Question

question 3 (mandatory) (2 points)
a physician writes a prescription for proair hfa (albuterol sulfate) for chronic obstructive pulmonary disease (copd). the instructions state: inhale 1 to 2 mdi puffs (90 - 180mcg) q 4 - 6 hours.
how many puffs will the patient take daily?

Explanation:

Step1: Calculate minimum puffs per day

The minimum time - interval between doses is 4 hours. In a 24 - hour day, the number of 4 - hour intervals is $\frac{24}{4}=6$. The minimum number of puffs per dose is 1. So the minimum number of puffs per day is $1\times6 = 6$.

Step2: Calculate maximum puffs per day

The maximum time - interval between doses is 6 hours. In a 24 - hour day, the number of 6 - hour intervals is $\frac{24}{6}=4$. The maximum number of puffs per dose is 2. So the maximum number of puffs per day is $2\times4=8$.

Answer:

The patient will take 6 to 8 puffs daily.
