1000ml d5w iv to infuse @ 25gtt/min. the drop factor is 15gtt/ml.

flow rate:_______________ ml/h

total infusion time:____________ hours

25 gtts/minute

(drip rate)

x 1 ml/15 gtts

(drop factor of iv tubing)

x 60 minutes/1 hour

(conversion factor) =

100 ml/hour

(flow rate)

1000 ml at 100 ml/hour =

10 hours

for the iv to infuse

1l d5w w/ 10,000 units heparin to infuse @ 1,000 units/h. the drop factor is 20 gtt/ml.

flow rate:_______________ ml/min

1000 units

(dose desired)

/10,000 units

(dose on hand)

x 1000 ml

(amount)

/hour x 1 hour/60 minutes

(conversion factor) =

1.666 ml/minute

1000/ ( 25*60/15)

1000/100

10 hours

-------

1 liter = 10.000 units

she wants 1.000 per hour wich is 100 ml/h

now she is asking per minutes you divide it into 60 because there are 60 mins in 1 hour

and you get 1.66666~

which you round to then nearest hundreth and have 1.67 ml/min!!!

there you go:d
