Correct Answer: C

Rationale: Changing preferences isn’t delirium-specific. Suspecting poison suggests delusion, not necessarily delirium. Confusion about recent events, like family visits, indicates delirium’s hallmark disorientation. Requesting blankets in a warm room may reflect sensory issues, not delirium directly.

Correct Answer: C

Rationale: Risperidone is an antipsychotic used for behavioral issues in dementia, not cognitive decline. Alprazolam is an anxiolytic, not indicated for Alzheimer’s cognitive symptoms. Donepezil is a cholinesterase inhibitor commonly prescribed to improve cognition and slow symptom progression in moderate Alzheimer’s. Haloperidol, an antipsychotic, treats agitation but doesn’t enhance cognition and has higher side effect risks.

Correct Answer: A

Rationale: SSRIs are often the first-line treatment for depression in older adults due to their favorable side effect profile, including lower risk of sedation and falls compared to other options. Benzodiazepines are not typically used for depression as they treat anxiety and can increase the risk of falls and confusion in older adults. Hypnotics are used for sleep issues, not as antidepressants, and don’t address the core symptoms of depression. Monoamine oxidase inhibitors are effective but often reserved for cases where other treatments fail due to their dietary restrictions and potential for serious side effects.

Correct Answer: B

Rationale: Preference changes aren’t delirium-specific. Suspecting poison indicates delusional confusion, a delirium sign. Blankets in warmth suggest sensory issues, not delirium. Time confusion fits delirium, but poisoning suspicion is more acute.

Correct Answer: B

Rationale: Exercise benefits Alzheimer’s clients, reducing fall risk with supervision. Frequent orientation maintains cognition and security. Large groups overwhelm due to cognitive limits. Over-stimulation causes confusion; moderate stimulation is better.
