Prior to administering an oral dose of methylprednisolone, the nurse determines the client's serum total calcium level is 5.5 mg/dL (1.4 mmol/L). Which action is most important for the nurse to take?Reference Range: Total Calcium (9 to 10.4 mg/dL (2.3 to 2.6 mmol/L))

Choice A reason: A serum total calcium level of 5.5 mg/dL is significantly below the normal range and indicates hypocalcemia, which can lead to serious symptoms such as muscle spasms, tingling, and cardiac issues. The nurse should notify the healthcare provider immediately to address this critical electrolyte imbalance.Choice B reason: Tapering the drug dose per protocol may be necessary for long-term corticosteroid use, but this action is not directly related to the immediate concern of hypocalcemia. The priority is to address the dangerously low calcium level.Choice C reason: Teaching the client about foods high in calcium is important for managing long-term calcium levels, but it does not address the immediate risk posed by severe hypocalcemia. The nurse must first ensure that the healthcare provider is informed.Choice D reason: Administering the medication with a glass of milk can help with calcium intake, but it is not a sufficient response to a critical calcium deficiency. Immediate medical intervention is required to correct the severe hypocalcemia.
