What is the purpose of calcium supplements for a patient with DiGeorge syndrome?

Calcium supplements for a patient with DiGeorge syndrome primarily serve to prevent tetany and seizures. DiGeorge syndrome is characterized by a deficiency in the parathyroid glands due to a developmental defect. This deficiency can lead to hypoparathyroidism, resulting in low calcium levels in the blood (hypocalcemia). When calcium levels drop too low, it can trigger muscle spasms (tetany) and, in more severe cases, seizures. Supplementing with calcium helps to ensure that the body maintains adequate levels of this essential mineral, thereby mitigating the risk of these serious complications.

While the other options touch on aspects related to immune function and infection management, they do not directly correlate with the primary purpose of calcium in this context. Calcium supplementation does not provide immunity or treat existing infections, nor does it prevent infections; rather, its role in managing symptoms and complications from the hypocalcemia associated with DiGeorge syndrome is crucial for patient care.
