Which of the following describes "NPO"?

The term "NPO" stands for "Nil Per Os," which is a Latin phrase meaning "nothing by mouth." In a medical context, this directive is used to indicate that a patient should not consume any food or drink, including water, prior to surgery, certain medical tests, or specific treatments. The purpose of this restriction is to reduce the risk of aspiration or complications during procedures that require general anesthesia or sedation, as well as to ensure accurate results in diagnostic tests.

Understanding the significance of NPO in clinical settings is vital for medication aides as it affects how and when medications may be administered, as well as dietary considerations for patients. Recognizing when a patient is NPO is crucial for providing safe and effective care.
