ANSWERS WITH RATIONALE ALREADY A+ GRADED
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 60-80 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 (2 inches for children, 1.5 inches for infants). Compression rate is 100-120 per
minute. 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
Two rescuers are performing CPR on an adult in cardiac arrest. The compression-to-ventilation ratio for
two-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 (except for neonates). For children and infants, the ratio is 15:2 for two-rescuer CPR. The
change to 30:2 for adults simplifies training and improves compression fraction.
Question 3
A 55-year-old man collapses suddenly. He is unresponsive, not breathing, and has no pulse. 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. 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 4
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 5
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 6
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 7
A child collapses in a school gymnasium. The child is unresponsive and not breathing. A lay rescuer
should:
A) Start CPR with a compression-to-ventilation ratio of 30:2
B) Start CPR with a compression-to-ventilation ratio of 15:2
C) Provide only rescue breaths without compressions
D) Wait for EMS to arrive before starting CPR
Correct Answer: A
Rationale: For lay rescuers (non-healthcare providers), the compression-to-ventilation ratio is 30:2 for all
ages (adults, children, infants) during single-rescuer CPR. Healthcare providers use 30:2 for single-
rescuer and 15:2 for two-rescuer child/infant CPR.
Question 8
The most common cause of cardiac arrest in children and infants is:
A) Ventricular fibrillation
B) Respiratory failure or shock leading to hypoxic arrest
C) Myocardial infarction
D) Pulmonary embolism
Correct Answer: B
