1 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 It s OK 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? 1

2 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 When we multiply by 1000 we move the decimal point three places to 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 mcg mg 1000mcg 1000 = 1mg mg gm 1000mg 1000 = 1gm gm kg 1000gm 1000 = 1kg 500mg =?? gm = 0.5mg 1 place = 50 2 places = 5 3 places = 0.5 2

3 Try these: 5. Atropine 0.6 mg =?mcg 0.6 x 1000 = 600mcg gm =? mg 0.01 x 1000 = 10 mg 7. Gentamycin 360mg =?gm = 0.36gm 8. Digoxin 125mcg =? mg = 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 = 0.125mg = gm Memory Tip: Heavy to light three places to the right 3

4 Try these: Convert mg to mcg g to mg mcg to mg mg to mcg mcg to mg mcg to g 17. 2g to mcg When we are converting volumes the process is the same. Litres ml 1 Litre 1000ml 0.25L 250ml 375ml 0.375L Try these: Convert ml to L ml to L L to ml 4

5 MG/KG DOSE CONVERSION Often we need to check the dose of a drug or solution that is based on the patient s weight. We multiply the prescribed mg dose by the kg weight of the patient Prescribed dose - 25mg per kg Patient s weight - 66kg What is the dose required? 25mg x 66kg = 1650mg = 1.65g 21. Prescribed dose 50 mg/kg Patient s weight 79 kg What is the dose required? 22. The patient is charted 15mg/kg/day. The patient weighs 75kg. a) How much is the total dose per 24 hours? b) How much will the patient receive every 8 hours? ROUNDING OFF the decimal point Rounding up if greater than 5, round up eg = 167 Rounding down if less than 5, round down eg = 33 5

6 INFUSION FLOW RATES To obtain the hourly rate, divide the volume of fluid to be infused by the number of hours fluid to be infused over. Eg: a 1000ml infused over 12 hours = 83.3ml/hr rounded down to 83ml/hr 23. A 1L bag is to be infused over 6 hours. Calculate how many mls per hour the patient will receive. 24. How many ml/hr would a patient receive if they were to have 500ml of fluid infused over 6 hours? Fluids are infused using a giving set, requiring a drop per minute rate. The giving sets are: Standard Metriset = delivers 20 drops per ml. Micro giving set (Buretrol) = delivers 60 drops per ml. Always ensure you use the appropriate calibration in your calculations. 6

7 DROP PER MINUTE Infusion Calculation Total fluid in mls x giving set calibration Total hours x 60 mins 1 A patient is prescribed Sodium Chloride 1000ml to be infused over an 8-hour period. A standard giving set is being used. Calculate the drops per minute X 20 =?drops per minute 8 x Your patient is prescribed a 1000ml infusion of Sodium Chloride 0.9% with 40 mmols of Potassium to be given over 6 hours. Using a buretrol giving set, calculate the drops per minutes he will receive. 7

8 DRUG CALCULATIONS ANSWERS 1. A patient requires 4 mg of Morphine IVI. Morphine is available as 10mg/ml. How many mls will you draw up? 0.4 mls 2. Gentamicin 360 mg is prescribed. Gentamicin is available as 80mg/2ml. How many mls will you draw up? 9 mls 3. Haloperidol 3 mg IVI is charted. Haloperidol is available as 5mg/ml. How many mls is required? 0.6 mls 4. Frusemide 70mg IVI is charted. Stock dose is 20mg/ml. How many ml would you give? 3.5 mls METRIC CONVERSIONS 5. Atropine 0.6 mg =?mcg 0.6 x 1000 = 600mcg gm =? mg 0.01 x 1000 = 10 mg 7. Gentamicin 360mg =?gm = 0.36gm 8. Digoxin 125mcg =? mg = 0.125mg 8

9 9. Augmentin 1.2gm =?mcg 1.2 x 1000 = 1200mg 1200 x 1000 = 1,200,000mcg 10. Digoxin 125mcg =? gm = 0.125mg = gm mg to mcg 1200 mcg g to mg 1300 mg mcg to mg 0.5 mg mg to mcg 40 mcg mcg to mg 0.02 mg mcg to g gm 17. 2g to mcg 2,000,000 mcg ml to L 0.45 L ml to L L L to ml 4,300 mls MG/KG DOSE CONVERSION 21. Prescribed dose 50 mg/kg Patient s weight 79 kg What is the dose required? 3950 mg 22. The patient is charted 15mg/kg/day. The patient weighs 75kg. a) How much is the total dose per 24 hours? 9

10 1125 mgs b) How much will the patient receive every 8 hours? 375 mgs Rounding off the decimal point Infusion Flow Rates 23. A 1L bag is to be infused over 6 hours. Calculate how many mls per hour the patient will receive mls 167 mls rounded 24. How many ml/hr would a patient receive if they were to have 500ml of fluid infused over 6 hours? 83.3 mls 83 mls rounded 25. Your patient is prescribed a 1000ml infusion of Sodium Chloride 0.9% with 40 mmols of Potassium to be given over 6 hours. Using a buretrol giving set, calculate the drops per minutes he will receive x 60 = drops per minutes rounded Remember all these calculations are based on clinical practice.
