Which assessment is essential after inserting an NG tube?

The correct assessment after inserting a nasogastric (NG) tube is to check for respiratory distress. This is essential because there is a risk of inadvertently placing the tube in the trachea instead of the esophagus, which can lead to the tube entering the airway. If this happens, it can cause respiratory complications, such as aspiration, which can result in severe respiratory distress. Monitoring for signs of respiratory distress ensures that any potential complications are identified and addressed promptly.

While monitoring blood pressure, assessing for joint pain, and evaluating the mental state are important aspects of patient care, they do not specifically relate to the immediate risks associated with NG tube placement. Checking for respiratory distress directly addresses potential complications that can arise from incorrect tube placement and is therefore the most critical assessment to perform right after the procedure.
