b. full recoil of the chest should occur with each compression.
c. push at a moderate rate with a depth of no more than 1 inch.
d. switch doing compressions only when absolutely necessary.

1. ______ is the application of an electric shock to correct lethal heart arrhythmias.

a. reanimation
b. defibrillation
c. artificial conduction
d. cardiopulmonary resuscitation

1. ______ is a heart rhythm that requires a shock from an aed.

a. ventricular fibrillation
b. asystole
c. pulseless electrical activity (pea)
d. heart block

1. typically aed adhesive pads should be placed with one on the upper ____ chest and the other one on the patients side a few inches below the ____ armpit.

a. left, left
b. right, left
c. left, right
d. right, right

1. you find a patient who was down for four to five minutes prior to your arrival. for how many minutes should you perform cpr before applying the aed?

Explanation:

1.

• For option a: Interruptions in CPR compressions should be minimized, not up to 30 seconds.
• For option b: Full recoil of the chest with each compression is crucial for effective blood circulation during CPR.
• For option c: The depth of compressions should be at least 2 inches (for adults), not no more than 1 inch.
• For option d: Switching compressions should be done regularly (e.g., every 2 minutes) to prevent compressor fatigue, not only when absolutely necessary.

2.

• Defibrillation is the process of delivering an electric shock to correct lethal heart arrhythmias. Reanimation is a more general term for restoring life, artificial conduction is not the standard term for this process, and cardiopulmonary resuscitation (CPR) is a combination of compressions and ventilations, not specifically the electric - shock part.

3.

• Ventricular fibrillation is a chaotic heart rhythm that can be corrected by a shock from an AED. Asystole (no electrical activity), pulseless electrical activity (organized electrical activity but no mechanical contraction), and heart block (a conduction problem) do not typically respond to an AED shock in the same way as ventricular fibrillation.

4.

• Typically, one AED pad is placed on the upper right chest (just below the collarbone) and the other on the left side of the chest a few inches below the armpit.

5.

• If a patient has been down for 4 - 5 minutes before arrival, it is recommended to perform 2 minutes of CPR before applying the AED. This helps to circulate oxygenated blood (from any residual oxygen in the lungs) to the heart and brain before the AED is used.

Answer:

1. B. Full recoil of the chest should occur with each compression.
2. B. Defibrillation
3. A. Ventricular fibrillation
4. B. right, left
5. 2 minutes.
