  1. When performing CPR on an adult, what is the correct compression-to-ventilation ratio?

    Answer: 30:2

    The current standard for adult CPR is 30 chest compressions followed by 2 rescue breaths.

  2. How deep should chest compressions be for an adult during CPR?

    Answer: At least 2 inches but no more than 2.4 inches

    Adult chest compressions should be at least 2 inches but no more than 2.4 inches to be effective without causing excessive injury.

  3. After delivering a shock with an AED, what should the rescuer do immediately?

    Answer: Resume CPR starting with chest compressions

    Immediately after an AED shock, resume CPR beginning with chest compressions to circulate any restored cardiac output.

  4. A worker is unresponsive and not breathing normally. You have started CPR. When the AED arrives, you should:

    Answer: Turn on the AED, apply pads, and minimize interruptions to CPR

    Turn on the AED and apply pads as quickly as possible while minimizing any interruptions to chest compressions.

  5. Which of the following is a contraindication for placing an AED pad?

    Answer: The patient has a transdermal medication patch on the chest

    Transdermal medication patches must be removed and the skin wiped before placing AED pads to ensure proper shock delivery and avoid burns.

  6. What is the purpose of allowing full chest recoil between compressions during CPR?

    Answer: To allow the heart to refill with blood

    Full chest recoil allows the heart chambers to refill with blood, which is then pumped forward with the next compression.

  7. In the context of AED use, what does the term 'shockable rhythm' refer to?

    Answer: Ventricular fibrillation or pulseless ventricular tachycardia

    Shockable rhythms are ventricular fibrillation (VF) and pulseless ventricular tachycardia (pVT), both of which can be converted by defibrillation.
