In performing CPR on an infant:
a. place two fingers on the sternum just beneath an imaginary line between the nipples, and make compressions that are approximately one-third the depth of the chest.
b. stop to check for a pulse after administering about 100 compressions.
c. place the heel of one hand on the sternum just above an imaginary line between the nipples, and make compressions that are about inch deep.
d. check the carotid artery for a pulse before beginning compressions.
Question 2One complication of an acute myocardial infarction may be cardiogenic shock. Based on your training, you would define cardiogenic shock as a(n):
a. condition whereby tissues of the body are oxygen deprived due to the heart's inability to adequately pump blood.
b. absolute or relative shortage of blood supply to a tissue due to a blood clot.
c. abrupt cessation of the regular electrical activity of the heart.
d. acute illness in which the cardiac muscle does not get enough oxygen.
Question 3You are out shopping when a middle-aged man suddenly falls to the ground. You quickly run to assist him and note that he is not breathing and does not have a carotid pulse. You begin CPR because you know that prompt intervention with an AED is needed. Which of the following statements is not a reason that prompt intervention with an AED is needed?
a. Since AED was first used by trained and lay rescuers, patient survival from sudden cardiac arrest has doubled.
b. Two common arrhythmias that are associated with sudden cardiac deathventricular fibrillation and pulseless ventricular tachycardiacan respond to AED use.
c. Asystole, which can accompany an acute MI, is often reversed by the use of an AED.
d. Studies show that after 10 minutes of pulseless cardiac arrest due to V-fib or V-tach, the heart is less responsive to electrical stimulation.
