Answer and Explanation

The Correct Answer is D

A. Decreases the chance of peptic ulcer formation: Calcium carbonate is not an antiulcer medication.

B. Prevents constipation: Calcium carbonate can cause constipation, not prevent it.

C. Increases the tubular excretion of potassium: Calcium carbonate does not directly affect potassium excretion.

D. To lower phosphorus levels: Calcium carbonate is a phosphate binder that reduces phosphorus absorption from food. In chronic renal failure, phosphorus builds up due to decreased kidney excretion, leading to secondary hyperparathyroidism and bone disease (renal osteodystrophy).

C. Hypotension: While cooling can cause vasodilation and lower blood pressure, mild hypotension does not immediately necessitate stopping treatment.

D. Vomiting: Vomiting may be due to fever-related illness but is not a direct indicator that cooling should be stopped.
