Flow rate: ________ gtt/hour.

A. 556
B. 278
C. 139
D. 111.2

Answer :

Final answer:

The correct flow rate for the given infuse order and drop factor is c) 139 gtt/hour.

Explanation:

To calculate the flow rate in an IV infusion, the following formula is used: Flow rate (gtt/min) = Total volume (in ml) * drop factor (gtt/ml) / time (in min). However, in this question, we already have the flow rate provided which is 139 gtt/hour. This indicates option c) 139 is the correct flow rate for the given order. The infuse order and the drop factor has been factored into this calculation.
