*An IV of D5W 500 mL was ordered to infuse over 10 hr at a rate of 13 gtt/min (13 macrogtt/min). Drop factor: 15 gtt/mL After 3 hr, you notice that 300 mL of IV solution is left. Recalculate the rate in gtt/min for the remaining solution. _________________gtt/min

* An IV of 1,000 mL D5 1/2 NS has been ordered to infuse at 125 mL/hr. Drop factor: 15 gtt/mL The IV was hung at 7 AM. At 11 AM, you check the IV, and there is 400 mL left. Recalculate the rate in gtt/min for the remaining solution.

* An IV of 500 mL of 0.9% NS is to infuse in 6 hr at a rate of 14 gtt/min (14 macrogtt/min). Drop factor: 10 gtt/mL The IV was started at 7 AM. You check the IV at 8 AM, and 250 mL has infused. Recalculate the rate in gtt/min for the remaining solution. _______________gtt

*Order: Infuse 1,000 units/hr of heparin from a solution of 1,000 mL 0.45% NS with 25,000 units of heparin. Calculate the rate in mL/hr. _________________

Expert Solution

1. gtt/minute = total volume in ml/ time in min x drop factor in gtt/ml

Here, the remaining solution is 300 ml total volume to be infused.

time in minutes is the remaining 7 hr left.

the drop factor is 15 gtt /ml

, therefore, as per the equation = 300 x 15/7x60=4500/420= 11 gtt/minute.

2.As per the same equation gtt/min = 400 x15/4x60 = 6000/240=25 gtt/minute.

3.The remaining fluid is 250 ml.

remaining hours is 5 hours

drop factor 10

As per the above equation = 250 x 10/5x60=2500/300 = 8.33 gtt/ min or 8 gtt/minute

4.Total unit of heparin/total amount of infusion(mls) =units/hour divided by mls /hour

order is 1000 units of heparin

standard solution available is 1000ml with 25000 units of heparin

as per the equation = 25000/1000 =1000/x = 25/1=1000/x= 25x=1000 =x= 1000/25 = 40ml/hr.
