Final answer:
Transdermal patches should be avoided in hairy areas, bony prominences, and areas with scars or tattoos.
Step-by-step explanation:
When placing transdermal patches, it is important to avoid certain locations. These include hairy areas, bony prominences, and areas with scars or tattoos.
Hairy areas should be avoided because the hair can interfere with the adherence of the patch, making it less effective. Bony prominences, such as the knees or elbows, can cause discomfort or irritation when pressed against the patch. Areas with scars or tattoos may also have altered skin integrity, which can affect the absorption of the medication.
Therefore, the correct answer is d) All of the above.
