BLS Practice

1. 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 1 1/2 inches (4 cm)

Which adult victim requires high-quality CPR?

• Has normal breathing and 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.

When the AED arrives, what is the first step for using it?

• Apply the pads to the chest

• Clear the patient

• Turn on the AED

• Press the shock button

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
