Typical NPO guidelines for solids before anesthesia recommend approximately:

• A. 1-2 hours
• B. 4-6 hours
• C. 6-8 hours
• D. 12-24 hours

Answer: (C)

Reducing aspiration risk by giving the stomach time to empty before anesthesia. Solid foods take longer to leave the stomach than liquids, so a longer fasting window is needed. Six to eight hours provides enough time for most solid meals to pass through the stomach, lowering the chance of regurgitation and airway injury when anesthesia is induced. A lighter meal might fit toward the shorter end, but heavier or fatty meals can require the full eight hours. Shorter intervals, like one to two hours, don’t reliably clear solid contents, and waiting 12–24 hours is unnecessarily long and impractical.
