At 1630 hours you started an IV with 500 cc of D5W running at 60 gtt/min using microdrip tubing (60 gtt/cc). You now receive a BAXTER IV Pump. A) How many cc/hr should you set the pump for to keep the IV going at the same rate?

B) What time will the infusion be completed?

A. 60 cc/hr

B. 00:50 hours

Explanation:

A) How many cc/hr should you set the pump for to keep the IV going at the same rate?

Since we have 60 gtt/cc microdrip tubing and the D5W is running at 60gtt/min.

The number of cc/min = 60 gtt/min ÷ 60 gtt/cc = 1 cc/min

So, the number of cc/hr = 1 cc/min × 60 min/1 hr = 60 cc/hr

B) What time will the infusion be completed?

Since we have 500 cc and an infusion rate of 60 cc/hr, the time taken for the infusion to complete, t = volume/infusion rate = 500 cc ÷ 60 cc/hr = 500/60 = 8¹/₃ hrs = 8 hrs 20 mins.

Since the infusion started at 16:30 hours, 8 hrs 20 mins later is 16:30 + 8:20 = 24:50 hours = 00:50 hours.

So, the infusion will be completed at 00:50 hours.
