A nurse is assessing a client's ability to swallow. Which of the following, when selected by the nurse, indicates an understanding of the cranial nerve that tests the ability to swallow?

Choice A rationale: Nausea is the symptom the medication is intended to treat, and it is expected that the client may have some level of nausea while undergoing chemotherapy. It is not the most important adverse effect to report in this scenario.

Choice B rationale: Diarrhea is not a common or significant adverse effect of metoclopramide. While it is essential to monitor for any gastrointestinal side effects, it is not the most important adverse effect to report in this case.

Choice C rationale: Metoclopramide is a medication commonly used to treat nausea and vomiting, particularly related to chemotherapy. One of the significant adverse effects of metoclopramide is the potential to cause extrapyramidal symptoms, including involuntary movements such as dystonia, dyskinesia, and Parkinsonism. These extrapyramidal symptoms can be serious and may require immediate intervention or discontinuation of the medication.

Therefore, it is essential for the nurse to closely monitor the client for any signs of involuntary movements and report them promptly to the healthcare provider for appropriate management.

Choice D rationale: Unusual irritability is not a typical adverse effect associated with metoclopramide. While mood changes can occur with any medication, involuntary movements are a more concerning side effect that requires immediate attention and reporting.

Choice A rationale: Hematemesis refers to the vomiting of blood and is a severe and potentially life-threatening adverse effect of ibuprofen. Ibuprofen belongs to the class of nonsteroidal anti-inflammatory drugs (NSAIDs), which can cause gastrointestinal bleeding and ulcerations.

Hematemesis indicates significant gastrointestinal irritation or bleeding, and it requires immediate attention from the healthcare provider to assess and manage the client's condition.

Choice B rationale: Nausea is a common side effect of ibuprofen and other NSAIDs. While it is important to monitor and address any adverse effects experienced by the client, nausea alone is not as urgent or critical as hematemesis, which can indicate a more severe complication.

Choice C rationale: Insomnia is not directly related to the use of ibuprofen. While sleep disturbances can occur as a side effect of some medications, it is not the most important finding to report to the healthcare provider in this context.

Choice D rationale: Dizziness can be a side effect of ibuprofen, but it is not the most concerning finding in this situation. Hematemesis, which indicates potential gastrointestinal bleeding, is a more critical symptom that requires immediate attention and reporting to the healthcare provider.
