If a patient is experiencing nausea and vomiting, what should be done immediately concerning intake?

In situations where a patient is experiencing nausea and vomiting, keeping the patient NPO, or "nothing by mouth," is generally the most appropriate immediate action. This approach helps to prevent further irritation of the stomach and potential complications such as aspiration. When a patient is nauseous, the digestive system may not be able to handle food or liquids, which could exacerbate their symptoms.

While antiemetic medications are helpful for managing symptoms, they should not be the first intervention if the patient is currently vomiting or feeling nauseous. The goal is to stabilize the patient first by eliminating the risk of further intake. Allowing thin liquids or bland foods too soon can lead to increased discomfort or recurrent vomiting. Thus, the safest and most effective immediate action is to ensure the patient remains NPO until they can tolerate intake without nausea.
