What does the abbreviation NPO mean?

The abbreviation NPO stands for "nothing by mouth." This term is commonly used in medical settings to indicate that a patient should not consume any food or fluids, including water, for a specified period. This can be necessary for various reasons, such as before surgery, to prevent aspiration, or during certain medical procedures that require an empty stomach.

Understanding this abbreviation is crucial for pharmacy technicians, as it impacts medication administration, nutrition, and patient care protocols. It ensures that the healthcare team is aligned in maintaining the patient's safety and adhering to necessary medical guidelines during treatment. Other options present misunderstandings of what NPO signifies, as they do not accurately represent the concept of restricting oral intake.
