Correct answer

Emphasis on fruits, vegetables, whole grains, and low-fat dairy; limited saturated fat, sodium (<2,300 mg/day ideally <1,500 mg/day), and added sugars; adequate potassium, calcium, and magnesium

  1. A High protein, low carbohydrate intake
  2. B Emphasis on fruits, vegetables, whole grains, and low-fat dairy; limited saturated fat, sodium (<2,300 mg/day ideally <1,500 mg/day), and added sugars; adequate potassium, calcium, and magnesium
  3. C Unlimited fat intake if it comes from animal sources
  4. D Eliminate all carbohydrates

Why this is the answer

DASH DIET (Dietary Approaches to Stop Hypertension): Developed specifically to reduce blood pressure. KEY COMPONENTS: Fruits: 4-5 servings/day; Vegetables: 4-5 servings/day; Whole grains: 6-8 servings/day; Low-fat dairy: 2-3 servings/day; Lean meats, poultry, fish: ≤6 oz/day; Nuts, seeds, legumes: 4-5 servings/week; Fats/oils: 2-3 servings/day; Sweets: ≤5 per week; SODIUM: Standard DASH = <2,300 mg/day; Lower-sodium DASH = <1,500 mg/day (recommended for HTN, diabetes, CKD, age 51+, Black adults); EVIDENCE: Reduces systolic BP by 8-14 mmHg; comparable to single antihypertensive medication; NURSING EDUCATION: Focus on what to ADD (produce, whole grains) before restricting — positive framing improves adherence.
