A patient weighing 60 kg is prescribed intravenous dopamine 4 micrograms/kg/minute. Calculate the infusion rate in mL/hour. (Stock = dopamine 200 mg in 50 mL glucose 5%).

Here are the solutions to the questions: 4. A patient weighing 60 kg is prescribed intravenous dopamine 4 micrograms/kg/minute. Calculate the infusion rate in mL/hour. (Stock = dopamine 200 mg in 50 mL glucose 5%). Step 1: Calculate the total dopamine dose per minute for the patient. Dose per minute = 4 kg · min × 60 kg = 240 min Step 2: Convert the dose from micrograms per minute to milligrams per hour. Dose per hour = 240 min × 1 mg1000 × 60 min1 hr Dose per hour = (240 × 60)/(1000) mghr = (14400)/(1000) mghr = 14.4 mghr Step 3: Determine the concentration of the stock solution. Concentration = 200 mg50 mL = 4 mgmL Step 4: Calculate the infusion rate in mL/hour. Infusion rate = Dose per hourConcentration = 14.4 mghr4 mgmL Infusion rate = 3.6 mLhr The correct option is B. The infusion rate is 3.6 mL/hour. 5. The procedure which is used to prove that the various production procedures, equipment and materials will produce accurate results is known as: The correct option is D. Validation is the documented act of proving that any procedure, process, equipment, material, activity, or system actually leads to the expected results. This directly matches the description of proving that production procedures, equipment, and materials will produce accurate results. The correct answer is D. Validation. What's next?
