What is the meaning of NPO in medical terms?

NPO stands for "nil per os," which is a Latin term that translates to "nothing by mouth." This designation is typically used in medical settings to indicate that a patient should not consume any food or drink for a specified period. This is often necessary before surgical procedures, diagnostic tests, or certain treatments to minimize the risk of aspiration or other complications.

Understanding this term is essential for medical professionals, including scribes, as it helps ensure proper patient care and adherence to protocols surrounding preparation for medical interventions. The other choices either do not accurately convey the meaning of NPO or refer to concepts that are not relevant in the context of patient intake instructions.
