The physician orders 1000 mL D5W to infuse over 10 hours. There is 375 mL left in the bag. How many hours and minutes will it be before the bag is empty?

Answer and Explanation

The Correct Answer is ["3.75"]

Step 1: Calculate the infusion rate per hour:
1000 mL ÷ 10 hours = 100 mL/hour

Step 2: Calculate time to infuse remaining 375 mL:
375 mL ÷ 100 mL/hour = 3.75 hours

Step 3: Convert 0.75 hour to minutes:
0.75 × 60 = 45 minutes

Final answer: 3 hours and 45 minutes

Rationale:
The infusion rate is constant. Time remaining = remaining volume ÷ rate. Convert decimal hours to minutes for precise documentation.
