A patient is ordered heparin IV at 1100 units/hr. The concentration of heparin is 25.000 units/250 mL. At what rate should the nurse set the pump?
The Correct Answer is ["11"]
To calculate the infusion rate, we'll follow these steps:
Determine the infusion rate in units/mL:
25000 units ÷ 250 mL = 100 units/mL
Calculate the infusion rate in mL/hr:
1100 units/hr ÷ 100 units/mL = 11 mL/hr

Correct Answer is ["12.8"]
Explanation
To calculate the infusion rate, we'll follow these steps:
Convert patient weight to kg:
176 lbs ÷ 2.2 lbs/kg = 80 kg
Calculate desired heparin dose:
16 units/kg/hr × 80 kg = 1280 units/hr
Determine infusion rate in mL/hr:
(1280 units/hr) / (50000 units/500 mL) = 12.8 mL/hr
Correct Answer is ["260"]
Explanation
To calculate the total fluid intake, we'll need to convert all the volumes to a common unit (mL).
Juice:
½ cup = 120 mL (assuming a standard 8-ounce cup)
Gelatin:
3 oz = 90 mL (1 ounce is approximately 30 mL)
Ice pop:
1 oz = 30 mL
Ginger ale:
20 mL
Total intake:
120 mL + 90 mL + 30 mL + 20 mL = 260 mL
