First Aid CPR and AED Procedures Questions and Answers

Question 1

When performing CPR on an adult, what is the correct rate and depth for chest compressions?

Accepted Answer

A rate of 100-120 compressions per minute and a depth of at least 2 inches.

Answer

According to the American Red Cross and American Heart Association guidelines, high-quality CPR on an adult requires a compression rate of 100 to 120 per minute and a depth of at least 2 inches (5 cm) but not more than 2.4 inches (6 cm). This ensures adequate blood circulation to vital organs.

Question 2

You are responding to a person who has collapsed. After ensuring the scene is safe and checking for responsiveness, you find they are not breathing. An AED has just arrived. What is the immediate next step?

Accepted Answer

Turn on the AED and follow its prompts.

Answer

As soon as an AED is available, it should be used immediately. The first step in using an AED is to turn it on. The device will then guide you through the next steps, including pad placement and analysis of the heart rhythm. Early defibrillation is critical for survival in cases of sudden cardiac arrest.

Question 3

Which of the following describes the correct placement for AED pads on an adult?

Accepted Answer

One pad on the upper right side of the chest and the other on the lower left side of the chest.

Answer

The standard anterolateral placement for AED pads on an adult is to place one pad on the upper right side of the bare chest (below the collarbone) and the other pad on the lower left side of the chest, under the armpit. This allows the electrical shock to pass through the heart.

Question 4

A rescuer is performing CPR on an infant (under 1 year old). Which technique should be used for chest compressions?

Accepted Answer

Two fingers in the center of the chest, just below the nipple line.

Answer

For an infant, chest compressions should be performed using two fingers (or two thumbs with hands encircling the chest if two rescuers are present) in the center of the chest, just below the nipple line. The compression depth should be about 1.5 inches (4 cm).

Question 5

After an AED delivers a shock, what is the most appropriate immediate action?

Accepted Answer

Immediately resume chest compressions.

Answer

Immediately after a shock is delivered (or if no shock is advised), the rescuer should resume high-quality chest compressions. Minimizing interruptions to chest compressions is crucial for maintaining blood flow to the brain and heart. The AED will typically prompt you to begin CPR.
