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 ["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 ["7.5"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Determine the total medication dose:
0.1 units/kg × 75 kg = 7.5 units
Calculate the volume to be administered:
7.5 units ÷ 100 units/100 mL = 7.5 mL
