Basic Life Support

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

• Start CPR, beginning with chest compressions

• Roll the victim over and perform back blows

• Perform abdominal thrusts

• Perform blind finger sweeps

How can rescuers ensure that they are providing effective breaths when using a bag-mask device?

• Observing the chest rise with each breath

• Always having oxygen attached to the bag

• Delivering breaths quickly and forcefully

• Allowing air to release around the mask

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 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)

• At least one fourth the depth of the chest, approximately 1½ inches (4 cm)

Which adult victim requires high-quality CPR?

• Has normal breathing and has a pulse

• Has no normal breathing and no pulse

• Has a pulse and is having trouble breathing

• Has a strong pulse and is breathing

You witness someone suddenly collapse. The person is unresponsive, you hear gasping sounds, and there is no pulse. You phone 9-1-1. What should you do next?

• Begin CPR; the gasps are not normal breathing

• Give rescue breaths only; the gasps are not normal breathing

• Monitor the patient; the gasps are considered normal breathing

• Begin CPR even though gasping is normal breathing

Use this scenario to answer the next 2 questions: 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. 6. When the AED arrives, what is the first step for using it?

• A. Apply the pads to the chest

• B. Clear the patient

• C. Turn on the AED

• D. Press the Shock button

Use this scenario to answer the next 2 questions: 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. 7. After the AED pads are attached to the person, the AED detects ventricular fibrillation. What is the next step when using an AED?

• Press the Shock button

• Follow the AED prompts

• Check for a carotid pulse

• Clear the patient

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

• Give 20 compressions to 2 breaths

• Give 5 compressions to 1 breath

• Give 15 compressions to 2 breaths

• Give 30 compressions to 2 breaths

What special circumstance should a rescuer consider when using an AED?

• AEDs can only be used while a person is submerged in water.

• On a hairy chest, the pads may not stick and may fail to deliver a shock.

• They should never remove a transdermal medication patch before applying AED pads.

• They should never use an AED on someone with an implanted pacemaker.

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

• There will be a reduction of rescuer fatigue.

• The rate of chest compressions will increase.

• The heart will adequately refill between compressions.

• It will reduce the risk of rib fractures.
