What does NPO stand for in preoperative instructions?

• A. Nothing By Mouth
• B. Not Performed Operation
• C. New Patient Onset
• D. Not Planned Operation

Answer: (A)

NPO means nothing by mouth. This instruction is given before a procedure to keep the stomach empty so anesthesia can be given safely and the risk of aspiration of stomach contents into the lungs is reduced. In practice, patients are told not to eat or drink anything until the healthcare provider says it’s okay. The other options don’t fit this context: they don’t relate to preoperative fasting or patient instructions for safety around anesthesia. Sometimes, healthcare teams specify different allowances (for example, small sips of water for certain medications or clear liquids up to a few hours before surgery), but the core idea remains to avoid anything by mouth until cleared by the clinician.
