What does "NPO" stand for in a medical context?

In a medical context, "NPO" stands for "nothing by mouth." This term is commonly used to indicate that a patient should not consume any food or liquids. It is often instructed before surgeries, certain medical tests, or procedures to ensure that the stomach is empty, reducing the risk of complications such as aspiration or nausea during anesthesia.

The phrase is critical in healthcare settings, as it helps ensure patient safety and optimal outcomes during medical interventions. Proper adherence to NPO status is essential for both the patients being treated and healthcare professionals involved in their care. Understanding this term is essential for medical assistants and others in the healthcare field to communicate effectively and manage patient preparations properly.
