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 ["0.4"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Convert the ordered dose to grams:
250 mg ÷ 1000 mg/g = 0.25 g
Determine the required volume:
0.25 g ÷ 6 g/10 mL = 0.42 mL
Round off to the nearest tenth: 0.4 mL
Correct Answer is ["539"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Convert patient weight to kilograms:
158 lbs ÷ 2.2 lbs/kg = 71.8 kg
Determine the total daily dosage:
15 mg/kg/day × 71.8 kg = 1077 mg/day
Calculate the dosage per dose:
1077 mg/day ÷ 2 doses = 538. 5mg/dose
Round to the nearest whole number: 539 mg
