Abruptly withdrawing cortisone therapy
Poorly functioning adrenal glands
Lacking ACTH, related to the pituitary gland
Taking corticosteroids for many years
The Correct Answer is D
Rationale:

B. Poorly functioning adrenal glands cause Addison’s disease, not Cushing syndrome.
C. Lacking ACTH leads to secondary adrenal insufficiency, not Cushing syndrome.
D. Taking corticosteroids for many years can result in exogenous Cushing syndrome due to prolonged exposure to high cortisol levels, which mimic the effects of endogenous Cushing syndrome.

Correct Answer is D
Explanation
Rationale:
A. Vitamin D levels may be normal or low in hypoparathyroidism, but this value is within the expected range.
B. Calcium levels are expected to be low in hypoparathyroidism. A calcium level of 9.8 mg/dL is within the normal range (8.5 to 10.5 mg/dL), which is not consistent with hypoparathyroidism.
C. Magnesium levels are often normal or low in hypoparathyroidism, but this value is within the normal range.
D. Hypoparathyroidism results in hypocalcemia and hyperphosphatemia due to insufficient parathyroid hormone (PTH) secretion. A phosphate level of 5.7 mg/dL is elevated, which is consistent with this condition.
