Answer:
4.167 hours
Explanation:
The drop factor is the amount of fluid falling for one millimeter of fluid in gttt/ml.
The flow rate is the volume administered for a specific period of time in ml/hr = volume / time
The unit of drip rate is gtt/min
The formula that shows the relationship is:
Drip rate = flow rate × drop factor
Given that:
Drip rate = 60 gtt / min, Flow rate = volume / time = 500 ml / t, drop factor = 30 gtt/ml
Drip rate = flow rate × drop factor
60 = 500 / t × 30
500 / t = 60/30
500 / t = 2
2t = 500
t = 500/2
t = 250 mins
1 hr = 60 min
t = 250 / 60 hours = 4.167 hours
