Question 1:
A patient is ordered a continuous heparin infusion at 16 units/kg/hr. The patient
weighs 176lbs. Heparin is supplied in 50000 units/500mL. At what rate will the
nurse set the pump?
Explanation
Correct Answer: 12.8
1. Convert pounds to kilograms:
176 lbs/2.20462 kg =80 kg
2. Calculate the desired heparin infusion rate:
16 units/kg/hr x 80kg = 1280 units/hr
3. Determine the concentration of heparin in the solution:
50000 units / 500 mL = 100 units/mL
4. Calculate the infusion rate in millilitres per hour:
1280 units/hr / 100 units/mL =12.8 mL/hr

Question 2:
A patient is ordered medication 100units/kg SQ. The medication is supplied in
10000 units/mL The patient weighs 220 lbs. What should the nurse administer?
Explanation
Correct Answer: 1
Let's calculate the dosage step-by-step:
1. Convert pounds to kilograms:
220 lbs/2.20462 kg = 99.8 kg
2. Calculate the total dosage:
100 units/kg x 99.8 kg = 9980units
3. Determine the concentration of the medication:
10000 units/mL
4. Calculate the volume needed:
9980 units / 10000 units/mL = 1 mL

Question 3:
A nurse is calculating the intake of a client during the past 9 hrs. The client's
intake includes lactated Ringer's IV at 150ml/hr, cefazolin 2g IV intermittent
bolus in 100ml of 0.9% sodium chloride, two units of packed RBCs of 275ml and
250ml, two IV infusions of 250ml 0.9% sodium chloride, Ranitidine 50mg IV
intermittent bolus in 50ml dextrose 5% in water. How many ml of intake should
the nurse record?
Explanation
Correct Answer: 2525
Here's the calculation of the total intake:
IV fluids:
Lactated Ringer's IV: 150 ml/hr x 9 hrs = 1350 ml
Cefazolin: 100 ml
0.9% sodium chloride (2 units): 250 ml x 2 = 500 ml
Ranitidine: 50 ml
Packed RBCs:
275 ml + 250 ml = 525 ml
Total intake:
1350 ml + 100 ml + 500 ml + 50 ml + 525 ml = 2525 ml
