How much total volume does the vial contain?

• A. 5 mL
• B. 0.5 mL
• C. 2 mL
• D. 1 mL

Answer: (D)

Vial capacity is determined by the highest graduation or fill line on the vial. When the liquid level aligns with the 1 mL mark, that indicates the vial’s total volume—the maximum it can hold—is 1 mL. The other numbers would require the liquid to reach different marks that aren’t reached here, so they don’t match the observed fill. Remember, this is about how much the vial can contain overall, not necessarily the amount you withdraw for a dose.
