A patient is ordered 40 unit/kg IV bolus of Heparin. The patient weighs 154 lbs. Heparin is supplied 25.000 units/250 mL. How many mL will the nurse administer?
The Correct Answer is ["2.8"]
To calculate the medication dosage, we'll follow these steps:
Convert patient weight to kilograms:
154 lbs ÷ 2.2046 lbs/kg = 69.84 kg
Determine the total medication dose:
40 units/kg × 69.84 kg = 2793.6 units
Calculate the volume to be administered:
2793.6 units ÷ 25000 units/250 mL = 2.8 mL

Correct Answer is ["1.7"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Convert patient weight to kilograms:
121 lbs ÷ 2.2 lbs/kg = 55 kg
Determine the total daily dosage:
2.5 mg/kg/day × 55 kg = 137.5 mg/day
Calculate the dosage per dose:
137.5mg/day ÷ 2 doses = 68.75 mg/dose
Determine the volume to be administered:
68.75 mg ÷ 40 mg/mL = 1.7 mL
Correct Answer is ["2525"]
Explanation
To calculate the total intake, we'll add up the volumes of all fluids the client received during the past 9 hours:
Lactated Ringer's IV:
150 mL/hr × 9 hrs = 1350 mL
Cefazolin:
100 mL (intermittent bolus)
Packed RBCs:
250 mL +275 mL = 525 mL
IV bolus infusions:
2 × 250 mL = 500 mL
Ranitidine:
50 mL (intermittent bolus)
Total intake:
1350 mL + 100 mL + 525 mL + 500 mL + 50 mL = 2520 mL
