What position should a patient with nausea and vomiting be placed in?

The left lateral position is ideal for a patient experiencing nausea and vomiting for several reasons. This position allows gravity to assist in keeping the contents of the stomach from coming back up the esophagus, which can help prevent aspiration. Aspiration occurs when vomit enters the lungs, potentially leading to serious complications such as aspiration pneumonia.

Moreover, being in the left lateral position can also promote better drainage from the stomach, aiding in comfort and minimizing the likelihood of choking. This is particularly important in an emergency medical situation, where protecting the patient's airway is crucial.

In contrast, while sitting upright can be helpful for some patients by reducing the risk of aspiration, it may not provide enough support for a patient who is unstable or faint. The supine position places the patient flat on their back, which can increase the risk of aspiration if they vomit. Finally, being comfortable on their back does not specifically address the risks associated with nausea and vomiting, particularly regarding airway protection and aspiration.
