Assistive Medication Administration Personnel (AMAP) Practice Exam

When administering medication, what does it mean if a medication is prescribed as "n.p.o."?

1. It should be taken with water

2. It should not be taken orally

3. There are no restrictions on its use

4. It is only for emergency use

The correct answer is: It should not be taken orally

When a medication is prescribed as "n.p.o.," which stands for the Latin phrase "nuli per os," it indicates that the patient should not take anything orally, including medication. This is a critical instruction that may be given for several reasons, such as when a patient is scheduled for surgery, to prepare for a diagnostic test, or due to a medical condition that affects their ability to safely swallow or absorb medication. Recognizing this abbreviation is essential for ensuring patient safety and proper medication administration practices. The other choices do not accurately reflect the meaning of "n.p.o." For example, indicating that the medication should be taken with water contradicts the "not taken orally" directive. Stating that there are no restrictions on its use directly opposes the purpose of the "n.p.o." order. Lastly, suggesting that it is only for emergency use does not encompass the broader implications of the "n.p.o." status, which applies under various circumstances, rather than just emergencies.
