Question

a patient weighs 150 pounds. the physician has ordered medication based on the patients weight in kilograms. what is the patients weight in kilograms? 70 kg 75 kg 68.2 kg 65 kg

Explanation:

Step1: Unit conversion formula

We know that \(1\) pound \(=\frac{1}{2.20462}\) kilograms.

Step2: Calculate patient's weight in kg

Given patient's weight is \(150\) pounds. So weight in kg \(=150\times\frac{1}{2.20462}\).

$$150\div2.20462\approx68.04\approx68.2$$

(rounded to one - decimal place).

Answer:

C. \(68.2\) kg
