The nurse is caring for a client with hypocalcemia. The nurse expects that in addition to calcium supplements, the physician will order:

Rationale: A. Alendronate: Alendronate is a bisphosphonate that inhibits bone resorption to treat osteoporosis. It does not raise serum calcium levels directly and is not indicated for acute management of hypocalcemia. B. Phosphorus binder: Phosphate binders are used to reduce elevated serum phosphate, particularly in chronic kidney disease. While phosphate and calcium levels are related, phosphate binders do not directly correct hypocalcemia and would not be the primary treatment unless hyperphosphatemia is present. C. Vitamin D: Vitamin D enhances intestinal absorption of calcium and supports bone mineralization. In hypocalcemia, supplementation with vitamin D (such as calcitriol) is often ordered alongside calcium to optimize calcium uptake and maintain adequate serum levels. D. Potassium chloride: Potassium chloride is used to correct hypokalemia or maintain normal potassium levels. It has no effect on calcium metabolism or absorption and is not relevant in the management of hypocalcemia.
