Question: 1 / 400

What does the acronym "NPO" stand for in medical contexts?

Nothing by mouth

In medical contexts, the acronym "NPO" stands for "Nothing by mouth." This designation is typically used to instruct that a patient should not consume any food or fluids, including water, for a specific period of time. This is often necessary before surgical procedures or certain diagnostic tests, as it helps to prevent complications such as aspiration during anesthesia or ensures accurate test results.

Understanding this abbreviation is crucial for healthcare professionals as it impacts patient care planning and preparation for procedures. For example, when a patient is indicated as NPO, nurses and healthcare team members must ensure that they adhere to this guideline and manage any patient comfort or hydration needs appropriately prior to the procedure. It represents a fundamental aspect of patient safety and care in various medical settings.
