Question 48

Albuterol 200 MDI, 2 puffs q6h prn lasts minimum 25 days.

Albuterol 200 MDI, when administered at a dosage of 2 puffs every 6 hours as needed, can be expected to last a minimum of 25 days based on the total number of puffs contained in the inhaler.

A) 10 days

This option is incorrect because 10 days is significantly less than the expected duration for the albuterol inhaler when used as prescribed. If the inhaler contains 200 puffs, using it for only 10 days would require a far greater frequency of use than the prescribed dosing.

B) 14 days

Option B is also incorrect as it underestimates the duration of the inhaler based on the prescribed usage. At the rate of 2 puffs every 6 hours, this would not be sustainable for just 14 days with the total puffs available.

C) 25 days

This is the correct answer. The inhaler provides 200 puffs, and at a dosage of 2 puffs every 6 hours, the total consumption per day would be 8 puffs. This means the inhaler would last approximately 25 days (200 puffs ÷ 8 puffs per day = 25 days).

D) 30 days

Option D is incorrect because it implies a longer duration than what is reasonable based on the prescribed dosage. At the rate of 2 puffs every 6 hours, the inhaler would not sustain usage for a full 30 days, which exceeds the calculated duration.

Conclusion

The correct answer is 25 days, as determined by the total number of puffs available in the inhaler and the prescribed frequency of use. All other options either underestimate or overestimate the duration based on this dosing schedule, highlighting the importance of accurate calculations in medication management.
