Step-by-step explanation:
The question assesses understanding of dietary changes needed to control hypertension. Of the options provided, the statement that most accurately indicates an understanding of the nurse's teaching about a heart-healthy diet is C) "I will eat four servings of unsalted nuts per week." This answer choice aligns with dietary recommendations to limit sodium intake and to include healthy fats in the diet, such as those found in nuts. It is important to limit sugar and salt intake, choose whole fruits over juices, limit saturated fats, and increase omega-3 fatty acids intake by eating foods like salmon, walnuts, flax seeds, and canola oil.
Eating habits such as consuming high amounts of fat and sodium can lead to high blood pressure and other health issues later in life. Therefore, making small changes, like including more unsalted nuts, can contribute to a healthier diet and better management of hypertension.
