Which is a recommended pre-operative restriction?

• A. Remove water 24 hours before
• B. Remove food 12 hours before procedure
• C. Begin sedation 6 hours before
• D. Skip pre-operative monitoring to save time

Answer: (B)

Pre-operative fasting to reduce the risk of aspiration during anesthesia. When anesthesia is given, airway reflexes are suppressed, so stomach contents can be regurgitated into the lungs if the stomach isn’t empty. Refraining from eating for a period before the procedure helps ensure the stomach is empty at induction, lowering the chance of aspiration. A twelve-hour restriction on eating is a conservative rule that increases safety by allowing more time for stomach emptying. The other options don’t fit safety practices. Removing water well before the procedure isn’t standard; many guidelines allow clear fluids up to a couple of hours beforehand, and prolonged water restriction can lead to dehydration. Beginning sedation long before the procedure would disrupt timing and could compromise safety. Skipping pre-operative monitoring would omit essential checks of the patient’s status and risk factors before anesthesia.
