Final answer:
To calculate the day supply for a Proair 8.5gm inhaler with 2 puffs taken four times a day, we need to know the number of doses in the inhaler.
Step-by-step explanation:
To calculate the day supply for a Proair 8.5gm inhaler with 2 puffs taken four times a day, we need to know the number of doses in the inhaler. The given information states that the inhaler is a 200 MDI (metered-dose inhaler). Each MDI delivers a specified volume of medicine, which is not provided in the question. Without that information, it is not possible to accurately calculate the day supply. We would need to know the volume of medicine delivered by each puff or the total volume in the inhaler.
