EKG AcquisitionPregunta 50 de 100
A patient has a hairy chest and oily skin. What is the correct skin preparation before applying chest electrodes?
a.Apply the electrodes over the hair and press firmly
b.Clip the hair at each site, cleanse the skin with alcohol, let it dry, and gently abrade with a dry gauze
c.Shave the entire chest with a razor and apply lotion to soothe the skin
d.Wipe the chest with a povidone-iodine swab and apply electrodes while still wet
Explicación
Good skin prep means clipping excess hair only at the electrode sites, cleansing with alcohol to remove oils, allowing the skin to dry completely, and lightly abrading with dry gauze to reduce resistance. Applying electrodes over hair or wet skin causes poor contact and wandering baseline. Lotion insulates the skin, and full shaving with a razor is unnecessary and risks nicks that break the skin barrier.
