NPO stands for?

Explanation:
NPO instructs that nothing should be taken by mouth. The shorthand comes from the Latin nil per os, literally meaning “nothing through the mouth.” In everyday clinical use, that instruction is commonly written or spoken as “Nothing by mouth,” which is why that phrasing is used as the correct choice in many exams. The Latin form represents the formal origin, while the English translation conveys the same restriction. The essential idea is a prohibition on oral intake to protect the airway or ensure safety before procedures or tests. The other phrasings either describe a similar idea with different wording or, in one case, describe something unrelated.
