Additional IV Practice Problems

1)Order:  D5W 1250 ml IV every 12 hours.  Tubing calibrated at 10 gtt/ml.  Calculate the flow rate and drip rate.

 

 

2.The patient must receive a parenteral feeding of 240 ml in 90 minutes.  Tubing is calibrated at 20 gtt/ml.

Flow rate and drip rate?

 

 

3.The order is for 500 ml of D5W to infuse IV in 5 hours.

 

a.Calculate the drip rate if the drop factor is 15 gtt/ml.

 

b.When the nurse checks the infusion 2 hours after it started, 400 ml remains to be infused in the

remaining 3 hours.  Recalculate the drip rate.

 

 

4.An IV is flowing at 25 gtt/min, using 10 gtt/ml tubing.  What is the flow rate in ml/hr?

     

 

 

5.The prescriber orders D5 ½ NS to infuse at 21 gtt/min.  If the drop factor is 20 gtt/ml, what is the flow

rate?

 

 

6.D5W is infusing at 75 ml/hr.  Antibiotic A with 3 g in 250 ml is to infuse twice daily (infuse over 60

minutes), antibiotic B with 1 g in 100 ml is to infuse every 6 hours (infuse over 1 hour), and antibiotic C

750 mg in 50 ml is to infuse every 12 hours (infuse over 30 minutes).  What is the total 24-hour

parenteral intake?

 

 

7.An infusion of 500 ml NS has been ordered.  The drip rate is 27 gtt/min, and the drop factor is 15 gtt/ml.

How long will it take for this infusion to finish?

 

8.The patient is to receive 150 ml of an antibiotic in the 2-hour window prior to his surgery, which is

scheduled for 1430.  To be sure it’s infused on time, you hang the antibiotic at 75 ml/hr at 1200.  At 1230

the patient is disconnected from his IV for a pre-op Xray, and does not return until 1315.  At what rate

will you now have to set the pump to complete its infusion by 1430?

All you need to solve this problem is how much fluid is left, and how much time is left.

By 1230, 37.5 ml has infused, leaving 112.5 ml.  When patient returns, there is 1 hr 15 minutes left until

surgery, so:

 

 

9.The patient has 850 ml of D5NS to infuse at 80  ml/hr.  How long will it take?

 

10.The order reads 1000 ml D5W IV over 8 hours.  Drop factor is 10 gtt/ml.

a.Drip rate?

 

 

 

b.After 5 hours, 700 ml remains to be infused.  What flow rate should be set so the infusion will finish on time?

 

c.What is the new drip rate?

 

11.The patient is receiving NS at 125 ml/hr.  Also ordered:  antibiotic A with 1 g in 50 ml every 8 hours

(infuse over 30 minutes), antibiotic B with 1 g in 200 ml twice daily (infuse over 90 minutes).  24-hour

total?

 

 

12.Calculate the drip rate for 2000 ml at 125 ml/hr, tubing available 15 gtt/ml.

 

13.Order:  Infuse 15 ml of medication in 20 minutes using microdrip tubing (60 gtt/ml tubing).  At what

rate will you set the pump?

 

 

14.Order:  Infuse 1000 ml NS in 8 hours.  It has been running at 31 gtt/min.  In four hours, only 425 ml has infused.  Using 15 gtt/ml tubing, at what drip rate will you reset the IV, in order to complete the infusion in a total of 8 hours (with only 4 remaining)?How much is left? 

 

15.D5 ½ NS is running at 27 gtt/min, using 15 gtt/ml tubing.  How many ml/hr is the patient receiving?

 

16.The patient is to receive 300 ml NS in 4 hours.  Calculate the flow rate in microdrips/minute.  (This just indicates you will be using microdrip tubing which is 60 gtt/ml tubing.)

 

17.The order is for a 200 ml dose of Levaquin to be administered in the 2-hour window before the patient’s

scheduled surgery at 1300.  You hang the antibiotic at 1100, infusing at 100 ml/hr.  At 1145, the IV is

disconnected for a final pre-surgery MRI, and the patient does not return to the floor until 1230.  What

rate will you need to set on the pump to be sure all of the antibiotic is infused by 1300?

 

18.500 ml is to infuse at 20 gtt/min.  Using 10 gtt/ml tubing, how long will it take to run?

 

19.550 ml remain in the IV bag.  It is 0800.  If the IV is running at 53 gtt/min and the drop factor is 30

gtt/ml, at what time should the IV finish?

 

20.Order written (and hung) at noon:  Infuse 1000 ml D5W in 8 hours.  The IV was stopped for patient

testing at 1830 for 45 minutes, with 90 ml of D5W still in the bag.  What should the pump be set at to

finish the infusion on time?

 

 

21.350 ml of D5 ½ NS is running at 27 gtt/min using 15 gtt/ml tubing.  How long will it take to empty the

bag?

 

22.How long will it take for 500 ml to infuse, if it is ordered to run at 40 ml/hr?

 

23.The IV is infusing at 30 gtt/min, using 15 gtt/ml tubing.  What is the flow rate?

 

24.1000 ml of D5W is to infuse at 30 gtt/min for 10 hours.  After four hours, the patient has received 500

ml.  The drop factor available is 15 gtt/ml.

a.What was the original flow rate?

 

 

b.At what new flow rate should the infusion be set, in order to follow the original orders?

 

c.What will be the new drip rate?
