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: This is not an appropriate action for the nurse to take. Increasing the intake of saturated fats will worsen the side effects of orlistat, which inhibits the absorption of fats in the intestine. The client should be advised to follow a low-fat diet while taking orlistat.

Choice B reason: This is not an appropriate action for the nurse to take. Oily stools and flatus are common and expected side effects of orlistat, and they do not indicate a serious adverse reaction. The client does not need to stop taking the drug or contact her healthcare provider unless the symptoms are severe or persistent.

Choice C reason: This is not an appropriate action for the nurse to take. Obtaining a stool specimen to evaluate for occult blood and fat content is not necessary for a client taking orlistat. The presence of fat in the stool is normal and expected with orlistat, and there is no evidence of bleeding in the client's case.

Choice D reason: This is the appropriate action for the nurse to take. Asking the client to describe her dietary intake history for the last several days will help the nurse assess the client's compliance with the recommended low-fat diet and provide education and counseling as needed. The nurse can also monitor the client's weight loss progress and adjust the dosage of orlistat accordingly.

Choice A reason: Notifying the healthcare provider of the carbamazepine level is the most appropriate action for the nurse to take. Carbamazepine is an anticonvulsant drug that requires close monitoring of its serum levels to ensure therapeutic and safe effects. The normal reference range for carbamazepine is 4 to 12 mcg/mL or 16.9 to 50.8 mmol/L. A level of 84 mcg/L (35.6 mmol/L) is significantly higher than the upper limit and indicates toxicity. The nurse should report this finding to the prescriber immediately and hold the dose until further instructions.

Choice B reason: Administering the carbamazepine as prescribed is not the most appropriate action for the nurse to take. Giving the evening dose of carbamazepine when the morning level is already toxic can worsen the client's condition and cause serious adverse effects, such as confusion, drowsiness, ataxia, nystagmus, or coma. The nurse should not administer the medication without consulting the prescriber.

Choice C reason: Assessing the client for side effects of carbamazepine is an important action for the nurse to take, but it is not the most appropriate one. The nurse should assess the client for signs and symptoms of carbamazepine toxicity, such as nausea, vomiting, headache, blurred vision, or seizures. However, this action alone is not sufficient to address the problem. The nurse should also notify the prescriber and withhold the dose.

Choice D reason: Withholding this dose of the carbamazepine is a necessary action for the nurse to take, but it is not the most appropriate one. The nurse should not give the evening dose of carbamazepine when the morning level is already toxic, as this can increase the risk of complications. However, this action alone is not enough to resolve the issue. The nurse should also notify the prescriber and follow the appropriate interventions.
