Calculation
An IV of 500 mL D5W is to infuse at 75 mL/hr. The IV was started at 10:00 PM. At what time would the IV infusion be completed? Enter answer in military time. Round to the nearest whole number of minutes and enter numeric value only (no commas or labels) Answer in military time. ________
Explanation & Rationale
Step 1 is to calculate the total infusion time in hours Total hours = Total volume ÷ mL/hr 500 ÷ 75 = 6.6666... hours Step 2 is to convert the decimal portion of the hours into minutes Minutes = 0.6666... × 60 minutes 0.6666... × 60 = 40 minutes Total time = 6 hours and 40 minutes Step 3 is to convert the start time to military time 10:00 PM = 2200 Step 4 is to add the infusion time to the start time 2200 + 0640 = Result 2200 + 0200 (to reach midnight) = 2400 (or 0000) Remaining time to add = 4 hours and 40 minutes 0000 + 0440 = 0440 Answer: 0440
