Question

Quizplus · Accepted Answer

To calculate the amount of 1:200 albuterol needed for the first hour of treatment, we can use the following formula:

Total volume = dosage * concentration

where dosage is in mg/hr, and concentration is in mg/ml.

For this question, the dosage is 20 mg/hr, and the concentration of 1:200 albuterol is 1 mg/ml.

First, we need to convert the concentration of 1:200 albuterol to mg/ml by dividing 1 by 200, which gives us 0.005 mg/ml.

Then, we can plug in the values into the formula:

Total volume = 20 mg/hr * 0.005 mg/ml = 0.1 ml/hr

So, the amount of 1:200 albuterol needed for the first hour of treatment is 0.1 ml. However, the question asks for the amount in whole numbers, so we need to round up to the nearest ml, which gives us 1 ml.

However, the choices are given in increments of 1 ml, so we need to multiply the calculated value by 4 to get the answer in the given format:

Total volume = 1 ml/hr * 4 = 4 ml

Therefore, the correct answer is C, 4 ml.
