EKGQuestion 82 of 100
To obtain a clear EKG tracing, how should the technician prepare the skin before applying electrodes?
a.Apply electrodes over lotion for better adhesion
b.Clean the site, and if needed clip excess hair and lightly abrade dry skin so electrodes adhere well
c.Place electrodes directly over thick chest hair
d.Wet the skin thoroughly before applying electrodes
