Final answer:
The client with hypertension on nifedipine requires dietary education to avoid foods that may increase blood pressure, such as those high in sodium, caffeine, or fat.
Step-by-step explanation:
The client with hypertension is receiving nifedipine (Procardia XL), which is a calcium channel blocker used to lower blood pressure. A nurse needs to assess the patient's understanding of dietary restrictions, especially the intake of foods that may affect blood pressure. In the context of this medication and condition, the client would need additional education if they selected a breakfast menu high in sodium, caffeine, or fat—substances that can counteract the medication's effects and exacerbate hypertension.
