Final answer:
The nurse should recommend a low-fat, low-sodium diet to manage cardiovascular risk factors of hyperlipidemia and hypertension.
Step-by-step explanation:
The best response by the nurse would be B) "A low-fat, low-sodium diet would be beneficial."
For managing cardiovascular risk factors of hyperlipidemia and hypertension, it is important to follow a diet that is low in both fat and sodium. Consuming excess dietary lipids, especially saturated fatty acids and cholesterol, can increase the risk for cardiovascular disease. Additionally, reducing salt intake is recommended to help lower blood pressure. Therefore, a low-fat, low-sodium diet would be the most suitable for the client's condition.
