A nurse is planning care for a client who has acute delirium. Which of the following instructions should the nurse include in the plan?

A. Assign the client to a different caregiver each shift: This is not ideal for a client with acute delirium. Consistency in caregivers is important to reduce confusion and help the client feel more secure in a familiar environment. B. Teach the client assertive techniques: Assertiveness training is more appropriate for clients with anxiety or communication difficulties, not for those with acute delirium. In delirium, the priority is managing cognitive function and safety. C. Refute the client's perception of visual hallucinations: Refuting hallucinations can cause frustration and worsen the client's confusion. It’s better to acknowledge the hallucinations calmly without validating them, offering reassurance instead of confrontation. D. Reinforce the client's orientation with a calendar: This is an appropriate intervention. Using a calendar, clock, and other orientation tools helps reinforce reality and can reduce confusion in clients with delirium, aiding in their cognitive stabilization.
