Correct Answer is A
Explanation
(A) Include foods rich in potassium in the diet: Torsemide is a loop diuretic, which increases potassium excretion and may cause hypokalemia, requiring potassium supplementation.
(B) Increase calcium-rich foods: Torsemide primarily affects potassium, not calcium.
(C) Restrict fluid intake to 500 mL/day: Fluid restrictions may be necessary in severe heart failure, but 500 mL/day is too restrictive unless specifically indicated.
(D) Restrict foods rich in potassium in the diet: Torsemide causes potassium loss, not retention, so restricting potassium would worsen hypokalemia.
Correct Answer is D
Explanation
(A) Hypernatremia: PTH does not significantly affect sodium levels.
(B) Hyponatremia: PTH imbalance does not cause sodium depletion.
(C) Hypocalcemia: Hyperparathyroidism increases calcium levels, not decreases them.
(D) Hypercalcemia: Hyperparathyroidism causes excessive secretion of parathyroid hormone (PTH), which increases calcium release from bones, enhances calcium absorption in the intestines, and reduces calcium excretion by the kidneys, leading to hypercalcemia.
