A client with chemotherapy-induced nausea receives a prescription for metoclopramide. Which adverse effect is most important for the nurse to report?

Choice A Reason:Nausea is a common side effect of many medications, including metoclopramide. While it is important to monitor, it is not the most critical adverse effect to report. Metoclopramide is often prescribed to manage nausea, so experiencing this symptom may indicate the need for dosage adjustment or additional supportive care, but it is not an emergency.Choice B Reason:Diarrhea is another common side effect of metoclopramide. It can be uncomfortable and may require management, but it is not typically life-threatening. The nurse should monitor the client and provide supportive care, but this side effect does not necessitate immediate reporting unless it becomes severe or persistent.Choice C Reason:Unusual irritability can occur with metoclopramide use. While it is important to note changes in mood or behavior, this symptom is not as critical as some other potential adverse effects. The nurse should monitor the client and consider discussing this symptom with the healthcare provider, but it is not the most urgent concern.Choice D Reason:Involuntary movements, such as those seen in tardive dyskinesia, are a serious adverse effect of metoclopramide. Tardive dyskinesia is a potentially irreversible condition characterized by repetitive, involuntary movements, often of the face and tongue. This side effect is significant and requires immediate reporting to the healthcare provider, as it may necessitate discontinuation of the medication and further evaluation.
