AHA CPR Study Guide

What ratio for compressions to breaths should be used for 1-rescuer infant CPR?

• Give 5 compressions to 1 breath

• Give 15 compressions to 2 breaths

• Give 20 compressions to 2 breaths

• Give 30 compressions to 2 breaths

A 9-year-old child has suddenly collapsed. After confirming that the scene is safe, a single rescuer

determines that the child is in cardiac arrest, shouts for nearby help, and activates the emergency response

system by using his mobile device. He immediately begins performing high-quality CPR. Two additional

rescuers immediately arrive to assist in the resuscitation attempt. What actions should occur next to support a team-based resuscitation attempt?

• Two rescuers should operate the AED while the third rescuer gives breaths.

• One rescuer should give CPR while the other 2 wait for advanced life support to arrive.

• Two rescuers should alternate giving high-quality chest compressions.

• Two rescuers should alternate using the AED and giving breaths.

Why is defibrillation important?

• There is a 100% success rate.

• It is not important for cardiac arrest.

• It prevents rearrest from occurring.

• It can restore a regular cardiac rhythm.

A 53-year-old woman collapses while gardening. She is unresponsive, is not breathing, and does not have a

pulse. A neighbor, who is an emergency medical technician, rushes to her with an AED. When the AED arrives, what is the first step for using it?

• Press the Shock button

• Apply the pads to the chest

• Turn on the AED

• Clear the patient

A victim with a foreign-body airway obstruction becomes unresponsive. What is your first course of action?

• Start CPR, beginning with chest compressions

• Perform abdominal thrusts

• Roll the victim over and perform back blows

• Perform blind finger sweeps

While performing high-quality CPR on an adult, what action should you ensure is being accomplished?

• Allowing the chest to recoil to at least 1 inch

• Maintaining a compression rate of 90 to 120/min

• Placing hands on the upper third of the sternum

• Compressing to a depth of at least 2 inches

Which adult victim requires high-quality CPR?

• Has a pulse and is having trouble breathing

• Has no normal breathing and no pulse

• Has a strong pulse and is breathing

• Has normal breathing and has a pulse

Which characteristics of chest compressions in high-quality CPR are given to a child?

• At least one third the depth of the chest, approximately 2 inches (5 cm)

• At least one fourth the depth of the chest, approximately 1 1⁄2 inches (4 cm)

• At least one half the depth of the chest, approximately 3 inches (8 cm)

• At least two thirds the depth of the chest, approximately 4 inches (10 cm)

Why is allowing complete chest recoil important when performing high-quality CPR?

• The rate of chest compressions will increase.

• It will reduce the risk of rib fractures.

• The heart will adequately refill between compressions

• There will be a reduction in rescuer fatigue

When you are performing CPR on an unresponsive person whom you know is choking, what modification

should you incorporate?

• You should attempt a jaw thrust instead of a head tilt‒chin lift.

• You do not give breaths to an unresponsive choking victim.

• Each time you open the airway, you look for the obstructing object

• There are no modifications to CPR for an unresponsive choking victim.
