Which statement about transdermal nitroglycerin patches is correct?

• A. They may be applied to any area of the body, regardless of hair distribution.
• B. Transdermal medications are applied to the skin by patch or disc and stay in place for 7 days.
• C. Removal of the old patch or disc prior to applying the new medication is recommended but not mandatory as all the medication has been absorbed from the old patch.
• D. Transdermal medications can be absorbed through the skin of the nurse's hands in the process of applying the medication to Mrs. Roman.

Answer: (D)

Transdermal nitroglycerin patches deliver drug through the skin, so there is a real risk of absorption by anyone handling the patch. This means the nurse’s hands can become exposed during application, which is why gloves and careful hand hygiene are essential. The patch should be removed from the patient before applying a new one to prevent unintended doubling of dose, and patches aren’t universally applied to any area, aren’t kept in place for a full week, and skin site considerations (like avoiding damaged skin or excessive hair) matter.
