When the Nurse Is Assisting a Male Patient to Shave

When the nurse is assisting a male patient to shave his face, it is most important for her to:

A) practice on a male friend or relative before trying it on a patient.
B) have the patient shave first before any other hygiene measures are performed.
C) be sure the patient knows to draw the razor in the direction the hair grows.
D) check whether a safety razor can be used or whether it is contraindicated.
