Final answer:

To administer noradrenaline at 0.05 mcg/kg/min to a 65 kg patient with a solution of 8 mg in 50 mL, the infusion pump should be set to 1.22 mL/hr after performing the necessary calculations.

Step-by-step explanation:

To calculate the infusion rate in mL/hr for noradrenaline at 0.05 mcg/kg/min for a patient weighing 65 kg, with an infusion solution containing 8 mg of noradrenaline in 50 mL, use the following steps:

  1. Calculate the patient's dose in mcg/min: 0.05 mcg/kg/min × 65 kg = 3.25 mcg/min.
  2. Convert the dose to mg/hr (since the vial is in mg): 3.25 mcg/min × 60 min/hr = 195 mcg/hr, which is equivalent to 0.195 mg/hr.
  3. Calculate the concentration of the solution: 8 mg/50 mL = 0.16 mg/mL.
  4. Determine how many mL/hr needed to deliver 0.195 mg/hr: 0.195 mg/hr ÷ 0.16 mg/mL = 1.21875 mL/hr.

Therefore, you would set the infusion pump at 1.22 mL/hr (rounding to the nearest hundredth).
