What does "NPO" stand for in clinical terms when referring to feeding?

The term "NPO" is derived from the Latin phrase "Non Per Os," which translates to "nothing by mouth." In clinical practice, it indicates that a patient should not consume any food or drink orally. This directive is commonly implemented before surgeries, certain medical procedures, or in the case of specific medical conditions where oral intake could pose a risk or hinder treatment. It is crucial for healthcare providers to adhere to NPO guidelines to ensure patient safety and optimal outcomes during care. Understanding the significance of NPO is essential for nurses and healthcare professionals as it impacts preoperative protocols and patient management.
