Correct Answer is A

Explanation

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.

A. Takes metformin hydrochloride for type 2 diabetes mellitus. B. Metal hip prosthesis was placed twenty years ago. C. CT scan was performed six months earlier. D. Report of client's sobriety for the last five years.

Correct Answer is A

Explanation

Choice A reason: Metformin is contraindicated with iodinated contrast due to the risk of lactic acidosis, a rare but serious complication. The nurse needs to follow up and likely hold the metformin before and after the CT scan to reduce this risk.

Choice B reason: A metal hip prosthesis may interfere with imaging, but this information is not as critical as the potential risk posed by metformin. The radiology team should be informed, but it does not require immediate follow-up in the same way as medication contraindications.

Choice C reason: A CT scan performed six months earlier does not contraindicate a repeat scan, although it may be relevant to the clinical history. The main concern is to ensure there are no contraindications to the contrast agent.

Choice D reason: The client's sobriety report does not affect the administration of a CT scan with contrast. This information is not directly relevant to the immediate safety and effectiveness of the imaging procedure.
