Answer
The dose of this medication for a 180-lb patient is equal to 409 mg.
Work Step by Step
1. Identify the equalities and conversion factors that we will use to solve this problem:
$$5.00 \space mg=1 \space kg \space of \space body \space weight$$ $$2.20 \space lb = 1 \space kg*$$
* Check Table 2.7 (Page 38)
2. Solve the problem using multiple conversion factors:
$$180 \space lb \space of \space body \space weight \times \frac{1 \space kg}{2.20 \space lb} \times \frac{5.00 \space mg}{1 \space kg \space of \space body \space weight} =$$ $$409 \space mg$$
