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?
Accepted Solution
A:
Answer:The correct answer is A. 70 mg and B. 2 hours.Step-by-step explanation:A. Let's calculate the flow rate of dopamine per hour:Flow rate of dopamine per hour = (182 * 10)/26Flow rate of dopamine per hour = 1,820/26Flow rate of dopamine per hour = 70 mgB. Let's calculate how much the solution should last for a patient that is prescribed to receive 140 mg of dopaminePrescription = 140 mgFlow rate of dopamine per hour = 70 mgDuration = Prescription/Flow rate of dopamine per hour Duration = 140/70Duration = 2 hours
