Question 1
High-quality CPR for an adult includes which of the following compression parameters?
A) Compression depth of at least 2 inches (5 cm) but no more than 2.4 inches (6 cm)
B) Compression rate of 80-100 per minute
C) Compression depth of 1.5 inches (4 cm)
D) Allowing the chest to recoil halfway between compressions
Correct Answer: A
Rationale: High-quality CPR requires compression depth of at least 2 inches (5 cm) but no more than 2.4
inches (6 cm) for adults. Compression rate is 100-120 per minute (not 80-100). Complete chest recoil
(allowing the chest to return to its normal position) is essential to allow cardiac filling; incomplete recoil
reduces cardiac output.
Question 2
An adult collapses suddenly and is unresponsive. The rescuer has activated EMS. What is the next
priority action?
A) Check for a pulse for 20 seconds
B) Begin chest compressions at a rate of 80 per minute
C) Begin chest compressions at a rate of 100-120 per minute and a depth of at least 2 inches
D) Deliver two rescue breaths
,Correct Answer: C
Rationale: Current AHA guidelines emphasize that chest compressions should be started immediately for
any unresponsive victim with no breathing or no normal breathing (i.e., agonal gasping). The sequence is
C-A-B (Compressions-Airway-Breathing). Compressions should be at a rate of 100-120 per minute, depth
at least 2 inches (5 cm), and allow full chest recoil.
Question 3
The proper hand placement for chest compressions on an adult is:
A) The lower half of the sternum between the nipples
B) The xiphoid process
C) The left side of the chest over the heart
D) The upper third of the sternum
Correct Answer: A
Rationale: Proper hand placement for adult chest compressions is the center of the chest on the lower
half of the sternum, between the nipples. Avoid the xiphoid process (can cause liver injury). Placing
hands over the heart (left chest) is incorrect and reduces effectiveness.
Question 4
Complete chest recoil is important during CPR because:
A) It allows the heart to refill with blood between compressions
B) It prevents rib fractures
C) It reduces the need for rescue breathing
D) It increases the compression rate
Correct Answer: A
,Rationale: Complete chest recoil creates negative intrathoracic pressure, which allows venous return
and cardiac filling between compressions. Incomplete recoil (leaning on the chest) increases
intrathoracic pressure, reduces venous return, decreases cardiac output, and increases coronary
perfusion pressure.
Question 5
A rescuer is performing CPR on an adult. An AED arrives. The rescuer should:
A) Continue CPR while the AED is being set up
B) Stop CPR immediately and apply the AED
C) Deliver two more rescue breaths before using the AED
D) Move the patient to a different location before using the AED
Correct Answer: A
Rationale: CPR should continue while the AED is being turned on and pads are being applied. The
rescuer should minimize interruptions in chest compressions. Pause CPR only when the AED is analyzing
the rhythm and when a shock is being delivered. After shock delivery, resume CPR immediately.
Question 6
The recommended compression-to-ventilation ratio for single-rescuer adult CPR is:
A) 30:2
B) 15:2
C) 30:1
D) 15:1
Correct Answer: A
, Rationale: The compression-to-ventilation ratio for adult CPR is 30:2 for both single-rescuer and two-
rescuer CPR. For children and infants, the ratio is 30:2 for single-rescuer and 15:2 for two-rescuer CPR.
The 30:2 ratio simplifies training and improves compression fraction.
Question 7
The pulse check for an adult should take no longer than:
A) 5 seconds
B) 10 seconds
C) 15 seconds
D) 30 seconds
Correct Answer: B
Rationale: The pulse check should take no longer than 10 seconds. If no pulse is definitely felt within 10
seconds (or if the rescuer is unsure), begin CPR immediately. Prolonged pulse checks delay chest
compressions and reduce survival.
Question 8
When performing CPR on an adult, the rescuer should switch compressors every:
A) 1 minute
B) 2 minutes (or when fatigued)
C) 5 minutes
D) 10 minutes
Correct Answer: B
Rationale: Rescuers should switch compressors approximately every 2 minutes (or sooner if fatigued) to
maintain high-quality compressions. The switch should take less than 5 seconds to minimize
interruptions. AED analysis and shock delivery are opportunities for rescuers to switch.
