If an albuterol inhaler delivers 90 mcg per actuation, and each container delivers 200 actuations, how many mg are delivered in each dose of 2 actuations?

To find out how many milligrams are delivered in each dose of 2 actuations from an albuterol inhaler that delivers 90 mcg per actuation, first, calculate the total micrograms delivered in 2 actuations.

Each actuation provides 90 mcg, so for 2 actuations, the calculation is:

90 mcg/actuation × 2 actuations = 180 mcg

Next, it's essential to convert micrograms (mcg) into milligrams (mg). The conversion factor is:

1 mg = 1000 mcg

To convert 180 mcg to mg, use the following calculation:

180 mcg ÷ 1000 = 0.18 mg

Thus, each dose of 2 actuations delivers 0.18 mg of albuterol. The correct answer reflects this calculation, confirming that 0.18 mg is indeed the correct dosage delivered from 2 actuations.
