A. The recommended sodium intake for individuals with hypertension is typically less than 2,300 mg per day, so a goal of 3,000 mg is too high.
B. For individuals with hypertension, it is recommended to limit alcohol consumption to 1 drink per day for women and 2 drinks per day for men, so 3 drinks is excessive.
C. Planning to have potassium blood levels checked when taking thiazide diuretics is important because these medications can lead to hypokalemia (low potassium levels), making this the correct response.
D. Setting a goal body weight within 25% of ideal body weight is not a standard recommendation; weight management should focus on achieving a healthy weight, rather than a specific percentage of ideal body weight.
