What does NPO stand for in medical orders?

• A. Not prepared on-site
• B. Nothing by mouth
• C. Note preferences only
• D. Nothing pureed only

Answer: (B)

NPO means nothing by mouth. It’s an order that tells the patient not to take any food or fluids by mouth, to keep the stomach empty and reduce the risk of choking or aspiration during procedures or anesthesia. The term comes from the Latin nil per os, literally “nothing through the mouth.” In practice, it covers all oral intake unless a clinician specifies an exception, such as allowing a small amount of water for essential medications if approved. Other options don’t describe this fasting directive.
