BLS CPR EXAM 2 LATEST VERSIONS (VERSION A & B)
2025/2026 ACTUAL EXAM 220 QUESTIONS AND CORRECT
DETAILED ANSWERS
Question 1
What is the very first step you should take when you encounter a potential
emergency situation?
A) Check for a pulse.
B) Begin chest compressions.
C) Ensure scene safety.
D) Call 911/activate emergency response.
E) Open the airway.
Correct Answer: C) Ensure scene safety.
Rationale: Your safety is paramount. You must first ensure the scene
is safe for yourself and the victim before approaching or providing
any care.
Question 2
When assessing an adult for responsiveness, what should you do?
A) Gently shake them and shout, "Are you okay?"
B) Yell loudly from a distance.
C) Pinch their arm firmly.
D) Check their pupils for reactivity.
E) Immediately call 911.
Correct Answer: A) Gently shake them and shout, "Are you okay?"
Rationale: To assess responsiveness in an adult, gently tap or shake
their shoulder and loudly ask, "Are you okay?"
Question 3
After determining an adult is unresponsive and not breathing, what is your
next immediate step?
A) Begin chest compressions.
B) Give two rescue breaths.
C) Check for a pulse.
D) Activate the emergency response system (call 911) and get an AED.
,E) Apply an AED immediately.
Correct Answer: D) Activate the emergency response system (call 911)
and get an AED.
Rationale: For an unresponsive, non-breathing adult, the next step is
to activate EMS (call 911) and, if possible, have someone retrieve an
AED. If alone, call 911 and retrieve the AED before starting CPR.
Question 4
What is the correct compression depth for an adult during CPR?
A) At least 1 inch (2.5 cm)
B) At least 1.5 inches (3.8 cm)
C) At least 2 inches (5 cm) but no more than 2.4 inches (6 cm)
D) At least 2.4 inches (6 cm)
E) 1/3 the depth of the chest
Correct Answer: C) At least 2 inches (5 cm) but no more than 2.4
inches (6 cm)
Rationale: High-quality chest compressions require a depth of at
least 2 inches (5 cm) for adults, but not exceeding 2.4 inches (6 cm).
Question 5
What is the correct compression rate for all ages (adult, child, infant) during
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
E) As fast as possible
Correct Answer: C) 100-120 compressions per minute
Rationale: The recommended compression rate for all age groups is
100-120 compressions per minute.
Question 6
What is the recommended compression-to-ventilation ratio for adult CPR with
,a single rescuer?
A) 15 compressions to 2 breaths
B) 30 compressions to 2 breaths
C) 5 compressions to 1 breath
D) Continuous compressions with 1 breath every 6-8 seconds
E) 10 compressions to 1 breath
Correct Answer: B) 30 compressions to 2 breaths
Rationale: For single-rescuer adult CPR, the ratio is 30 compressions
followed by 2 rescue breaths.
Question 7
When performing CPR on an adult, where should your hands be placed for
chest compressions?
A) Over the xiphoid process.
B) On the upper half of the sternum.
C) On the lower half of the sternum.
D) On the ribs just below the nipple line.
E) Anywhere on the chest.
Correct Answer: C) On the lower half of the sternum.
Rationale: Hand placement for adult chest compressions is on the
lower half of the sternum, avoiding the xiphoid process.
Question 8
After delivering a rescue breath, what should you observe to ensure it was
effective?
A) The patient's skin color changes.
B) The patient's chest visibly rises.
C) You hear a "gasp" sound.
D) The patient's legs move.
E) The stomach rises prominently.
Correct Answer: B) The patient's chest visibly rises.
Rationale: An effective rescue breath causes the patient's chest to
, visibly rise. Gastric inflation (stomach rising) indicates the breath
went into the stomach, not the lungs.
Question 9
What is the proper technique for opening the airway of an unresponsive
patient with no suspected head or neck injury?
A) Jaw-thrust maneuver.
B) Head tilt-chin lift maneuver.
C) Finger sweep.
D) Place a rolled towel under the neck.
E) Turn the patient onto their side.
Correct Answer: B) Head tilt-chin lift maneuver.
Rationale: The head tilt-chin lift maneuver is the standard method to
open the airway when a spinal injury is not suspected.
Question 10
You are performing CPR on an adult. When should you allow the chest to
recoil completely?
A) After every 5 compressions.
B) After every 10 compressions.
C) After every 30 compressions.
D) After every compression.
E) Only during rescue breaths.
Correct Answer: D) After every compression.
Rationale: Allowing full chest recoil after every compression is crucial
for high-quality CPR, as it allows the heart to refill with blood before
the next compression.
Question 11
What is the maximum amount of time you should interrupt chest
compressions for rescue breaths?
A) 5 seconds
B) 10 seconds
