A medication must be infused at 75 mL/hour. How many mL will be delivered in 8 hours?

• A. 575 mL
• B. 600 mL
• C. 675 mL
• D. 525 mL

Answer: (B)

Infusion volume comes from multiplying the rate by the time. If a medication is given at 75 mL per hour for 8 hours, multiply 75 by 8. 75 × 8 = 600. The hours cancel, leaving the units in milliliters, so the total delivered is 600 mL. The other numbers would come from an incorrect calculation or misreading of time, but the correct product is 600 mL.
