After administering oral doses of calcitriol and calcium carbonate to a client with hypoparathyroidism, the nurse notes that the client's total calcium level is 14 mg/dL (3.5 mmol/L). Which action should the nurse implement?

Choice A reason: Administering both prescribed medications as scheduled is not the appropriate action in this situation. The client's total calcium level is above the normal range of 9 to 10.5 mg/dL (2.25 to 2.62 mmol/L), indicating hypercalcemia. Hypercalcemia is a serious condition that can cause nausea, vomiting, constipation, confusion, kidney stones, and cardiac arrhythmias. Giving more calcitriol and calcium carbonate would worsen the client's condition and increase the risk of complications.Choice B reason: Holding the calcium carbonate, but administering the calcitriol as scheduled is not the appropriate action in this situation. Calcium carbonate is a supplement that provides extra calcium to the body. Calcitriol is a synthetic form of vitamin D that helps the body absorb calcium from the intestines and kidneys. Both medications can increase the blood calcium level and cause hypercalcemia. The nurse should not give either medication without consulting the healthcare provider.Choice C reason: Holding both medications until contacting the healthcare provider is the best action in this situation. The nurse should recognize that the client's total calcium level is dangerously high and report it to the healthcare provider as soon as possible. The healthcare provider may order to stop or adjust the doses of calcitriol and calcium carbonate, and prescribe other treatments to lower the blood calcium level, such as intravenous fluids, diuretics, or bisphosphonates.Choice D reason: Holding the calcitriol, but administering the calcium carbonate as scheduled is not the appropriate action in this situation. Calcium carbonate is a supplement that provides extra calcium to the body. Giving more calcium carbonate to a client with hypercalcemia would increase the blood calcium level even more and cause more harm. The nurse should not give any medication that can raise the blood calcium level without consulting the healthcare provider.
