Correct Answer is D
Explanation
A. "Hypertension is the leading cause of death in people your age.": While hypertension is a significant risk factor for cardiovascular events and mortality, stating it as the leading cause of death without specific context or statistical data may not provide the most informative response to the client's question.
B. "Hypertension puts you at increased risk of type 1 diabetes and cancer in your age group.": Hypertension is primarily associated with cardiovascular risks such as stroke, heart disease, and kidney disease. While it can contribute to overall health risks, it is not typically linked directly to type 1 diabetes or cancer in the context of this client's question.
C. "Hypertension can cause you to develop dangerous blood clots in your legs that can migrate to your lungs.": While hypertension can contribute to cardiovascular complications such as deep vein thrombosis (DVT) and pulmonary embolism (PE), these are not the primary risks that are typically emphasized when discussing the importance of treating hypertension.
D. "Hypertension greatly increases your risk of stroke and heart disease.": This response is the most relevant and specific to the client's question. Hypertension is a major risk factor for stroke, heart disease (including heart attack and heart failure), and other cardiovascular complications. By treating hypertension and controlling blood pressure within recommended targets, the client can significantly reduce the risk of these serious and potentially life-threatening conditions.
Correct Answer is D
Explanation
A. "I will have canned chicken noodle soup with crackers and an apple for lunch": Canned soups are often high in sodium, and crackers can also contribute to sodium intake. This meal choice would not align with a low-sodium diet.
B. "I will have a ham and cheese sandwich for lunch": Processed meats like ham and cheese can be high in sodium, especially if they are not low-sodium options. This choice may not be suitable for a low-sodium diet unless specific low-sodium products are used.
C. "I will have a BLT and a side salad with cheese and croutons for lunch": Bacon, cheese, and croutons are all sources of sodium, so this meal would likely not be appropriate for a low-sodium diet unless modifications are made, such as using low-sodium bacon and limiting cheese and crouton amounts.
D. "I will have a baked potato with broiled chicken for dinner": This statement indicates an understanding of choosing low-sodium options. Baked potatoes and broiled chicken are generally low in sodium, especially if prepared without added salt or high-sodium seasonings. This choice aligns well with a low-sodium diet for someone with heart failure.
