NPO stands for which of the following?

NPO stands for which of the following?

• A. Nausea and vomiting
• B. Nothing by mouth
• C. Level of consciousness
• D. Shortness of breath

Answer: (B)

Nothing by mouth means the patient should not take any food or drink by mouth. This instruction is used to prevent aspiration during anesthesia or certain procedures, so staff will tell you to refrain from eating or drinking until you’re told it’s safe. In practice, NPO lasts from the time of the instruction until clearance, with possible small exceptions for necessary medications or IV fluids depending on the situation. The other terms describe symptoms or conditions (nausea, consciousness level, or shortness of breath) rather than a directive about oral intake.
