What does NPO mean in the context of patient care?

In the context of patient care, NPO stands for "nothing per os," which means that the patient should not take anything by mouth. This directive is often given before surgical procedures, diagnostic tests, or certain medical treatments to reduce the risk of complications such as aspiration. By ensuring that the patient has an empty stomach, healthcare providers can minimize the chances of food or liquid interfering with the treatment or affecting the patient's safety.

Understanding the importance of NPO status is crucial for medical scribes, as it directly impacts patient management and preparation. For example, if a patient is scheduled for surgery, adhering to NPO guidelines ensures the surgical team can perform the procedure without the risks associated with anesthesia and the presence of food or liquid in the stomach. Therefore, recognizing that NPO indicates a restriction on oral intake is fundamental for proper patient care procedures.
