What does "NPO" stand for in medication administration contexts?

"NPO" stands for "Nothing by mouth." This abbreviation is commonly used in medical contexts to indicate that a patient should not consume any food or liquids orally. It may be ordered before surgical procedures, certain medical tests, or in situations where the patient may be at risk for aspiration. Understanding this term is crucial for medication aides, as it directly impacts how and when medications should be administered, especially if they are required to be taken with food or water.

The other options do not relate to standard medical terminology used in medication administration. Being aware of such terminology ensures that medication aides can follow protocols for patient safety and treatment effectively.
