Answer to Question 1

C
Donepezil suppresses appetite and causes weight loss. In a person who is underweight, the usual dosage can lead to toxicity. In addition, some Alzheimer's patients forget to eat and are already underweight. Weighing less than an ideal body weight increases the risk for many complications of old age and poor health.

Answer to Question 2

A
As for any drug delivered by transdermal patch, the old patch should be removed before applying the new one to prevent a drug overdose. The patches can irritate the skin and should not be replaced in the same position as the previous patch. Rotating sites prevents skin irritation and breakdown. Applying the patch closer to the brain does not increase brain absorption of the drug.
