Question: Which instruction makes the MOST sense to give a patient who is about to receive a 12-lead EKG? "You don't need to undress for this procedure. I can put the electrodes under your shirt." "Please undress completely. I'll start putting on the electrodes in a few minutes." "Please undress to the waist and put on this gown with the opening in back." "Please undress to the waist and put on this gown with the opening in front."
