Correct Answer: C

Rationale: The correct answer is C. Donepezil is a medication used for individuals with Alzheimer's disease. Its mechanism of action involves increasing acetylcholine levels by inhibiting its breakdown, which benefits cognitive function. The expected outcome of administering donepezil is a decrease in confusion and an improvement in mood due to the medication's impact on neurotransmitters. Choices A, B, and D are incorrect because donepezil does not primarily target muscle strength, urinary incontinence, or disease reversal; instead, it aims to slow down the progression of cognitive decline in Alzheimer's disease.

Correct Answer: C

Rationale: It is important to include information about the misuse of over-the-counter laxatives in older adults as they often misuse these medications, which can lead to dependency and other health issues. Option A is incorrect as laxatives can be effective in older adults when used appropriately. Option B is incorrect because not all laxatives are the same, they have different mechanisms of action and side effects. Option D is incorrect because laxatives can actually cause electrolyte imbalances like potassium depletion rather than retention.

Correct Answer: B

Rationale: The correct answer is to instruct the client to avoid taking oxycodone with alcohol. Mixing oxycodone with alcohol can lead to serious side effects, including respiratory depression. Taking the medication with meals may not always be necessary, and instructions about fluid intake to avoid constipation are important but not the priority when considering the immediate risks associated with oxycodone. While reporting signs of respiratory depression is crucial, preventing it by avoiding alcohol is key in the client's safety.

Correct Answer: A

Rationale: The correct answer is A: Drowsiness. Hydroxyzine is known to cause drowsiness, so clients should be advised to avoid activities like driving until they understand how the medication affects them. Choices B, C, and D are incorrect because dry mouth, nausea, and headache are not commonly associated with hydroxyzine use. It is crucial for the client to be aware of the potential drowsiness to ensure their safety and well-being while taking this medication.

Correct Answer: D

Rationale: Tiotropium is commonly used for COPD management.
