Question

the dose of a drug is critical. too small a dose may not treat a patient effectively, while too much can cause serious side effects. a nurse must give a patient 40 mg of a drug for each kilogram of the patient’s mass. if a patient weighs 165 lb, how many milligrams of the drug should be given? use 1 kg = 2.2 lb and do not round any computations.

Explanation:

Step1: Convert lbs to kg

$\text{Patient's mass in kg} = \frac{165}{2.2}$

Step2: Calculate total drug dose

$\text{Total dose (mg)} = 40 \times \frac{165}{2.2}$

Answer:

3000 mg
