DRUG CALCULATIONS

When calculating how much of a drug is required, working with the formula helps the accuracy of the calculation.

Always remember this formula:

What you want X Quantity it comes in

What you have 1

to use a calculator!

1. A patient requires 4 mg of Morphine IVI. Morphine is available as

10mg/ml. How many mls will you draw up?

2. Gentamycin 360 mg is prescribed. Gentamycin is available as

80mg/2ml. How many mls will you draw up?

3. Haloperidol 3 mg IVI is charted. Haloperidol is available as 5mg/ml.

How many mls is required?

4. Frusemide 70mg IVI is charted. Stock dose is 20mg/ml. How many ml

would you give?

METRIC CONVERSIONS

Metric weights and measurements involve a step-by-step conversion from one unit to another. With weight we often convert to smaller (and more numerous units) thus:

Kg gm mg mcg

grams milligrams micrograms Each of these steps involves the heavier unit being multiplied by 1000 to bring up the number of the smaller units for the same weight. kg g 1kg x 1000 = 1000g g mg 1g x 1000 = 1000mg mg mcg 1mg x 1000 = 1000mcg the right

0.5g == ?? mg 0.5 x 1000 == 500mg

1 place = 5

2 places = 50

3 places = 500

If we are converting from a lighter unit to a heavier unit we move the decimal point three places to the left for each conversion. Another way of putting it is we divide by 1000. mcg mg 1000mcg

1000 = 1mg

mg gm 1000mg

1000 = 1gm

gm kg 1000gm

1000 = 1kg

500mg = ?? gm 500

1000 = 0.5mg

1 place = 50

2 places = 5

3 places = 0.5

Memory Tip:

Try these:

5. Atropine 0.6 mg = ?mcg

0.6 x 1000 = 600mcg

6. 0.01gm = ? mg

0.01 x 1000 = 10 mg

7. Gentamycin 360mg = ?gm

360

1000 = 0.36gm

8. Digoxin 125mcg = ? mg

125

1000 = 0.125mg

If we are moving across two conversions we repeat the process twice.

For example from grams to micrograms:

3gm converted to micrograms

Step one:

= 3 x 1000 = 3000mg

Step two:

3000mg x 1000 = 3,000,000mcg

9. Augmentin 1.2gm = ?mcg

1.2 x 1000 = 1200mg

1200 x 1000 = 1,200,000mcg

10. Digoxin 125mcg = ? gm

125

1000 = 0.125mg

0.125

1000 = 0.000125gm

Try these:

Convert

11. 1.2 mg to mcg

12. 1.3g to mg

13. 500mcg to mg

14. 0.04 mg to mcg

15. 20mcg to mg

16. 600mcg to g

MG/KG DOSE CONVERSION

Often we need to check the dose of a drug or solution that is based We multiply the prescribed mg dose by the kg weight of the patient

Prescribed dose - 25mg per kg

- 66kg

What is the dose required?

25mg x 66kg = 1650mg

= 1.65g

21. Prescribed dose 50 mg/kg
