Question

An IV bag of 500 mL solution is started at 1900. The flow rate is 38 gtts per minute, and the drop factor is 10 gtts per mL. At what time (24-hour clock) will this infusion finish?

Answer 1

Answer: your bag will finish at 2112.

Explanation: (38gtt/min) × (10gtt/ml).

Cross multiply. (38gtt×1ml) × (1min×10gtt)

This gives you 38/10...and the gtts cancel out so, it's 38ml/10min.

Simplify this to 3.8 ml/min.

Now, 3.8ml/x min = 500 ml.

Take 500/3.8. This gives you about 132 minutes if you round to the nearest minute. 60 min/he means 132 min = 2h12m. 2h12m from 1900 is 2112.
