Detailed Answers| Brand New Version!
Question 1
Which of the following victims requires the immediate start of high-quality CPR?
A) A victim who is complaining of severe chest pain and nausea
B) A victim who is unresponsive but has a strong, regular pulse and is breathing normally
C) A victim with a pulse who is struggling to breathe due to an asthma attack
D) A victim who is unresponsive with no normal breathing and no definitive pulse
E) A victim who is awake but cannot speak because they are choking
Correct Answer: D) A victim who is unresponsive with no normal breathing and no normal
pulse
Rationale: CPR is indicated for victims in cardiac arrest. Clinical indicators of cardiac
arrest include unresponsiveness, the absence of normal breathing (or only agonal gasps),
and the absence of a detectable pulse within 10 seconds. If any of these three elements are
missing, the victim is in cardiac arrest.
Question 2
When a victim has a suspected neck or spinal injury, what is the preferred method to open the
airway to provide breaths?
A) The Jaw-thrust maneuver
B) The Head tilt-chin lift
C) The Head tilt only
D) The Tongue lift-finger sweep
E) No airway opening should be attempted to avoid paralysis
Correct Answer: A) Use the Jaw-thrust maneuver
Rationale: In a victim with a suspected spinal injury, the Jaw-thrust maneuver is used
because it minimizes movement of the cervical spine. If the jaw-thrust does not effectively
open the airway, the rescuer should use the head tilt-chin lift, as maintaining an open
airway is a priority.
Question 3
What is the correct amount of time a healthcare provider should take to check for a pulse and
simultaneously look for breathing?
A) No more than 3 seconds
B) Exactly 5 seconds
C) At least 15 seconds
D) Between 5 and 10 seconds
E) Until you are 100% certain you feel a pulse
Correct Answer: D) Between 5 and 10 seconds
Rationale: The pulse check should take at least 5 seconds but no more than 10 seconds. This
, 2
ensures you do not waste valuable time if a pulse is absent, but gives you enough time to
detect a slow or weak heart rate.
Question 4
Which of the following ventilation devices is NOT recommended for use by a single rescuer
during 1-rescuer CPR?
A) Mouth-to-barrier device
B) Bag-mask device
C) Mouth-to-mouth technique
D) Mouth-to-mask technique
E) All of the above are appropriate for a single rescuer
Correct Answer: B) Bag-mask device
Rationale: A bag-mask device is not recommended for a single rescuer because it is very
difficult to maintain an effective seal with one hand while squeezing the bag with the other.
It is most effective when used during 2-rescuer CPR, where one rescuer seals the mask and
the other squeezes the bag.
Question 5
When performing chest compressions on an adult, what is the recommended depth of
compressions?
A) At least 2 inches (5 cm)
B) At least 1 inch (2.5 cm)
C) At least 4 inches (10 cm)
D) At least 3 inches (7.5 cm)
E) One-third the depth of the chest
Correct Answer: A) At least 2 inches (5 cm)
Rationale: High-quality CPR requires compressions of adequate depth. For adults, this is at
least 2 inches (5 cm). You should avoid compressing deeper than 2.4 inches (6 cm) because
excessive depth can cause internal injuries without improving outcomes.
Question 6
A 5-year-old child has a pulse of 80 beats per minute but is not breathing. What is the correct
action for the rescuer?
A) Start full CPR with chest compressions and breaths
B) Give chest compressions without breaths
C) Give rescue breaths only without chest compressions
D) Attach the AED immediately and deliver a shock
E) Perform abdominal thrusts to clear a possible obstruction
Correct Answer: C) Give breaths without chest compressions
Rationale: If a pediatric victim has a pulse greater than 60 beats per minute but is not
, 3
breathing (respiratory arrest), the rescuer should provide rescue breathing. For a child,
this is 1 breath every 2 to 3 seconds.
Question 7
What is the correct compression-to-ventilation ratio for 1-rescuer adult CPR?
A) 15:2
B) 30:2
C) 20:2
D) 5:1
E) 30:1
Correct Answer: B) 30:2
Rationale: The standard ratio for a single rescuer treating an adult is 30 compressions
followed by 2 breaths. This ratio is used for all adult victims regardless of the number of
rescuers present.
Question 8
What is the recommended compression rate for all age groups during CPR?
A) 100 to 120 per minute
B) As many as you can (at least 150/min)
C) Exactly 100 per minute
D) 60 to 80 per minute
E) 120 to 140 per minute
Correct Answer: A) Between 100 and 120 per minute (Note: User source said 100-200, but
standard AHA is 100-120).
Rationale: The optimal rate for chest compressions is between 100 and 120 per minute.
Compressing too slowly results in inadequate blood flow, while compressing too fast does
not allow the heart to refill with blood between compressions.
Question 9
During 2-rescuer CPR, while the first rescuer provides chest compressions, what is the primary
role of the second rescuer?
A) Monitor the victim for spontaneous movement
B) Manually record the times of each cycle
C) Open the airway and give effective breaths
D) Call the victim's family members
E) Perform a secondary physical assessment
Correct Answer: C) Open the airway and give breaths
Rationale: In 2-rescuer CPR, the roles are divided to reduce fatigue and increase
effectiveness. One rescuer focuses on compressions, and the second rescuer focuses on
maintaining the airway and delivering ventilations.

Question 10
When performing chest compressions on an adult, where should the rescuer’s hands be placed?
A) On the tip of the xiphoid process (breastbone)
B) On the upper part of the abdomen near the ribs
C) On the lower half of the breastbone
D) On the left side of the chest over the heart
E) On the center of the collarbone
Correct Answer: C) On the lower half of the breastbone (User source said "Center of chest"
which refers to the same anatomical location).
Rationale: Proper hand placement ensures that you are compressing the heart against the
spine to pump blood. Placing hands on the lower half of the breastbone (sternum) avoids
the xiphoid process, which could break and damage internal organs.
Question 11
Immediately after an AED delivers a shock to a victim, what should you do?
A) Restart CPR immediately, beginning with chest compressions
B) Wait for the AED to reanalyze the rhythm before touching the victim
C) Check for a pulse for 10 seconds
D) Give 2 breaths and then check the rhythm
E) Turn the AED off and call for help
Correct Answer: A) restart CPR, beginning with chest compressions
Rationale: Modern AED protocols require immediate resumption of CPR after a shock is
delivered. You should not wait for a pulse check or a re-analysis. CPR helps circulate the
oxygenated blood until the heart can establish a viable rhythm on its own.
Question 12
During 2-rescuer CPR on an infant, what is the correct compression-to-ventilation ratio?
A) 5:1
B) 30:2
C) 15:2
D) 15:1
E) 3:1
Correct Answer: C) 15:2
Rationale: For children and infants, the compression-to-ventilation ratio changes from 30:2
(for 1 rescuer) to 15:2 (for 2 rescuers). This provides more frequent ventilations for
pediatric victims, who are more likely to have a respiratory cause for cardiac arrest.
Question 13
Which sign indicates that you are providing effective breaths with a bag-mask device or pocket
mask?
A) The chest will rise with each breath
