Question

chronic renal failure will result in: primary hypoparathyroidism secondary hyperparathyroidism primary hyperparathyroidism primary hyperthyroidism

Explanation:

Chronic renal failure leads to impaired phosphate excretion and decreased activation of vitamin D, which causes hypocalcemia. This hypocalcemia stimulates the parathyroid glands to secrete more parathyroid hormone (PTH), resulting in secondary hyperparathyroidism. Primary hypoparathyroidism is due to parathyroid gland issues, primary hyperparathyroidism is from parathyroid gland overactivity (not renal - related), and primary hyperthyroidism is about the thyroid gland, not related to renal failure.

Answer:

B. Secondary Hyperparathyroidism
