What does "NPO" indicate for a resident's dietary restrictions?

"NPO," which stands for "nil per os" in Latin, directly translates to "nothing by mouth." This term is used in medical settings to indicate that a resident should not consume any food or drink for a specified period. This restriction might be necessary for various reasons, such as preparing for a surgical procedure, managing certain medical conditions, or preventing complications during treatment.

The other options provide dietary allowances, which contradict the meaning of NPO. The indication of being allowed to eat soft foods, drinking clear liquids, or needing to eat high-calorie foods does not apply when the directive is NPO, as it specifies a complete restriction from oral intake. Understanding this term is crucial for ensuring the safety and well-being of patients, especially in situations where food or liquid intake could pose risks to their health or interfere with medical interventions.
