Final answer:
A medical assistant should instruct a patient to apply the patch to clean, dry, and hairless skin, rotate application sites, not cut or trim the patch, and remove it immediately if any allergic reactions occur.
Step-by-step explanation:
A medical assistant should provide the following instructions to a patient regarding transdermal patch use and care:
- Apply the patch to clean, dry, and hairless skin. This ensures proper adhesion and effectiveness of the patch.
- Rotate application sites to avoid skin irritation. Constantly using the same site can lead to skin irritation or other complications.
- Do not cut or trim the patch. Cutting or trimming the patch can alter the dosage or release rate of the medication.
- Although not mentioned in the options, it is also important to remove the patch immediately if any allergic reactions occur to prevent further complications.
