A nurse is caring for a client with hyperparathyroidism who has a serum calcium level of 13 mg/dL. Which medication should the nurse prepare to administer?

In the context of hyperparathyroidism, a serum calcium level of 13 mg/dL indicates hypercalcemia, which is characterized by elevated calcium levels in the blood. The correct choice, Calcitonin (Miacalcin), plays a vital role in managing hypercalcemia. This medication works by inhibiting osteoclast activity, which decreases the release of calcium from bones into the bloodstream, thus lowering serum calcium levels. Additionally, it promotes renal excretion of calcium, further aiding in the reduction of hypercalcemia.

In cases of hyperparathyroidism, where parathyroid hormone secretion leads to increased calcium levels, administering calcitonin can help counteract these effects effectively. The use of this medication allows for a more immediate reduction in elevated calcium levels, which is crucial for preventing complications such as cardiac disturbances and neurological issues that can arise with hypercalcemia.

Other choices, while relevant in different contexts, would not be appropriate in this situation. Calcium gluconate is used to increase serum calcium levels, making it unsuitable for hypercalcemia treatment. Vitamin D aids in calcium absorption and could exacerbate the condition in patients with hyperparathyroidism. Bisphosphonates are typically used to manage conditions like osteoporosis and can help in
