Answers Quiz 169 (July 25)
1. B
Explanation: HBS typically occurs after parathyroidectomy in patients with severe hyperparathyroidism, due to the abrupt drop in circulating PTH and consequent calcium uptake by bones.
2. C
Explanation: After parathyroidectomy, demineralised bones rapidly take up calcium, phosphates and magnesium, leading to a sharp decline in serum calcium levels — the hallmark of HBS.
3. D
Explanation: Alkaline phosphatase (ALP) is elevated due to high osteoblastic activity during bone healing and remineralization post-surgery. Serum calcium, phosphate, and magnesium are low.
4. C
Explanation: Chronic kidney disease (CKD) leads to secondary hyperparathyroidism, where PTH levels are chronically elevated. After surgery, these patients are high-risk for HBS due to bone hunger.
5. C
Explanation: Post-parathyroidectomy, calcium shifts into the bones due to the absence of PTH, which previously inhibited this uptake, resulting in hypocalcaemia.
