What does q.s. indicate?

• A. Quantity sufficient
• B. Quantity standard
• C. Quick syrup
• D. Quasi solution

Answer: (A)

The idea being tested is that q.s. stands for a quantity sufficient. It’s a labeling shorthand used in compounding to tell you to add enough solvent or diluent to reach the final desired total. So, if a formulation says to add water q.s. to 100 mL, you keep adding water until the mixture reaches exactly 100 mL. It ensures the final product has the correct volume or weight without specifying a fixed amount in advance. The other options don’t reflect this common pharmacy shorthand.
