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?

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?

• A. 2.5 mg
• B. 0.4 mg
• C. 100 mg
• D. 10 mg

Answer: (C)

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.

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.
