Question

which step is one of the universal steps for operating an aed? placing the pads on the victims bare chest shaving the victims hairy chest removing the victim from water finding the victims implanted pacemaker

Explanation:

When operating an AED, the pads are needed to be placed on the victim's bare chest for proper electrical contact. Shaving a hairy chest (if not extremely necessary) may waste time, removing from water (if not in water - related emergency context) is not a universal step, and finding an implanted pacemaker (not a step in normal AED operation - just avoid placing pads over it if known).

Answer:

Placing the pads on the victim's bare chest
