Question

Infuse 125 mL/hr of D5LR. The administration is 20 gtts/mL. Calculate the gtts/min. ___________

9. Infuse MgSO4 four grams IV over a 20 minute period. The medication is dissolved in 100 mL of NS. The administration set delivers 10 gtts/mL. Calculate gtts/min ___________. Calculate mL/hr__________

10. Administer 100 mL of Ampicillin in 30 minutes. The administration set delivers 10 gtts/mL. Calculate gtts/min.__________

Answer 1

Infusion rate of D5LR is 125ml/hr

Which means 125 ml in 60 min

Drop factor is 20gtts/ml

which means 20 drops form 1 mL

For 125 ml, it is = Volume * drop factor

which is 125 * 20 = 2500 gtts / hr

for 1 minute it is = 2500/60 gtts/min

which is 41.7 approximately. It can be rounded off to 42

So, drop factor is is 42 gtts/min approximately

9. Required dose of MgSO4 is 4 grams IV over 20 minutes

It is dissolved in 100 ml NS.

so, 100ml NS having 4 grams MgSO4 is infused over 20 minutes

100 ml in 20 minutes.

which means 5 ml in one minute and 300 ml in one hour

Drop factor is 10 gtts/ml

For 1 minute it is = Volume infused in 1 minute * drop factor

which is 5 * 10 = 50 gtts/min

For 1 hour it is = Volume infused in 1 hour * drop factor

which is 300 * 10 = 3000 gtts/hr.

10. Infusion rate of ampicillin is 100 ml in 30 minutes

drop factor is 10 gtts/ml

for 100 ml ampicillin it is = 100 * 10

which is 1000 gtts given in 30 minutes

for 1 minute it is = 1000/30 gtts/min

which is 33 gtts/min approximately
