At the beginning of a shift, a client's IV bag has 900 mL remaining. The IV is infusing at 75 mL/hour. In 8 hours, how many mL should remain in the IV bag?

Calculate the total volume to be infused over 8 hours: Total volume infused (mL) = Infusion rate (mL/hour) x Infusion time (hours) = 75 mL/hour x 8 hours = 600 mL Calculate the remaining volume in the IV bag after 8 hours: Remaining volume (mL) = Initial volume (mL) - Total volume infused (mL) = 900 mL - 600 mL = 300 mL
