Health: Order of CPR Steps (C-A-B) Practice Worksheet

Question 1

Write what the letters C-A-B stand for in the recommended order of CPR steps.

Accepted Answer

C-A-B stands for Compressions, Airway, and Breathing. The rescuer gives chest compressions first, opens the airway second, and gives rescue breaths third if trained and able.

Question 2

Place these CPR actions in the correct order: open the airway, give chest compressions, give rescue breaths.

Accepted Answer

The correct order is give chest compressions, open the airway, and give rescue breaths. This follows the C-A-B sequence.

Question 3

A student says CPR should begin with rescue breaths because oxygen is important. Explain why C-A-B starts with chest compressions instead.

Accepted Answer

C-A-B starts with chest compressions because compressions help circulate oxygen-rich blood that may already be in the body. Starting compressions quickly can help deliver blood to the brain and heart while other steps are prepared.

Question 4

You find a person who is unresponsive and not breathing normally. Before starting C-A-B, what two safety or emergency actions should happen as quickly as possible?

Accepted Answer

You should make sure the scene is safe and call emergency services or tell someone nearby to call. If an AED is available, someone should get it while CPR begins.

Question 5

Number these steps from 1 to 5: call emergency services and get an AED, check responsiveness and breathing, give rescue breaths if trained, start chest compressions, open the airway.

Accepted Answer

The correct order is 1. check responsiveness and breathing, 2. call emergency services and get an AED, 3. start chest compressions, 4. open the airway, and 5. give rescue breaths if trained.

Question 6

In a C-A-B cycle for a trained rescuer, how many chest compressions are usually given before rescue breaths for an adult?

Accepted Answer

A trained rescuer usually gives 30 chest compressions before giving 2 rescue breaths for an adult. This is often written as a 30:2 compression-to-breath ratio.

Question 7

A diagram shows a rescuer kneeling beside an adult with hands placed on the center of the chest. Which part of C-A-B does this picture show, and what should happen next in the sequence?

Accepted Answer

The picture shows Compressions, the C step. After compressions, the rescuer should open the Airway, then give Breathing support if trained and able.

Question 8

Choose the correct sequence: A. airway, breathing, compressions; B. compressions, airway, breathing; C. breathing, compressions, airway. Explain your choice.

Accepted Answer

The correct sequence is B. compressions, airway, breathing. This matches the C-A-B order used for CPR steps.

Question 9

A person trained in CPR begins with 30 compressions. What are the next two actions in the C-A-B sequence?

Accepted Answer

After 30 compressions, the rescuer should open the airway and then give 2 rescue breaths if trained and able. Then the cycle of compressions and breaths continues.

Question 10

Look at a flowchart with these boxes: Scene safe, Check response, Call emergency services and get AED, C, A, B. Fill in what C, A, and B mean.

Accepted Answer

C means chest compressions, A means open the airway, and B means rescue breathing. These steps happen after safety is checked, responsiveness is assessed, and emergency help is activated.

Question 11

Why should someone bring an AED as soon as possible while CPR is being performed?

Accepted Answer

An AED can check the heart rhythm and may deliver a shock if needed. CPR helps circulate blood, and the AED can provide an important treatment for certain cardiac arrest rhythms.

Question 12

Create a short memory phrase or sentence that helps you remember the C-A-B order. Then explain what each part means.

Accepted Answer

One possible memory phrase is Compress, Airway, Breathe. Compress means start chest compressions, Airway means open the airway, and Breathe means give rescue breaths if trained and able.
