Medical Surgical Critical Care BLS & CPR #3

Question

Which is the correct guideline for CPR on an adult for a health care provider? Select all that apply.

Answers

  1. Provide 30 compressions with 2 rescue breaths.
    • Rationale:

      This answer is correct because when providing CPR to an adult, one should provide 30 compressions with 2 rescue breaths. The rate of compressions should be between 100-120 per minute. Between every compression, the chest should recoil completely to allow the heart chambers to refill with blood to get as much oxygenated blood out to the body as possible.

  2. Assess the carotid pulse in 10 seconds or less.
    • Rationale:

      This answer is correct because it is important to minimize delays before chest compressions. If the person has a pulse, maintain the airway, and begin the rescue breathing only.

  3. Pause compressions every 5 minutes to reassess pulse.
    • Rationale:

      This answer is not correct because interruptions to chest compressions should be kept to a minimum. The pause to reassess the pulse should occur every 2 minutes and take no longer than 10 seconds.

  4. Place AED pads upper left chest and right lateral chest.
    • Rationale:

      This answer is not correct because the leads should be placed on the upper right chest and left lateral chest below the nipple line and under the armpit. This correct placement allows for an electrical shock to travel through the heart muscle.

  5. Depth of compressions should be 2-2.4 inches.
    • Rationale:

      This answer is correct because it gives the chest time to recoil completely. This increases venous return. It improves chances for the client when the AED is used, as well as those who cannot be treated with a defibrillator shock.

Overview

Assessing the pulse of an adult who is unresponsive should take less than 10 seconds. Adult CPR requires 30 compressions at a depth of 2-2.4 inches with 2 rescue breaths.

Explanation

Learning Outcomes

The CPR guidelines for an adult are as follows: If there is no response from the client, assess for the pulse taking no longer than 10 seconds. If CPR is indicated, start compressions at a rate of 30:2 rescue breaths. Shout for help, activating the emergency response system. Compressions should be performed with a depth of between 2-2.4 inches to increase venous return. The pulse should be reassessed every 2 minutes. AED pads are placed on the upper right chest and left lateral chest if there is no pulse. Follow the instructions given by the AED.

Test Taking Tip

Remember CAB for compressions, airway, and breaths.
