1. Calculate the drip rate for 100 mls of IV Fluids to be given over a half hour via a giving set which delivers 10 drops/ml.

100 mls X 10 drops/ml----------------------------

30 min=

1000 drops------------------

30 min=  33 drops / min

time = half hour = 30 minutes

2. One litre of Normal Saline is charted over 9 hours. The drop factor is 15. Calculate the number of drops per minute.

1000 mls X 15 drops/ml----------------------------

540 min=

15000 drops------------------

540 min=  28 drops / min

[time = 9 hours = 9 x 60 = 540 minutes] [1 litre = 1000 mls]

3. One and a half litres of Normal Saline is required to be given over 4 hours. Using a giving set which delivers 10 drops/ml how many drops per minute will need to be given?

1500 mls X 10 drops/ml----------------------------

240 min=

15000 drops------------------

240 min=  63 drops / min

[time = 4 hours = 4 x 60 = 240 minutes] [1.5 litres = 1500 mls]

4. Three litres of Hartmans (Lactated Ringer's) is charted over 12 hours. The drop factor is 15. The IV has been running for 9 hours. 800 mls remain. How many drops per minute are needed so that the IV finishes in the required time?

800 mls X 15 drops/ml----------------------------

= 12000 drops------------------

=  67 drops / min

180 min 180 min[time remaining = 3 hours = 3 x 60 = 180 minutes] [volume remaining = 800 mls]

5. One litre of Dextrose 5% in water is charted over 3 hours. The drop factor is 10. The IV has been running for 1 hour and 15 minutes. 500 mls remain. How many drops per minute are needed so that the IV finishes in the required time?

500 mls X 10 drops/ml----------------------------

105 min=

5000 drops------------------

105 min=  48 drops / min

[time remaining = 1 hour 45 min = 105 minutes] [volume remaining = 500 ml

6. A client is ordered 0.5 milligrams of Digoxin. 250 microgram tablets are available. How many tablets will you give?

500 mcg (=0.5mg)---------------------------------

-250 mcg

= 2 tablets

7. A client is ordered 1 milligram of Diazepam. 2 milligram tablets are available. How many tablets will you give?

1 milligram---------------------------------

-2 milligram

= 0.5 tablets

8. A client is ordered 2.5 grams of Neomycin sulphate. 500 milligram tablets are available. How many tablets will you give?

2.5 grams---------------------------------

-500 mg = 0.5g

= 5 tablets

9. A client is ordered 50 milligrams of Aminophylline intravenously. 250 milligrams in 10 millilitres of liquid for IV Injection is available. How many millilitres will you administer?

13. Infuse 1000 units/hr of heparin from a solution of 1000ml of Normal Saline with 25000 units of heparin. Calculate the rate in ml/hr

Ratio and proportion:

25000units: 1000ml = 1000 units/ml

25000 = 1000 x 1000 = 1000,000 = 1000

25000 25000 25000 25

Ans = 40 ml/hr
