Tonicity________________
Run at _______mL/hr. Drop factor is 15 gtt/mL. IV to run at _____gtt/min
ANSWER.
* Calculation of tonicity and gtt/min.
Tonicity is the concentration of solutes in a solution.
Tonicity of 500 ml of 10% dextrose = 500 * 10/100 , (10% = 10/100)
= 5000/100
= 50 gm.
* Rate(gtt/min).
Formula
gtt/min = Volume(ml)/Time(min) * Droip factor(gtt/ml).
Here
Volume(ml) = 500 ml.
Time(min) = 300 min (5hr).
Drop factor = 15 gtt/min.
As per above formula
gtt/min = 500/300 * 15
= 1.66 * 15
= 24.9
= 25 gtt/min.
