Drops/Minute?

Intravenous Flow Rates
FC = flow rate conversion number (flow converter)
Used for gravity systems
Measured in drops/minute (gtts/min)

FC = 60 (quotient of 60)
‐‐‐‐‐‐‐‐‐
DF (drop factor based on the solution set)

Therefore, 60/15 = 4 gtts/minute (flow rate conversion number)

Great breakdown! But that answer was not correct! This question really has me stomped! 

Need to know the amount of time the 1000 ml bag is to be run (8 hours?); can't go any farther with the information initially given.

That's the problem, the number of hours were not given. This is from HESI case study called Hepatitis.

IV Rates (Cont.)

To change from mL/hr to gtt/min
DIVIDE the given rate (ml/hr) by FC
“if you want DROPS, DIVIDE”

To change from gtt/min to mL/hr
MULTIPLY the given rate (gtt/min) by FC
“if you want MLs, MULTIPLY”

(from my first year nursing notes - pharmacology class)

Suppose we say the 1000mls are to run over 12 hours....

Divide 1000/12 (to give number of mls per hour) = 83.333ml/hr

Next, divide 83.33 by 60 (to give mls per minute) = 1.389 mls/minute

given the drop factor is 15 drops/ml/minute, multiply 15 (drops/minute) x 1.389 (number of mls/minute) = 20.835 (round up to nearest drop) to give 21 drops/minute...

Hope this helps!
 

Thank you! It helps a lot!!!! 

Please mark as solved.

the order is for normal saline at 100ml/hr, therefore: 100ml/hr x 1hr/60min(to convert hours to minutes) x 15drops/1ml(drop factor)= 25 drops/min...i set mine up as proportions. Hope this helps!!

Look at the asymptote on that motherfunction ^

Missing how long the 1000 Ml bag is to run for to plug into formula
VTI/ time in hours  X 15 ggts/ml/ 60 min =

The nurse sets up a 1000 mL bag of normal saline. The IV tubing has a drop factor of 15 drops/mL/minute. How many drops/minute will the normal saline be administered?

it is 25 gmasandra29 is correct.
