Final answer:
The meal selection from the options that best indicates the client understands his new diet for managing blood pressure is Option C, because it includes low sodium and nutrient-rich foods such as whole grains and is free from unhealthy fats.
Step-by-step explanation:
The meal selection that indicates the client understands his new diet for managing hypertension is C) Oatmeal, apple juice, dry toast, and coffee. This meal is a better choice for regulating blood pressure because it is lower in sodium and higher in nutrients that support cardiovascular health, such as magnesium and potassium. Oatmeal is a whole grain that can help manage blood pressure, and while apple juice does contain natural sugars, it also provides some potassium. Dry toast without butter or margarine cuts down on sodium and unhealthy fats, and choosing coffee without milk or sugar minimizes the intake of saturated fat and added sugars.
Other foods that are thought to lower blood pressure include skim milk, spinach, beans, bananas, and dark chocolate. These foods supply essential nutrients like magnesium, calcium, and potassium which have a favorable effect on blood pressure regulation and can also reduce sodium retention. Those managing hypertension are encouraged to follow a diet similar to the DASH diet, which emphasizes the intake of these nutrients.
