1. Which of the following is the recommended depth of chest compressions for adults during CPR?
A. 2 inches
B. 1 inch
C. 3 inches
D. 4 inches
Answer: A. 2 inches
Rationale: The recommended depth of chest compressions for adults is 2 inches to ensure adequate
blood flow.
2. In which position should the patient be placed before initiating CPR?
A. Supine position
B. Prone position
C. Lateral position
D. Trendelenburg position
Answer: A. Supine position
Rationale: The patient should be placed in the supine position to facilitate effective chest compressions.
3. Which technique should be used to open the airway during CPR?
A. Head tilt-chin lift
B. Jaw thrust
C. One-hand technique
D. Two-hand technique
Answer: A. Head tilt-chin lift
Rationale: The head tilt-chin lift technique helps to open the airway in most cases of suspected cardiac
arrest.
4. What is the recommended compression-to-ventilation ratio for two-rescuer adult CPR?
A. 30 compressions to 2 ventilations
B. 15 compressions to 2 ventilations
C. 30 compressions to 1 ventilation
D. 5 compressions to 1 ventilation
Answer: A. 30 compressions to 2 ventilations
Rationale: The recommended compression-to-ventilation ratio for two-rescuer adult CPR is 30
compressions to 2 ventilations.
5. Which of the following is a common cause of sudden cardiac arrest in adults?
A. Stroke
B. Heart failure
C. Seizure
D. Cardiac arrhythmia
Answer: D. Cardiac arrhythmia
Rationale: Cardiac arrhythmias, particularly ventricular fibrillation, are the most common cause of sudden
cardiac arrest in adults.
6. What is the recommended rate of chest compressions per minute during adult CPR?
A. 60-80 compressions
B. 80-100 compressions
