Prior to administering an oral dose of methylprednisolone, the nurse determines the clientÔÇÖs serum total calcium level is 5.5 mg/dL (1.375 mmol/L). What action is most important for the nurse to take?

Rationale for Correct Answer (C): The nurse should notify the healthcare provider of the low serum calcium level (hypocalcemia) before administering methylprednisolone. Corticosteroids like methylprednisolone can further lower calcium levels, leading to serious complications such as tetany or cardiac arrhythmias. The healthcare provider may need to adjust the medication regimen or provide calcium supplementation.

Summary of Incorrect Choices:
A: Teaching about high calcium foods is not the priority when the client already has low serum calcium levels.
B: Tapering the drug dose per protocol may not be sufficient to address the immediate risk of hypocalcemia.
D: Administering the medication with milk does not address the underlying issue of hypocalcemia and may not prevent complications.
E, F, G: No information provided.
