In which of the following clinical situations is the normally high resistance of the skin bypassed?
I.in patients with external pacemaker wires
II.in patients with saline-filled catheters
III.in patients with intact, dry skin

Question

Quizplus · Accepted Answer

In patients with external pacemaker wires and saline-filled catheters, the skin resistance is bypassed due to direct contact between the wires/catheters and tissues/fluids within the body.  Intact, dry skin presents a high resistance to current flow, which is only bypassed in situations where there is direct contact between the tissue/fluid and an electrically conductive material such as metal or saline solution.
