question 2 (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 mcg are needed to fill this rx per day?
Answer
Explanation:
Step1: Calculate minimum - dose per day
The minimum number of puffs per administration is 1, the minimum time - interval between administrations is 6 hours, and the minimum dose per puff is 90 mcg. In a 24 - hour day, the number of administrations $n_1=\frac{24}{6}=4$. So the minimum dose per day $d_1 = 1\times90\times4=360$ mcg.
Step2: Calculate maximum - dose per day
The maximum number of puffs per administration is 2, the maximum time - interval between administrations is 4 hours, and the maximum dose per puff is 180 mcg. In a 24 - hour day, the number of administrations $n_2=\frac{24}{4}=6$. So the maximum dose per day $d_2=2\times180\times6 = 2160$ mcg.
Answer:
The amount of mcg needed to fill the RX per day ranges from 360 mcg to 2160 mcg.
