From a 1 liter IV bag, if 125 mL is left, how many milliliters have been absorbed?

• A. 875 mL
• B. 125 mL
• C. 1000 mL
• D. 8750 mL

Answer: (A)

When you know the starting volume and how much is left, you find the absorbed amount by subtracting the remaining volume from the starting volume. A 1 liter bag equals 1000 milliliters. If 125 mL remains, the amount absorbed is 1000 mL − 125 mL = 875 mL. A quick cross-check in liters confirms this: 0.125 L left means 0.875 L absorbed, which is the same 875 mL. So 875 mL have been absorbed.
