Forgive me if this is a stupid question. I'm a student in my final semester of a BSN program and doing my preceptorship on a cardiac stepdown unit. We routinely have pts s/p cabg who have temporary, external pacing wires, which I understand. However, most of them are not actually being paced. If a patient is not connected to an external pacemaker, then what is the big hub ub about handling wires with gloves (beyond infxn ctrl), wrapping and isolating? I don't understand how one can be shocked by something that is not hooked up to any electricity...Please enlighten me.
