The nurse is administering muscle relaxant baclofen by mouth (PO) to a client diagnosed with multiple sclerosis. Which intervention is the most important for the nurse to implement?

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.

Choice A reason: This is not the first action for the nurse to take. Applying oxygen face mask may help the client with shortness of breath, but it does not address the underlying cause of the respiratory depression, which is the overdose of morphine. The nurse should first remove the source of the excess morphine and then provide oxygen therapy as needed.

Choice B reason: This is the first action for the nurse to take. Removing the morphine patches is the most urgent and effective way to stop the further absorption of the drug and reduce the risk of life-threatening complications, such as respiratory arrest, coma, or death. The nurse should remove all the patches from the client's body and dispose of them safely. The nurse should also notify the healthcare provider and prepare to administer a narcotic reversal drug, such as naloxone, if indicated.

Choice C reason: This is not the first action for the nurse to take. Administering a narcotic reversal drug may be necessary to reverse the effects of the morphine overdose, but it is not the most immediate intervention. The nurse should first remove the morphine patches to prevent further exposure and then assess the client's level of consciousness, respiratory rate, and oxygen saturation. The nurse should follow the healthcare provider's orders and the facility's protocol for administering a narcotic reversal drug.

Choice D reason: This is not the first action for the nurse to take. Monitoring blood pressure may be important to assess the client's hemodynamic status, but it is not the most critical intervention. The nurse should first remove the morphine patches to prevent further deterioration and then monitor the client's vital signs, including blood pressure, pulse, and temperature. The nurse should also watch for signs of hypotension, shock, or cardiac arrest.
