QUESTION 1
A 58-year-old male presents with acute onset of severe chest pain
radiating to his left arm, accompanied by diaphoresis and nausea. His
vital signs are BP 90/60, HR 110, RR 22, SpO2 94% on room air. After
ensuring scene safety and standard precautions, which of the following
is the MOST appropriate initial action?
A) Administer high-flow oxygen via non-rebreather mask.
B) Obtain a 12-lead ECG immediately.
C) Administer sublingual nitroglycerin.
D) Perform a focused history including the OPQRST mnemonic.
Answer: D
Explanation: The initial action in any medical assessment, after scene
safety and BSI, is to perform a primary assessment and then obtain a
focused history. While obtaining a 12-lead ECG and administering
medications are critical, they follow the initial history and physical
examination. High-flow oxygen is only indicated if the patient is hypoxic
(SpO2 < 94%) or shows signs of respiratory distress; this patient's SpO2

is 94%, which is borderline but does not immediately mandate high-flow
oxygen. The OPQRST mnemonic is essential for understanding the
nature of the chest pain before any interventions are performed, as it
guides differential diagnosis and treatment.
QUESTION 2
During the primary assessment of an unresponsive 45-year-old female,
you note she is apneic and pulseless. What is the immediate next step
after confirming cardiac arrest?
A) Attach the automated external defibrillator (AED).
B) Begin chest compressions at a rate of 100-120 per minute.
C) Provide two rescue breaths.
D) Open the airway using the head-tilt chin-lift maneuver.
Answer: B
Explanation: According to current AHA guidelines, the immediate action
for a patient in cardiac arrest is to begin high-quality chest
compressions. The sequence is C-A-B (Compressions, Airway, Breathing).
After confirming unresponsiveness and apnea, the rescuer should
activate emergency response and begin chest compressions. The AED
should be applied as soon as it is available, but compressions are the
priority. The head-tilt chin-lift is part of the airway management but
follows the initiation of compressions in the current algorithm.
QUESTION 3

A 32-year-old male with a history of asthma is experiencing severe
respiratory distress. He is speaking in 2-3 word sentences, has a
respiratory rate of 32, and an SpO2 of 88% on room air. Auscultation
reveals diminished breath sounds with faint wheezing. What is the
MOST appropriate initial treatment?
A) Administer albuterol via nebulizer.
B) Administer high-flow oxygen via non-rebreather mask.
C) Administer epinephrine 1:1000 IM.
D) Assist ventilations with a bag-valve-mask (BVM) device.
Answer: D
Explanation: This patient is in severe respiratory failure, indicated by the
diminished breath sounds, altered speech pattern, hypoxia, and
tachypnea. Diminished breath sounds in asthma are a sign of impending
respiratory arrest, indicating that air movement is severely
compromised. The priority is to support ventilation with a BVM to
ensure adequate oxygenation and ventilation. While albuterol and
epinephrine are appropriate for asthma, they will not be effective if the
patient cannot move air. High-flow oxygen alone may not provide
adequate ventilation. The immediate lifesaving intervention is assisted
ventilation.
QUESTION 4
Which of the following findings is MOST indicative of cardiac
tamponade following blunt chest trauma?
A) Hypotension, muffled heart sounds, and jugular venous distention.
, 4|Page
B) Hypertension, bradycardia, and bounding pulses.
C) Tachycardia, hypertension, and crackles in the lung bases.
D) Hypotension, tachycardia, and unequal breath sounds.
Answer: A
Explanation: Beck's triad (hypotension, muffled heart sounds, and
jugular venous distention) is the classic presentation of cardiac
tamponade. The accumulation of fluid in the pericardial sac compresses
the heart, reducing cardiac output and causing hypotension. The fluid
also dampens heart sounds and impedes venous return to the right
heart, causing JVD. The other options describe different pathologies:
hypertension and bounding pulses are not typical of tamponade;
tachycardia with hypertension and crackles suggests pulmonary edema
or heart failure; hypotension with unequal breath sounds is more
suggestive of a tension pneumothorax.
QUESTION 5
A 70-year-old female presents with a sudden onset of severe, tearing
chest pain that radiates to her back. Her blood pressure is 150/90 in the
right arm and 110/70 in the left arm. Which of the following is the
MOST likely diagnosis?
A) Acute myocardial infarction.
B) Pulmonary embolism.
C) Aortic dissection.
D) Pericarditis.
