Which intervention is most appropriate for a nurse to implement for a patient experiencing Lewy body dementia?

Rationale: A. Patients with Lewy body dementia (LBD) are extremely sensitive to antipsychotic medications. Even low doses can cause severe adverse reactions, including worsening parkinsonism, neuroleptic malignant syndrome, or sudden decline. Therefore, antipsychotics are generally avoided unless absolutely necessary and with extreme caution. B. Sedatives, such as benzodiazepines, can worsen confusion, increase fall risk, and exacerbate cognitive impairment in LBD. They are not recommended as a first-line intervention for behavioral management in these patients. C. Cholinesterase inhibitors (e.g., rivastigmine, donepezil) are considered first-line pharmacologic treatment for cognitive impairment in Lewy body dementia. They can improve cognition, attention, and sometimes reduce visual hallucinations, making them the most appropriate intervention for managing LBD symptoms safely. D. While structured routines can help reduce confusion and agitation in dementia patients, a strict timed schedule is not the primary intervention for LBD. Flexibility is often necessary to accommodate fluctuating cognition and avoid frustration. Structured schedules may be used as a complementary non-pharmacologic strategy but are not the most critical intervention.
