Assistive Medication Administration Personnel (AMAP) Practice Exam

What is the unit of measure that equals milliliters in liquid medication?

1. Microgram

2. Milligram

3. Cubic centimeter

4. Gram

The correct answer is: Cubic centimeter

Cubic centimeters are equivalent to milliliters when it comes to measuring liquid medication. This relationship is fundamental in pharmacology and nursing, as it allows for precise dosing of medications, particularly in liquid form. Both milliliters and cubic centimeters express volume, and the two are interchangeable — 1 milliliter is equal to 1 cubic centimeter. This understanding is crucial for AMAP personnel when preparing, administering, or tracking medications, ensuring the correct dosage is given to individuals. The other options refer to units of weight or mass rather than volume. Micrograms and milligrams are measurements of mass, which are used for solid medications or to quantify very small amounts of active ingredients within formulations. Grams also reflect mass, but at a larger scale than micrograms or milligrams. Recognizing the difference between these units is essential for safe and effective medication administration.
