1. What is the recommended compression rate for adult CPR?
a) 60–80 compressions per minute
b) 80–100 compressions per minute
c) 100–120 compressions per minute
d) 120–140 compressions per minute
c) 100–120 compressions per minute
Maintaining a rate of 100–120 per minute ensures effective blood
circulation during CPR.
2. What is the recommended depth of chest compressions for an
adult?
a) At least 1 inch (2.5 cm)
b) At least 1.5 inches (4 cm)
c) At least 2 inches (5 cm)
d) At least 3 inches (7.5 cm)
c) At least 2 inches (5 cm)
Compression depth of at least 2 inches is needed to create adequate
blood flow to vital organs.
3. When performing CPR on a child, the recommended compression-
to-ventilation ratio for a single rescuer is:
, a) 15:2
b) 30:2
c) 5:1
d) 20:2
b) 30:2
For single rescuers, the adult compression ratio is applied to children as
well; 30 compressions followed by 2 breaths.
4. The first action when you arrive at an unresponsive adult patient
is:
a) Begin chest compressions immediately
b) Check for breathing and pulse
c) Call emergency services (activate EMS)
d) Give 2 rescue breaths
c) Call emergency services (activate EMS)
Early activation of EMS improves survival outcomes and ensures
advanced care is on the way.
5. If an adult patient is unresponsive but breathing normally, you
should:
a) Begin CPR
b) Place them in the recovery position and monitor
c) Give rescue breaths only
d) Call for AED
b) Place them in the recovery position and monitor
If breathing is present, protect the airway and monitor until help arrives.
6. How many seconds should you check for a pulse in an adult?
a) 5–10 seconds
, b) 10–15 seconds
c) 15–20 seconds
d) 20–30 seconds
a) 5–10 seconds
Checking the pulse for no more than 10 seconds ensures minimal delay
in starting CPR.
7. When using an AED, the first step after turning it on is:
a) Deliver a shock immediately
b) Attach pads to patient’s bare chest
c) Check for pulse
d) Begin CPR
b) Attach pads to patient’s bare chest
AED pads must be placed on a bare chest to properly analyze heart
rhythm and deliver a shock if indicated.
8. In a two-rescuer adult CPR scenario, the recommended
compression-to-ventilation ratio is:
a) 15:2
b) 30:2
c) 5:1
d) 20:2
b) 30:2
For adults, the ratio remains 30:2 regardless of single or two rescuers;
for children, two rescuers use 15:2.
9. For an infant (under 1 year), the compression depth should be:
a) About 1 inch (2.5 cm)
b) About 1.5 inches (4 cm)
, c) About 2 inches (5 cm)
d) About 2.5 inches (6 cm)
b) About 1.5 inches (4 cm)
Infant chest compressions should be one-third the depth of the chest,
approximately 1.5 inches.
10. If a choking adult becomes unresponsive, the next step is:
a) Continue abdominal thrusts
b) Begin CPR starting with chest compressions
c) Give back blows
d) Attempt finger sweep
b) Begin CPR starting with chest compressions
If the patient loses consciousness, chest compressions may help dislodge
the object.
11. What is the ratio of compressions to ventilations for infant
CPR with two rescuers?
a) 30:2
b) 15:2
c) 5:1
d) 20:2
b) 15:2
Two rescuers use 15 compressions to 2 breaths for infants to increase
oxygen delivery.
12. When performing CPR, you should allow complete chest
recoil after each compression. This is important because:
a) It prevents rib fractures
b) It allows the heart to refill with blood
