Read the first 7 Cardiac Arrest flashcards as text

  1. A 55-year-old collapses at a community event. An AED is available. Two rescuers arrive together. What is the correct sequence of actions?

    Answer: Verify unresponsiveness, activate EMS, begin CPR, apply AED when ready

    The correct sequence is verify responsiveness, activate EMS, start CPR, and apply the AED as soon as it is available.

  2. Which of the following rescuer actions is most likely to decrease CPR quality?

    Answer: Leaning on the chest between compressions

    Leaning on the chest prevents full recoil, reducing venous return and cardiac filling — directly degrading CPR quality.

  3. When is it acceptable to withhold or stop CPR in a pre-hospital setting?

    Answer: When the patient has a valid Do Not Resuscitate (DNR) order

    A valid DNR or POLST order indicating the patient's wish to forgo resuscitation is a legal and ethical reason to withhold CPR.

  4. During a resuscitation, a rescuer performing compressions notices she is fatigued after 2 minutes. What should happen?

    Answer: She should switch compressor roles with another team member during the next rhythm check

    Rescuers should rotate compressor roles approximately every 2 minutes (at rhythm checks) to prevent fatigue and maintain compression quality.

  5. A child is found submerged in a pool and is unresponsive and not breathing. She has no pulse. What modification to standard CPR sequencing applies?

    Answer: Give 2 minutes of CPR before activating EMS if alone

    For a lone rescuer with a pediatric drowning victim, provide 2 minutes of CPR first before leaving to call 911, because the arrest is likely hypoxic.

  6. Which statement about hands-only CPR (compression-only CPR) is correct?

    Answer: It is appropriate for adult bystander-witnessed cardiac arrest in the first few minutes

    Hands-only CPR is acceptable for adult witnessed sudden cardiac arrest because passive oxygenation is sufficient in the first few minutes.

  7. What is the correct hand placement for performing chest compressions on an adult?

    Answer: Heel of both hands on the lower half of the sternum

    Place the heel of one hand on the lower half of the sternum, then interlock the other hand on top, keeping fingers off the chest.
