In summary, checking for hypomagnesemia is essential due to its direct impact on the client's hypertension and cardiac dysrhythmias.

Rationale: The correct answer is A: Confusion or delirium can be a defense against further stress. This is because providing new information slowly and in small amounts can help prevent overwhelming Mr. Reyes, who is already confused.

A: Assisting with activities of daily living is important but may not directly address the underlying issue of role strain. C: Teaching range-of-motion exercises is beneficial for physical well-being but does not directly address the emotional and psychological impact of role strain.
