An aerosolized bronchodilator is being administered to a patient. The dose is 5.0 mL and the drug strength is 2.0%. How many milligrams of the drug will be administered?

To determine the amount of the drug being administered in milligrams, it's important to first understand the concentration of the drug solution in terms of the percentage specified.

A 2.0% solution means there are 2 grams of drug in every 100 mL of the solution. In this case, since we have a lower volume of 5.0 mL, we need to calculate how much drug is in that volume.

To find out how many grams are in 5.0 mL:

1. Calculate the amount of drug in 5.0 mL from the solution: [ \text{Amount of drug} = \text{Volume (mL)} \times \left( \frac{\text{Concentration (g/mL)}}{100 mL} \right) ] The concentration in grams per mL can be derived from the percentage: [ 2.0% = 2.0 g/100 mL = 0.02 g/mL ] Then calculate: [ \text{Amount of drug} = 5.0 mL \times 0.02 g/mL = 0.
