The nurse is providing instructions about a client's new medications. How should the nurse explain the purpose of probenecid, a uricosuric drug?

Choice A rationale: This is not appropriate because the client's elevated calcium level requires immediate attention and further assessment by the healthcare provider before administering any medications that may further raise calcium levels.

Choice B rationale: The client's total calcium level is significantly elevated, which may indicate hypercalcemia. Given the reference range for total calcium in adults is 9 to 10.5 mg/dL (2.25 to 2.62 mmol/L), a calcium level of 14 mg/dL (3.5 mmol/L) is abnormally high. Both calcitriol (active form of vitamin D) and calcium carbonate (calcium supplement) can increase calcium levels in the body. Before administering any medication, the nurse should hold both calcitriol and calcium carbonate and notify the healthcare provider of the elevated calcium level. The healthcare provider will determine the appropriate course of action and may adjust the dosage or temporarily discontinue the medications to prevent further complications related to hypercalcemia.

Choice C rationale: Holding calcium carbonate is a step in the right direction, but given the significant elevation of total calcium, it is best to hold both medications and consult the healthcare provider.

Choice D rationale: Holding calcitriol is a step in the right direction, but both medications should be held to prevent exacerbation of hypercalcemia until further instructions are received from the healthcare provider.

Choice A rationale: This option is not appropriate as increasing saturated fat intake would exacerbate the oily stool and flatus symptoms caused by orlistat. Orlistat is specifically designed to reduce fat absorption, and increasing fat intake would be counterproductive and may worsen the side effects.

Choice B rationale: Asking a client to describe their dietary intake history is a standard practice in nutritional assessment. It provides a baseline for understanding current eating habits and identifying areas for improvement.

Choice C rationale: Advising a client to stop taking medication should only be done by a qualified healthcare provider who has full knowledge of the client's health history and current medications.

Choice D rationale: While obtaining a stool specimen for evaluation might be relevant in some situations, it is not the priority in this case. The oily stools and flatus are most likely related to the side effects of orlistat and do not typically require stool testing for confirmation. The more immediate action would be to address the symptoms by advising the client to stop taking the medication and contact her healthcare provider for further guidance.
