A patient is ordered a continuous heparin infusion 18 units/kg/hr. The patient weighs 220 lbs. The medication is supplied as 25.000 units/250 ml. At what rate should the nurse set the pump?
The Correct Answer is ["18"]
To calculate the infusion rate, we'll follow these steps:
Convert patient weight to kilograms:
220 lbs ÷ 2.2 lbs/kg = 100 kg
Calculate desired heparin dose:
18 units/kg/hr × 100 kg = 1800 units/hr
Determine infusion rate in mL/hr:
(1800 units/hr) / (25000 units/250 mL) = 18 mL/hr

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 ["20"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Determine the required volume:
500 mg ÷ 125 mg/5 mL = 20 mL
