Question

early defibrillation is a link in the adult chain of survival. why is this important to survival? it provides normal respiration. it prevents respiratory arrest. it prevents cardiac arrest. it eliminates the abnormal heart rhythm. 16 multiple choice 0/1 what special circumstance should a rescuer consider when using an aed? they should never remove a transdermal medication patch before applying aed pads. on a hairy chest, the pads may not stick and may fail to deliver a shock. they should never use an aed on someone with an implanted pacemaker. aeds can only be used while a person is submerged in water.

Explanation:

• First question: Defibrillation is about the heart. Early defibrillation aims to correct abnormal heart rhythms (like ventricular fibrillation). It doesn't directly provide normal respiration (that's ventilation's role), and it occurs after cardiac arrest (so it can't prevent it). Respiratory arrest is a different issue (lack of breathing).
• Second question: Transdermal patches should be removed (they can block pad contact). AEDs can be used on people with pacemakers (keep pads away from it). AEDs shouldn't be used on submerged people. On a hairy chest, pads may not stick well (hairs can create a barrier), which can affect shock delivery.

Answer:

• First question: It eliminates the abnormal heart rhythm.
• Second question: On a hairy chest, the pads may not stick and may fail to deliver a shock.
