Question 40

A diabetic coma patient needs to be treated successfully with an insulin dose rate of 0.5 units/kg of body weight. She currently weighs 65 kilograms and the insulin you have available has a concentration of 60 units/milliliter. Calculate how much you need to inject to treat her. Your answer should be rounded to the nearest 1/100th.

Answer 40

–weight multiplied by units per kg (65x.5)
–take that number (32.5) divide by concentration (60 units/ milli)
-0.54
