Chapter 13 - BLS Resuscitation

Question 1

A 60-year-old man is found to be unresponsive, pulseless, and apneic. You should:

A. begin CPR until an AED is available

B. determine if he has a valid living will

C. withhold CPR until he is defibrillated

D. start CPR and transport immediately

Answer 1

A. begin CPR until an AED is available

Question 2

While rescuer one is finishing his or her fifth cycle of 30 compressions, rescuer two should:

A. assess for a carotid pulse for 15 seconds

B. move to the opposite side of the patient’s chest

C. give two rescue breaths and prepare to start compressions

D. suction the patient’s mouth and give two more ventilations

Answer 2

B. move to the opposite side of the patient’s chest

Question 3

The impedance threshold device (ITD) may improve circulation during active compression-decompression CPR by:

A. maintaining increased intrathoracic pressure during the downward stroke of each chest compression, which forces more blood from both of the ventricles.

B. limiting the amount of air that enters the lungs during the recoil phase between chest compressions, which results in negative intrathoracic pressure and improved cardiac filling.

C. drawing all of the air out of the lungs in between chest compressions, which causes positive intrathoracic pressure and a reduction of blood return to the right side of the heart.

D. maximizing the amount of air in the lungs following chest recoil, which hyperinflates the lungs and forces more blood from the ventricle during each compression.

Answer 3

B. limiting the amount of air that enters the lungs during the recoil phase between chest compressions, which results in negative intrathoracic pressure and improved cardiac filling.
