Answer:
<u>Flow rate = 16.67 gtts/min rounded to 17 gtts/min</u>
Explanation:
In order to calculate the flow rate, the following formula will be used.
Flow rate (gtts/min) = 
50 mL of fluid in which Ciprofloxacin is dissolved is taken as volume.
<u>KNOWN DATA:</u>
Volume = 50mL
Time = 45 minutes
Drop factor = 15 gtts/mL
Flow rate = unknown
<u>CALCULATION:</u>
Plugging the known values in the formula,
Flow rate (gtts/min) = 
Flow rate =
x 15
<u>Flow rate = 16.67 gtts/min.</u>
