1. A healthcare provider approaches an adult who suddenly collapsed in a clinical area.
After confirming scene safety, what should the provider do next?
A. Immediately administer two rescue breaths
B. Check the person's responsiveness
C. Obtain a blood pressure reading
D. Place the person in the recovery position
The initial assessment includes confirming scene safety and checking responsiveness before
proceeding with further BLS actions.
2. An adult patient is unresponsive and has abnormal gasping respirations. How should the
provider interpret these respirations?
A. Normal breathing
B. Adequate ventilation
C. Agonal breathing consistent with possible cardiac arrest
D. Respiratory recovery
Gasping or only occasional abnormal breaths are not normal breathing and should be treated
as a sign of possible cardiac arrest when the patient is unresponsive.
3. When assessing an adult for cardiac arrest, how long should a healthcare provider
simultaneously check breathing and pulse?
A. At least 5 but no more than 10 seconds
B. 15–20 seconds
C. 30 seconds
D. At least 1 minute
The current Red Cross BLS sequence calls for simultaneous assessment of breathing and pulse
for at least 5 but no more than 10 seconds.
4. An adult is unresponsive, is not breathing normally, and has no definite pulse. What is
the priority intervention?
A. Give naloxone
B. Obtain a blood glucose level
,C. Place the patient in a seated position
D. Start CPR
An unresponsive adult who is not breathing normally and has no definite pulse is in cardiac
arrest and requires immediate CPR.
5. During adult CPR without an advanced airway, which compression-to-ventilation ratio
should be used?
A. 15:2
B. 30:2
C. 5:1
D. 30:1
Adult CPR without an advanced airway uses cycles of 30 chest compressions followed by 2
ventilations.
6. While performing adult CPR, an AED becomes available. What should the team do?
A. Continue CPR for another 10 minutes before using it
B. Wait until an advanced airway is placed
C. Apply and use the AED as soon as possible
D. Give two additional minutes of rescue breathing first
Early defibrillation can improve outcomes in shockable cardiac arrest, so the AED should be
used as soon as it is available.
7. An AED announces that it is analyzing the patient's rhythm. What should the rescuers
do?
A. Stop touching the patient and allow analysis to occur
B. Continue compressions while the AED analyzes
C. Remove the AED pads
D. Begin rescue breathing
Everyone must stay clear of the patient during AED rhythm analysis so the device can
accurately analyze the rhythm and avoid interference.
8. An AED advises a shock for an adult in cardiac arrest. What should occur immediately
after the shock is delivered?
A. Check the pulse for 30 seconds
B. Wait for the AED to announce another shock
C. Place the patient in the recovery position
D. Resume CPR immediately
,After a shock, CPR should be resumed immediately, generally continuing for about 2 minutes
or until the AED is ready to analyze again.
9. Which finding most strongly indicates cardiac arrest in an adult?
A. Slow but regular breathing
B. Unresponsiveness with absent normal breathing and no definite pulse
C. Chest discomfort with normal breathing
D. Mild shortness of breath
Cardiac arrest is identified by unresponsiveness combined with absent normal breathing and
an absent definite pulse.
10. A provider finds an adult who is unresponsive but breathing normally and has a
definite pulse. What is the appropriate immediate approach?
A. Begin chest compressions
B. Deliver 30 compressions followed by 2 breaths
C. Position the patient appropriately, monitor, and provide further assessment
D. Apply the AED and deliver a shock
A patient with a pulse and normal breathing is not in cardiac arrest. The provider should
position, monitor, reassess, and address the underlying condition.
11. An adult has a pulse but is not breathing effectively. What ventilation rate is
recommended during respiratory arrest?
A. One ventilation every 2 seconds
B. One ventilation every 6 seconds
C. One ventilation every 15 seconds
D. Two ventilations every 30 seconds
For an adult with a pulse but ineffective or absent breathing, provide one ventilation every 6
seconds and reassess breathing and pulse about every 2 minutes.
12. A provider is ventilating an adult with a pulse. What is the primary goal of each
ventilation?
A. Produce visible chest rise
B. Inflate the stomach
C. Deliver the largest possible breath
D. Cause coughing
Each ventilation should be sufficient to produce visible chest rise while avoiding excessive
ventilation.
, 13. During CPR, a rescuer notices that chest compressions are becoming progressively
slower. What is the best team response?
A. Stop CPR permanently
B. Switch to rescue breathing only
C. Reduce the compression depth
D. Rotate the compressor approximately every 2 minutes when possible
Changing compressors approximately every 2 minutes helps reduce fatigue and maintain
high-quality compressions.
14. Which characteristic is most important when performing adult chest compressions?
A. Frequent prolonged pauses
B. Shallow compressions
C. Adequate depth with complete chest recoil
D. Compressing only during exhalation
High-quality CPR requires effective compression depth and complete chest recoil so the heart
can refill between compressions.
15. Why is minimizing interruptions in chest compressions important during CPR?
A. It maintains blood flow to vital organs
B. It prevents the AED from turning on
C. It eliminates the need for ventilation
D. It guarantees return of spontaneous circulation
Frequent interruptions reduce blood flow generated by CPR. Minimizing interruptions
supports continuous perfusion of the heart and brain.
16. Two healthcare providers are caring for an adult in cardiac arrest. Which action best
demonstrates effective team dynamics?
A. Both providers perform compressions simultaneously
B. One provider clearly assigns tasks and confirms completion
C. Neither provider communicates to avoid distraction
D. The least experienced provider directs all care without assistance
Clear role assignment, closed-loop communication, and confirmation of completed tasks
promote coordinated resuscitation.
17. A team leader asks a rescuer to retrieve the AED. The rescuer repeats the instruction
and later confirms that the AED has arrived. What communication principle is
demonstrated?
