A nurse is teaching a client who is on a low-sodium diet. Which of the following instructions should the nurse provide?

Choice A reason: Canned soups are high in sodium (often 800-1000 mg per serving), exacerbating hypertension by increasing extracellular fluid volume and vascular resistance. Limiting to two servings still exceeds low-sodium diet goals (1500-2300 mg/day), making this ineffective for controlling sodium intake and managing cardiovascular health. Choice B reason: Processed meats (e.g., bacon, deli meats) are high in sodium and preservatives, increasing blood pressure by promoting fluid retention and vasoconstriction. Fresh meats are naturally low in sodium, making them preferable for a low-sodium diet to reduce cardiovascular strain and maintain electrolyte balance. Choice C reason: Reading food labels allows identification of sodium content, critical for a low-sodium diet (1500-2300 mg/day). Sodium affects fluid balance and blood pressure via renin-angiotensin-aldosterone system activation. Label reading empowers patients to choose low-sodium options, preventing hypertension and supporting cardiovascular health effectively. Choice D reason: Using table salt sparingly is insufficient, as most dietary sodium comes from processed foods, not added salt. Sodium chloride increases extracellular fluid, elevating blood pressure. Comprehensive sodium reduction requires avoiding high-sodium foods, not just limiting table salt, to effectively manage a low-sodium diet.
