A nurse is assisting with planning care for a client who was admitted for reports of severe coughing, night sweats, and blood in the sputum. Which of the following precautions should the nurse take?

A. The medication reduces the rate at which the kidneys filter waste: This is incorrect as oxybutynin does not affect kidney function or the rate at which kidneys filter waste.
B. The medication decreases the sensitivity of the urethral sphincter: This is incorrect because oxybutynin primarily affects bladder muscle contraction, not the sensitivity of the urethral sphincter.
C. The medication prevents the bladder muscles from involuntarily contracting: This is correct as oxybutynin is an anticholinergic medication that reduces involuntary bladder contractions, leading to less frequent urination.
D. The medication blocks the nervous system impulse to produce urine: This is incorrect because oxybutynin works by blocking the action of acetylcholine in the bladder, not by blocking impulses to produce urine.

A. Participate in reminiscence therapy with the client: This is correct as reminiscence therapy, which involves discussing past experiences and memories, can help improve mood and cognitive function in clients with Alzheimer's disease.
B. Alternate the client's daily routine: Consistency is important for clients with Alzheimer's disease to reduce confusion and anxiety. Alternating the routine can be disorienting.
C. Keep the lights dimmed: Keeping the lights dimmed can contribute to confusion and disorientation. Adequate lighting is essential for safety and to help the client maintain a clear sense of time and space.
D. Raise the four side rails on the client's bed: Raising all four side rails can be considered a form of restraint and is not recommended. It can increase the risk of injury and does not address the client's needs appropriately.
