Question

 

1.) Calculate the flow rate in gtt/min. (Simplify your answer completely. Express your answer to the nearest whole number.)

The order is for 700 mL in 8 hr. The set is calibrated at 15 gtt/mL.

2.) Calculate the flow rate in gtt/min. (Simplify your answer completely.)

Administer 180 mL in 6 hr. A microdrip is used.

3.) Calculate the flow rate in gtt/min. (Simplify your answer completely. Express your answer to the nearest whole number.)

1,700 mL has been ordered to infuse in 16 hr. Set calibration is 20 gtt/mL.

4.) Calculate the flow rate in gtt/min. (Simplify your answer completely. Express your answer to the nearest whole number.)

The order is to infuse a liter in 10 hr. At the end of 8 hr, you notice that there are 400 mL left. What would the new flow rate need to be to finish on schedule if the set calibration is 10 gtt/mL?

5.) Calculate the flow rate in gtt/min. (Simplify your answer completely. Express your answer to the nearest whole number.)

An IV was started at 9 am with orders to infuse 500 mL in 8 hr. At noon, the IV infiltrated with 340 mL left in the bag. At 1 pm, the IV was restarted. The set calibration is 20 gtt/mL. Calculate the new flow rate to deliver the infusion on time.

Answer 1

1. Given the total volume of iv is 700 ml

Total time is 8hrs

Calibrate is 15 gtt/ml

Then number of drops per minute (flow rate) is

=total volume (ml) *drop factor (gtt/ml) /total time (min)

=700*15/8*60=2.18 drops per minute

Therefore the number of drops per minute of the given iv is 2 drops per minute(gtt/min) .

2.given total volume of iv is 180ml

Total time is 6hrs =6*60min =360min

Microdrip tubing delivers 60 gtts/mL and is used for small or very precise amounts of fluid, as with neonates or pediatric patients.

Flow rate =total volume (ml) *drop factor(gtt/ml) /total time (min)

=180*60/360

=30 drops per min (gtt/min)

Therefore the flow rate in drops per minute is 30 gtt /ml

3.given total volume of iv is 1700 ml

Total time is 16hrs =16*60 minutes =960 minutes

Drop factor is 20gtt/ml

Flow rate =1700*20/960=35.41 gtt/min

Therefore the flow rate is 35 gtt/min

4.given the volume after 8hrs is 400ml

Time left for that iv flow is =10-8=2hrs =2*60mins =120min

Given calibration is 10gtt/ml

Flow rate =400*10/120=33.33 gtt/min

There fore the flow rate is 33 gtt/min

5. Given total volume left at 1pm is 340 ml

Time left after 1pm is =8-4=4hrs =4*60min=240 min

New calibration is 20gtt/ml

Flow rate =340*20/24=28.33gtt/min

Therefore the new flow rate is 28 gtt/min
