What does the abbreviation 'NPO' mean and when is it used in scheduling?

• A. Nothing by mouth; used to indicate fasting status for procedures or before anesthesia.
• B. Not patient only; used to authorize home visits.
• C. New patient orientation; used for scheduling.
• D. Non-payment order; used to delay appointments.

Answer: (A)

NPO means nothing by mouth. In scheduling, it signals that the patient must fast for a set period before a procedure or anesthesia to keep the stomach empty and reduce the risk of aspiration during anesthesia. Typical instructions specify no food or drink for a specified duration (often six to eight hours before the procedure, sometimes after midnight). Some policies allow small sips of water or certain medications with a small amount of water, but overall the rule is to avoid oral intake. The other options aren’t standard medical terms used in scheduling for procedures or anesthesia.
