1. Dosage Calculations Welcome to seminar 6

2. Celsius = (F – 32) / 1.8 Fahrenheit = 1.8 x celsius + 32

3. Eg 1. 212 f 212-32/1.8 = 100c 212-32= 180 180/1.8=100 c Eg 2. 42.3 c 1.8 x 42.3 + 32 = 108.1 f

6. Eg 1. Ordered morphine sulfate gr ¼ im Available morphine sulfate gr ½ ml How much would you give? ¼ x 60 = 15 mg ½ x 60 = 30 mg 15/30 = 0.5 ml

7. Eg 2. ordered: Furosemide 10 mg im Available: Lasix 40 mg/5ml How much will you give? 10/40 = 0.25 0.25 x 5 = 1.25 ml
