A patient with abnormal sodium losses is receiving a house diet. To provide 1,600mg sodium daily, the nurse could supplement the patient's diet with:
- A. One beef cube and 8oz of tomato juice
- B. One beef cube and 16oz of tomato juice
- C. Four beef cubes and 8oz of tomato juice
- D. One beef cube and 12oz tomato juice
Correct Answer: D
Rationale: One beef cube typically contains about 800mg of sodium, and 8oz of tomato juice contains approximately 480mg of sodium. Therefore, to provide a total of 1,600mg of sodium daily, the nurse could supplement the patient's diet with one beef cube (800mg sodium) and 12oz of tomato juice (720mg sodium). This combination would effectively provide the required 1,600mg of sodium per day for the patient with abnormal sodium losses.
