Question

what does the term \full recoil\ mean in cpr?

a. compressing the chest rapidly

b. stopping between compressions

c. releasing compressions after 10 pushes

d. allowing the chest to rise fully between compressions

what happens if you do not allow the aed to analyze the heart rhythm?

a. the aed will turn off automatically

b. the aed will continue analyzing until a shock is given

c. the aed will deliver an immediate shock

d. the aed may not deliver an accurate diagnosis

Explanation:

First Question (About "full recoil" in CPR)

To determine the meaning of "full recoil" in CPR, we analyze each option:

• Option a: Compressing the chest rapidly refers to the rate of compressions, not recoil. Eliminate a.
• Option b: Stopping between compressions is not what recoil means. Recoil is about the chest's movement, not just stopping. Eliminate b.
• Option c: Releasing compressions after 10 pushes is about a cycle of compressions, not the definition of recoil. Eliminate c.
• Option d: Full recoil in CPR is defined as allowing the chest to rise fully between compressions, so that the heart can refill with blood. This matches the definition.

To answer this, we analyze each option:

• Option a: AEDs do not turn off automatically just because analysis is interrupted. Eliminate a.
• Option b: AEDs do not continue analyzing indefinitely if not allowed to complete; they need proper analysis time. Eliminate b.
• Option c: AEDs only deliver shocks after analyzing and determining a shockable rhythm. Without analysis, it won't deliver an immediate shock. Eliminate c.
• Option d: If an AED is not allowed to analyze the heart rhythm properly, it may not be able to accurately diagnose if a shock is needed, leading to inaccurate results. This makes sense.

Answer:

d. Allowing the chest to rise fully between compressions
