Question

The dose of a drug is critical. Too small a dose may be treat a patient effectively, A nurse must give a patient 40mg of a drug for each kilogram of the patient’s mass. If the patient weighs 165lbs how many milligrams of the drug should be given?

Answer 1

Step-by-step explanation

We need to multiply the number of needed milligrams by the weight of the patient, but first turning the weight in lbs into kilograms,

`?Kilograms=165lbs*(0.453)/(1lb)=74.745Kg`

Now, multiplying the obtained weight by the number of miligrams, give us the dose:

`Dose=40(mg)/(Kg)*74.745Kg=2989.8mg`

In conclusion, the nurse should give 2989 mg of the drug.
