension due to decreased venous return
(obstructive shock) and distended neck veins (jugular venous distension) from
increased intrathoracic pressure. Diminished breath sounds are unilateral, not bilateral.
Question 3: A patient with chest pain is administered sublingual nitroglycerin.
Which of the following is an absolute contraindication to its administration?
A. Systolic blood pressure less than 90 mmHg
B. Heart rate greater than 100 beats per minute
C. History of a myocardial infarction
D. Use of a beta-blocker medication
,CORRECT ANSWER: A. Systolic blood pressure less than 90 mmHg
Rationale: Nitroglycerin is a potent vasodilator that lowers blood pressure. It is
contraindicated in hypotension (SBP < 90 mmHg) because it can precipitate
cardiovascular collapse. It is also contraindicated with phosphodiesterase inhibitors
(e.g., sildenafil).
Question 4: What is the primary purpose of administering aspirin to a patient
experiencing an acute coronary syndrome?
A. To relieve severe chest pain immediately
B. To dissolve the occlusive coronary thrombus
C. To prevent further platelet aggregation
D. To reduce myocardial oxygen demand
CORRECT ANSWER: C. To prevent further platelet aggregation
Rationale: Aspirin inhibits cyclooxygenase and reduces platelet aggregation, preventing
the enlargement of existing thrombi. It does not dissolve clots (thrombolytics do that) or
act as an analgesic.
Question 5: In the management of a patient with a severe allergic reaction, which
medication should the EMT-I administer FIRST?
A. Albuterol via nebulizer
B. Diphenhydramine intramuscularly
C. Epinephrine 1:1000 intramuscularly
D. Methylprednisolone intravenously
CORRECT ANSWER: C. Epinephrine 1:1000 intramuscularly
Rationale: Epinephrine is the first-line treatment for anaphylaxis. It reverses
bronchospasm and vasodilation, counteracting the life-threatening effects of histamine
release. Antihistamines and corticosteroids are secondary agents.
Question 6: An EMT-I is preparing to suction a patient's airway. What is the
maximum recommended suction time for an adult patient to avoid hypoxia?
A. 5 seconds
B. 10 seconds
C. 15 seconds
D. 20 seconds
CORRECT ANSWER: C. 15 seconds
Rationale: Suctioning should not exceed 15 seconds in adults (10 seconds in children)
to prevent hypoxia. Prolonged suctioning removes oxygen from the airway and can
induce bradycardia via vagal stimulation.
Question 7: Which of the following respiratory patterns is characterized by
progressively deeper breaths followed by a period of apnea?
,A. Cheyne-Stokes respiration
B. Kussmaul respiration
C. Biot's respiration
D. Apneustic respiration
CORRECT ANSWER: A. Cheyne-Stokes respiration
Rationale: Cheyne-Stokes respirations are characterized by a cyclic pattern of gradual
increases and decreases in tidal volume followed by apnea. It is often associated with
heart failure, stroke, or increased intracranial pressure.
Question 8: A patient presents with a sudden onset of sharp chest pain, dyspnea,
and hemoptysis following a long car ride. What condition should the EMT-I suspect
MOST?
A. Spontaneous pneumothorax
B. Acute myocardial infarction
C. Pulmonary embolism
D. Esophageal rupture
CORRECT ANSWER: C. Pulmonary embolism
Rationale: The classic triad of sudden chest pain, dyspnea, and hemoptysis with a risk
factor for venous stasis (prolonged travel) is highly suggestive of a pulmonary embolism.
The clot usually originates from deep vein thrombosis in the lower extremities.
Question 9: How should the EMT-I calculate the estimated blood loss in a patient
with a fractured femur?
A. 500 mL
B. 750 mL
C. 1000 mL
D. 1500 mL
CORRECT ANSWER: D. 1500 mL
Rationale: A closed femur fracture can result in up to 1500 mL of blood loss into the
thigh compartment, which is significant and can lead to hypovolemic shock. Pelvic
fractures can lose even more.
Question 10: What is the correct ratio of compressions to ventilations for a two-
rescuer adult CPR performed by EMTs?
A. 15:2
B. 30:2
C. 30:1
D. 15:1
CORRECT ANSWER: B. 30:2
, Rationale: According to AHA guidelines, the compression-to-ventilation ratio for adults
is 30:2 for all rescuers, regardless of the number of rescuers (except for neonates). This
maximizes coronary perfusion pressure.
Question 11: The EMT-I is assessing a patient with a heat emergency. Which finding
indicates heat stroke rather than heat exhaustion?
A. Profuse sweating
B. Core temperature of 101°F
C. Muscle cramps
D. Altered mental status
CORRECT ANSWER: D. Altered mental status
Rationale: Heat stroke is a life-threatening condition defined by hyperthermia (>104°F)
and central nervous system dysfunction (altered mental status, seizures, or coma).
Heat exhaustion may present with normal mentation.
Question 12: Which of the following veins is the FIRST choice for IV access in a
prehospital setting?
A. Basilic vein
B. Cephalic vein
C. External jugular vein
D. Femoral vein
CORRECT ANSWER: B. Cephalic vein
Rationale: The cephalic vein in the antecubital fossa is the preferred site due to its
accessibility and size. It is easily visualized and palpated, and it remains stable during
movement.
Question 13: A patient is hyperventilating secondary to anxiety. What is the primary
physiological consequence of this condition?
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis
CORRECT ANSWER: B. Respiratory alkalosis
Rationale: Hyperventilation causes excessive exhalation of carbon dioxide (CO2),
leading to a decrease in plasma CO2 and subsequent respiratory alkalosis (increased
pH). This can cause peripheral vasoconstriction and paresthesia.
Question 14: Which of the following is a sign of cardiac tamponade?
A. Narrowing pulse pressure
B. Widening pulse pressure
