In the Nursing Interventions for a Patient Receiving External Radiation

In the nursing interventions for a patient receiving external radiation treatments for a malignancy, the nurse must remember to

A) cleanse with soap and water the areas of entry or "ports" marked by the radiologist.
B) apply some form of ointment with a metallic base to the area of entry each time the patient goes for x-ray treatments.
C) instruct the patient to avoid irritating the "ports" by not lying on that part of the body and not wearing constricting clothing.
D) isolate the patient so he will not expose others to radiation.
