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 ["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
Correct Answer is ["115"]
Explanation
To determine the IV pump rate, let’s follow these steps:
Reconstitute the medication:
The concentration after reconstitution is 1 Gm/10 mL.
Since 1 Gm = 1000 mg, the concentration is 100 mg/mL.
Calculate the volume needed for the required dose:
The patient needs 1500 mg.
Using the concentration, calculate the volume: 1500/100= 15 mL
Further dilute the medication:
Add the 15 mL of reconstituted medication to 100 mL of normal saline solution (NSS).
Total volume to be infused = 15 mL + 100 mL = 115 mL.
Set the IV pump rate:
The medication is to be infused over one hour.
Therefore, the IV pump rate is: 115/1= 115 mL/ hr
