Which abbreviation means as much as sufficient for total volume?

Explanation:
The key idea is a compounding instruction that tells you to fill up to a specified total volume. That instruction is quantum sufficit, abbreviated q.s., from Latin meaning “the amount sufficient.” When you see q.s. to a certain volume, it means add diluent or solvent until the final volume reaches that target. It’s about achieving the exact total volume needed, not about a fixed amount of active ingredient or a fixed dose. Understanding the other terms helps anchor the meaning: PRN means “as needed” for dosing, not about reaching a final volume; IU stands for “international units,” a potency-based dose; cc stands for cubic centimeters, a unit of volume, but it does not imply how to reach a final volume.
