Final answer:
To set the controller to the appropriate rate for the Cerebyx 100 PE IVPB order, you should set it to 0.28 ml/hour.
Step-by-step explanation:
To calculate the milliliters per hour, we need to convert the infusion rate from milliliters per minute to milliliters per hour. Since we want to infuse at a rate of 150 PE per minute, we divide that by the total volume of 50 ml to find the concentration: 150 PE/minute ÷ 50 ml = 3 PE/ml.
To convert this to milliliters per hour, we multiply by 60: 3 PE/ml × 60 minutes = 180 PE/ml per hour. Finally, to find the milliliters per hour, we divide the total volume (50 ml) by the concentration (180 PE/ml per hour): 50 ml ÷ 180 PE/ml per hour = 0.28 ml/hour.
