Question

A solution consisting of 182 mg of dopamine in 26 mL of solution is administered at a rate of 10 ​mL/hr. Complete parts​ (a) and​ (b) below

What is the flow rate in mg of dopamine per​ hour?
. If a patient is prescribed to receive 140 mg of dopamine​, how long should the infusion​ last?

Answer 1

The correct answer is A. 70 mg and B. 2 hours.

Explanation:

A. Let's calculate the flow rate of dopamine per hour:

Flow rate of dopamine per hour = (182 * 10)/26

Flow rate of dopamine per hour = 1,820/26

Flow rate of dopamine per hour = 70 mg

B. Let's calculate how much the solution should last for a patient that is prescribed to receive 140 mg of dopamine

Prescription = 140 mg

Flow rate of dopamine per hour = 70 mg

Duration = Prescription/Flow rate of dopamine per hour

Duration = 140/70

Duration = 2 hours
