Question 36

The Albuterol HFA inhaler provides a 16-day supply when inhaled as directed.

Using the prescribed dosage of 2 puffs every 4 hours, the total number of inhalations in a day is calculated to be 12 puffs (2 puffs x 6 doses). Given that the inhaler contains 200 inhalations, dividing 200 by 12 results in approximately 16.67 days, which rounds to 16 days.

A) 10

Option A is incorrect. If the inhaler were to provide a 10-day supply, it would imply a usage of 20 inhalations per day. However, with the prescribed regimen of 2 puffs every 4 hours, the actual daily usage is only 12 inhalations, making 10 days unfeasible.

B) 16

Option B is correct. The calculation of 200 inhalations divided by the 12 inhalations used per day results in approximately 16.67 days. Thus, the inhaler can sustain the prescribed usage for about 16 days, confirming this option as accurate.

C) 30

Option C is incorrect. A 30-day supply would require a significantly lower daily use of inhalations, approximately 6.67 puffs per day. Given the prescribed frequency of 12 puffs daily, this option does not align with the actual usage.

D) 90

Option D is also incorrect. A 90-day supply would suggest a daily use of only about 2.22 inhalations, which is far lower than the prescribed 12 inhalations per day. Therefore, this option cannot be correct.

Conclusion

The correct answer is 16 days, based on the calculation of total inhalations per day compared to the total available in the inhaler. All other options fail to accurately reflect the prescribed usage, highlighting that only Option B aligns with the given dosage schedule.
