Intravenous Calculations

1. Directions: Determine the following in drops per minute using the drop factor provided.

Lactated Ringer solution is infusing at 45 microgtt/min. The drop factor is 60 gtt/mL. How much fluid volume will the client receive in 5 hr?

2. Directions: Determine the following in drops per minute using the drop factor provided.

D5 NS is infusing at 28 macrogtt/min. The drop factor is 10 gtt/mL. How much fluid volume will the client receive in 8 hr?

Answer 1

Answer 1:

Directions,   Microgtt/min = 45 drops

Drop factor = 60 gtt/ml

Total time = 5 hours

First of all we have to calculate how much ml fluid we are infusing per minute,

Formula, 1 minute = Microgtt/min devided by drop factor

1 minute = 45/60 ml.

1 minute = 0.75 ml.

Now we have to calculate fluid infused in 5 hours with the help of 0.75 ml/minute,

Formula, Total fluid infused = Time in minute multiply by infused volume per minute in ml

Total fluid infused = (5×60)×0.75 ml

Total fluid infused = 225 ml.

Answer 2:

Directions, Microgtt/min = 28 drops

Drop factor = 10 gtt/ml

Total time : 8 hours

First of all we have to calculate how much ml fluid we are infusing per minute,

Formula, 1 minute= Microgtt/min devided by drop factor

1 minute = 28/10 ml

1 minute = 2.8 ml

Now we have to calculate fluid infused in 8 hours with the help of 2.8 ml/minute

Formula, Total fluid infused = Time in minute multiply by infused volume per minute in ml

Total fluid infused = (8×60)×2.8 ml

Total fluid infused = 1344 ml.
