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: Providing a heating pad to the client may provide some temporary relief, but it does not address the underlying cause of the neck discomfort, which is likely due to extrapyramidal side effects (EPS) of the antipsychotic medication.

Choice B reason: Obtaining a prescription for physical therapy services may be beneficial for the client's overall health and well-being, but it is not the best intervention for the acute problem of neck discomfort. Physical therapy may also require a referral and a waiting period, which would delay the relief for the client.

Choice C reason: Giving a PRN prescription for benztropine is the best intervention for the nurse to implement, as benztropine is an anticholinergic medication that can counteract the EPS of the antipsychotic medication. Benztropine can reduce the muscle stiffness and spasms that cause the neck discomfort.

Choice D reason: Obtaining an extra pillow for the client to use at night may help the client sleep better, but it does not address the neck discomfort during the day. It also does not treat the EPS of the antipsychotic medication, which may worsen over time.

Choice A reason: Employed as a construction worker is not the most important assessment finding for the nurse to address. Although the client's occupation may expose them to moist and warm environments that can promote fungal growth, it is not directly related to the administration of terbinafine HCL. The nurse should advise the client to wear breathable shoes and socks and keep the feet dry and clean, but it is not a priority.

Choice B reason: Reported history of alcoholism is the most important assessment finding for the nurse to address. Terbinafine HCL can cause hepatotoxicity, especially in clients with pre-existing liver disease or who consume alcohol regularly. The nurse should assess the client's liver function tests and alcohol intake before starting the medication and inform the prescriber accordingly. The nurse should also monitor the client for signs and symptoms of liver damage, such as jaundice, abdominal pain, nausea, or fatigue.

Choice C reason: White blood cell count of 8,500/mm3 (8.5 x 10^9/L) is not the most important assessment finding for the nurse to address. This value is within the normal reference range of 5,000 to 10,000/mm3 (5 to 10 x 10^9/L) and does not indicate any infection or inflammation. The nurse should check the client's baseline blood counts before starting the medication, but it is not a priority.

Choice D reason: Toenails appear thick and yellow is not the most important assessment finding for the nurse to address. This is a typical manifestation of a fungal toenail infection, which is the indication for terbinafine HCL. The nurse should expect the toenails to improve in appearance and texture after the completion of the treatment, which may take several weeks or months. The nurse should educate the client about the expected outcomes and adherence to the medication regimen, but it is not a priority.
