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: D

Rationale: The correct answer is D: Tremors. When a client is prescribed lithium for bipolar disorder, one common side effect to monitor for is tremors. Tremors are a known adverse effect of lithium therapy and should be monitored closely by healthcare providers. Choice A, dry mouth, is not typically associated with lithium use. Hair loss, as in choice B, is not a common side effect of lithium. Weight gain, as mentioned in choice C, can occur with some medications used to treat bipolar disorder, but it is not a prominent side effect of lithium specifically.

Correct Answer: D

Rationale: The correct answer is 'Nausea.' Nausea is a common side effect of metformin, especially when the medication is first started. It is essential for the client to report persistent or severe nausea to the healthcare provider for further evaluation and management. Weight gain (Choice A) is not a typical side effect of metformin; in fact, metformin is associated with weight loss or weight neutrality. Hypoglycemia (Choice B) is a potential side effect of some diabetes medications, but metformin does not typically cause hypoglycemia. Muscle pain (Choice C) is not a common side effect of metformin; it is more commonly associated with other medications like statins.

Correct Answer: A

Rationale: The correct answer is Agranulocytosis. Clozapine is known to potentially cause agranulocytosis, a serious condition characterized by a dangerously low white blood cell count. Monitoring white blood cell counts is crucial to detect this side effect early and prevent complications. Choices B, C, and D are incorrect because dry mouth, weight gain, and hypersalivation are not typically associated with clozapine use. While dry mouth can be a common side effect of some antipsychotic medications, it is not specifically linked to clozapine. Weight gain can occur with certain antipsychotics, but clozapine is more commonly associated with metabolic side effects. Hypersalivation is not a common side effect of clozapine.

Correct Answer: A

Rationale: The correct answer is weight gain. Rivaroxaban, an anticoagulant, may lead to weight gain as a side effect due to fluid retention. Dry mouth (choice B), dizziness (choice C), and headache (choice D) are not typically associated with rivaroxaban use. Therefore, monitoring for weight gain is crucial to detect and manage this potential side effect in the client.
