NPO stands for:

• A. After
• B. By Mouth
• C. After Meals
• D. Nothing by Mouth

Answer: (D)

In medical terminology, NPO is an abbreviation that tells the patient not to take anything by mouth. Only the phrase “Nothing by Mouth” conveys that restriction, whereas the other phrases imply different instructions—one suggests being allowed to take things by mouth, another simply indicates timing without restriction. This designation is important before procedures like anesthesia or certain tests to reduce the risk of inhaling stomach contents. An NPO order is routinely used to keep the stomach empty, sometimes until a specific time, and clinicians may specify exceptions for essential medications or fluids as directed.
