A client with a history of dementia has become increasingly confused at night and is picking at an abdominal surgical dressing and the tape securing the intravenous (IV) line. The abdominal dressing is no longer occlusive, and the IV insertion site is pink. Which intervention should the nurse implement?

Rationale for A: Redressing the abdominal incision is crucial as the dressing is no longer occlusive, which could lead to infection. An intact dressing also prevents the client from picking at the site, which could cause further harm or delay healing. Rationale for B: Leaving the lights on might help with visual perception for a client with dementia, but it does not directly address the immediate risk of infection or the client's interference with the dressing. Rationale for C: Applying restraints could be considered for a client who is at risk of harming themselves, but this should be a last resort after other interventions have been tried due to the potential for physical and psychological harm. Rationale for D: Replacing the IV site with a smaller gauge is not indicated by the pink insertion site alone and does not address the client's confusion or behavior towards the dressing.
