Answers Quiz- 170 (July 26)

1. C

Explanation: HBS causes hypocalcemia, not hypercalcemia. Bradycardia from hypercalcemia is not expected. Tetany, paresthesia, and muscle cramps are typical.

2. B

Explanation: Chronic high PTH leads to osteitis fibrosa cystica, characterized by bone weakening, resorption, and fibrous tissue replacement.

3. B

Explanation: Preoperative identification and correction of vitamin D and calcium deficiency reduces the risk of postoperative HBS in vulnerable patients.

4. C

Explanation: Calcitriol, the active form of vitamin D, is used to rapidly correct hypocalcemia by increasing intestinal calcium absorption and reducing PTH levels.

5. A

Explanation: In HBS, alkaline phosphatase is elevated due to increased bone formation. In contrast, hypoparathyroidism shows low PTH but normal ALP levels.
