(Enter numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["17"]

To calculate the infusion rate, we need to use the formula:

Infusion rate (mL/h) = Dose (mg/min) x Volume (mL) / Concentration (mg)

Plugging in the given values, we get:

Infusion rate (mL/h) = 0.5 mg/min x 200 mL / 360 mg

Simplifying, we get:

Infusion rate (mL/h) = 100 mL / 360 min

Converting minutes to hours, we get:

Infusion rate (mL/h) = 100 mL / 6 h

Dividing both sides by 6, we get:

Infusion rate (mL/h) = 16.67 mL/h

Rounding to the nearest whole number, we get:

Infusion rate (mL/h) = 17 mL/h

Explanation

To calculate the infusion rate, we need to use the formula:

Infusion rate (mL/h) = Dose (mg/min) x Volume (mL) / Concentration (mg)

Plugging in the given values, we get:

Infusion rate (mL/h) = 2 mg/min x 60 min / 4 mg/mL

Simplifying, we get:

Infusion rate (mL/h) = 30 mL/h

Correct Answer is ["0.75"]

Explanation

To calculate the volume of interferon beta-1b solution, we need to use the formula:

Volume (mL) = Dose (mg) x Dilution factor (mL/mg)

The dilution factor is the ratio of the volume of sterile water to the amount of powder in the vial. In this case, it is 1.2 mL / 0.3 mg.

Plugging in the given values, we get:

Volume (mL) = 0.1875 mg x 1.2 mL / 0.3 mg

Simplifying, we get:

Volume (mL) = 0.75 mL
