Question

question 20 (mandatory) (1 point)
lab work on a 62 - year - old male patient reveals elevated alkaline phosphatase, elevated calcium, and high phosphorus. which of the following is the most likely diagnosis?
a) pagets disease
b) bone destruction
c) hypoparathyroidism
d) hyperparathyroidism

Explanation:

• Paget's disease: Characterized by elevated alkaline phosphatase, normal calcium and phosphorus levels.
• Bone destruction: Can cause elevated alkaline phosphatase, but calcium and phosphorus levels vary depending on the cause.
• Hypoparathyroidism: Results in low calcium and high phosphorus levels, with normal or low alkaline phosphatase.
• Hyperparathyroidism: Leads to elevated calcium, normal or low phosphorus (in primary hyperparathyroidism, phosphorus is often low; in secondary hyperparathyroidism due to chronic kidney disease, phosphorus can be high as in this case as kidney may not excrete phosphorus well), and elevated alkaline phosphatase (due to bone turnover).

Answer:

d) Hyperparathyroidism
