1. You arrive at a scene where a patient is unresponsive and gasping. What is your
immediate next step?
A. Begin chest compressions
B. Deliver two rescue breaths
C. Check for a carotid pulse
D. Apply the AED
Answer: C. Check for a carotid pulse
Rationale: Always check for a pulse before initiating compressions in an unresponsive patient.
2. A 45-year-old male presents with chest pain radiating to the jaw and left arm. Which of
the following should you do first?
A. Apply oxygen if needed and prepare for transport
B. Administer nitroglycerin
C. Begin CPR
D. Place AED pads
Answer: A. Apply oxygen if needed and prepare for transport
Rationale: Oxygen and rapid transport are priorities in suspected cardiac cases if the patient is
alert and breathing.
3. What is the appropriate compression-to-ventilation ratio for an adult in two-rescuer
CPR?
A. 15:2
B. 30:2
,C. 5:1
D. 20:2
Answer: B. 30:2
Rationale: The ratio for adult CPR remains 30:2, regardless of the number of rescuers.
4. What is the most common cause of airway obstruction in an unconscious patient?
A. Swollen tonsils
B. Tongue
C. Foreign object
D. Vomitus
Answer: B. Tongue
Rationale: In unconscious patients, the tongue falls back and blocks the airway.
5. Which organ is most susceptible to damage from hypoperfusion?
A. Lungs
B. Brain
C. Kidneys
D. Liver
Answer: B. Brain
Rationale: The brain is highly sensitive to lack of oxygen and blood flow.
6. Which of the following is a contraindication for using a nasopharyngeal airway (NPA)?
A. Unconsciousness
B. Gag reflex present
C. Facial trauma
D. Unresponsive patient with snoring respirations
Answer: C. Facial trauma
Rationale: An NPA can enter the brain through a fractured cribriform plate.
7. What is the minimum systolic BP for a palpable radial pulse?
A. 60 mmHg
B. 70 mmHg
C. 80 mmHg
D. 90 mmHg
Answer: D. 90 mmHg
Rationale: Radial pulses generally indicate a systolic pressure of at least 90 mmHg.
, 8. When using a bag-valve mask (BVM), how many breaths per minute should be
delivered to an apneic adult?
A. 6
B. 10–12
C. 14–16
D. 20
Answer: B. 10–12
Rationale: For adults without adequate breathing, ventilate at 10–12 breaths/min.
9. A patient presents with cool, clammy skin, rapid pulse, and low BP. You suspect:
A. Stroke
B. Hypoglycemia
C. Shock
D. Hyperthermia
Answer: C. Shock
Rationale: These are classic signs of compensated shock.
10. What is the appropriate treatment for a sucking chest wound?
A. Cover with dry gauze
B. Leave open to the air
C. Seal with an occlusive dressing
D. Begin CPR
Answer: C. Seal with an occlusive dressing
Rationale: A sucking chest wound requires immediate occlusion to prevent a pneumothorax
11. What is the first step in controlling external bleeding?
A. Tourniquet application
B. Pressure point compression
C. Direct pressure
D. Elevation
Answer: C. Direct pressure
12. Which of the following is a sign of compensated shock?
A. Bradycardia
B. Decreased respirations
C. Rapid, weak pulse
D. Unresponsiveness
Answer: C. Rapid, weak pulse
