To prevent an elderly client with Alzheimer's disease from choking on food, what intervention should a psychiatric technician implement?

The intervention that is most appropriate for preventing an elderly client with Alzheimer's disease from choking on food is to feed the client small bites. This process simplifies the swallowing mechanism, making it easier for the client to manage their food intake safely. Smaller bites reduce the risk of choking because they can be chewed and swallowed more effectively, allowing the client more time to process what they are eating.

Encouraging the client to eat slowly can be helpful, but it is less direct in addressing the choking risk than providing small bites. While oral hygiene is important for overall health and preventing aspiration pneumonia, it does not directly relate to preventing choking during meals. Removing all food from the client's sight would likely lead to increased anxiety or distress and would not solve the issue of choking during eating. Thus, providing small bites is the most effective intervention in this scenario to enhance safety during meals.
