Convert an infusion rate of 1.39ml/min to drops per minute using 60 gtts/ml tubing.

To find the infusion rate in drops per minute, you can use the formula that relates milliliters to drops by incorporating the drop factor of the infusion set. In this case, the tubing delivers 60 drops per milliliter (60 gtts/ml).

First, you have the infusion rate of 1.39 ml/min. To convert this rate into drops per minute, you multiply the infusion rate by the drop factor:

1.39 ml/min * 60 gtts/ml = 83.4 gtts/min.

This calculation shows that for every milliliter infused, 60 drops are delivered. Multiplying the volume infused per minute by the drops per milliliter provides the total rate in drops.

Thus, the conversion of 1.39 ml/min to drops per minute results in 83.4 drops, which corresponds to the correct answer. This highlights the importance of understanding the relationship between milliliters and drops, especially when dealing with intravenous therapy in a pharmacy or clinical setting.
