To determine the flow rate in drops per minute (gtts/min) for infusing 250 ml of a solution over 5 hours using microdrip tubing, you can follow these steps:

First, convert the total infusion time from hours to minutes. Since there are 60 minutes in an hour, 5 hours is equal to (5 \times 60 = 300) minutes.

Next, calculate the flow rate in ml per minute by dividing the total volume by the total time. This is done by taking the total volume of the solution (250 ml) and dividing it by the total infusion time (300 minutes):

[

\text{Flow rate (ml/min)} = \frac{250 \text{ ml}}{300 \text{ min}} \approx 0.833 \text{ ml/min}

]

For microdrip tubing, which delivers drops per ml, the common rate is typically 60 gtts/ml. To convert the flow rate from ml/min to gtts/min, multiply the flow rate in ml/min by the drop factor:

[

\text{Flow rate (gtts/min)} = 0.833 \text{ ml/min} \times 60 \text{ gtts/ml
