An elderly client diagnosed with delirium is being treated with antipsychotic medication. Which side effect should the nurse monitor for in this client?
Correct Answer: C
Rationale: The correct side effect that the nurse should monitor for in an elderly client diagnosed with delirium and treated with antipsychotic medication is orthostatic hypotension. Antipsychotic medications can lead to a drop in blood pressure upon standing, particularly in elderly individuals. Akathisia (choice A) refers to a movement disorder characterized by a feeling of inner restlessness and a compelling need to be in constant motion, which can be a side effect of antipsychotic medications but is not specific to elderly clients with delirium. Hallucinations (choice B) are sensory perceptions that appear real but are created by the mind, and while they can be associated with certain conditions or medications, they are not a common side effect of antipsychotic medications in elderly clients with delirium. Drowsiness (choice D) is a general CNS depressant effect that can occur with antipsychotic medications but is not the specific side effect that the nurse should be monitoring for in this case.
