BLS CPR Techniques & Procedures 5 — Questions and Answers
Question 1: What is 'CPR feedback' technology designed to do?
- Alert rescuers when the AED has charged
- Provide real-time audio or visual prompts to help rescuers achieve correct compression rate and depth (Correct answer)
- Automatically deliver compressions without human effort
- Monitor the patient's heart rhythm during CPR
Correct answer: Provide real-time audio or visual prompts to help rescuers achieve correct compression rate and depth
CPR feedback devices provide real-time prompts on rate, depth, and recoil to help rescuers maintain high-quality compressions.
Question 2: A rescuer is performing CPR on an adult and the AED advises 'no shock recommended.' What should the rescuer do?
- Stop CPR and wait for EMS to arrive
- Immediately resume CPR beginning with chest compressions (Correct answer)
- Check the victim's pulse for up to 30 seconds
- Reattach the AED pads and re-analyze
Correct answer: Immediately resume CPR beginning with chest compressions
When the AED gives a 'no shock' message, the rescuer should immediately resume CPR starting with compressions.
Question 3: During an active resuscitation, which intervention should NOT interrupt chest compressions for more than 10 seconds?
- AED rhythm analysis
- Endotracheal intubation by advanced providers
- Checking for a carotid pulse
- All of the above (Correct answer)
Correct answer: All of the above
All of these interventions — rhythm analysis, intubation, and pulse checks — should be limited to no more than 10 seconds of interruption to compressions.
Question 4: What is the recommended action if a victim vomits during CPR?
- Continue CPR without interruption
- Turn the victim to the side, clear the airway, then resume CPR (Correct answer)
- Stop CPR and place the victim in the recovery position permanently
- Increase the rate of rescue breaths to clear the airway
Correct answer: Turn the victim to the side, clear the airway, then resume CPR
The victim should be turned to the side to clear vomit from the airway, then CPR should be resumed as quickly as possible.
Question 5: Which of the following scenarios is an indication to stop CPR?
- The victim remains pulseless after 10 minutes of CPR
- ROSC occurs, a valid DNR is produced, or rescuers are physically unable to continue (Correct answer)
- The AED has delivered three consecutive shocks without response
- Bystanders request that CPR be stopped
Correct answer: ROSC occurs, a valid DNR is produced, or rescuers are physically unable to continue
CPR should be stopped when ROSC is achieved, a valid DNR is presented, or rescuers are physically exhausted with no additional help available.
Question 6: What should a rescuer do if the victim shows obvious signs of life during CPR?
- Continue CPR for 2 more minutes to confirm ROSC
- Stop compressions and reassess breathing and pulse (Correct answer)
- Deliver two rescue breaths and then reassess
- Apply the AED and check for a shockable rhythm
Correct answer: Stop compressions and reassess breathing and pulse
If signs of life appear (breathing, movement, coughing), compressions should stop and the rescuer should reassess pulse and breathing.
Question 7: In the context of BLS, what does 'high-performance CPR' emphasize?
- Using the most advanced airway device available
- Minimizing interruptions, achieving correct rate and depth, and ensuring full recoil with team coordination (Correct answer)
- Delivering rescue breaths at a faster rate than standard guidelines
- Rotating compressors every 5 minutes to maintain energy
Correct answer: Minimizing interruptions, achieving correct rate and depth, and ensuring full recoil with team coordination
High-performance CPR focuses on minimizing interruptions, correct compression rate/depth, full recoil, and coordinated team roles to optimize outcomes.
