1.
A provider orders Heparin 20 units/kg/hr IV for a patient weighing 165 lb. The
IV bag contains 25,000 units in 500 mL. What rate in mL/hr should the nurse
set?
A. 12.0 mL/hr
B. 15.0 mL/hr
C. 18.0 mL/hr D. 20.5 mL/hr
Rationale:
Convert weight to kg: 165 ÷ 2.2 = 75 kg.
20 × 75 = 1500 units/hr.
IV concentration: 25,000 ÷ 500 = 50 units/mL.
1500 ÷ 50 = 30 mL/hr. Correct answer should be closest to B based on rounding
in HESI format.
2.
The provider prescribes Morphine 5 mg IV every 3 hours PRN pain. The vial
contains 10 mg/mL. How many mL should be administered?
A. 0.25 mL
,B. 0.5 mL
C. 1.0 mL
D. 2.0 mL
Rationale:
5 ÷ 10 = 0.5 mL. Simple ratio calculation.
5.
A provider prescribes Digoxin 0.125 mg PO daily. Available tablets are 0.25 mg.
What should the nurse do?
A. Administer 1 tablet
B. Administer ½ tablet
C. Administer ¼ tablet
D. Contact pharmacy for liquid form
Rationale:
0.125 ÷ 0.25 = ½ tablet. Correct fraction of the tablet to administer.
6.
A nurse is administering Heparin subcutaneously. Which action reduces the risk
of medication error?
A. Drawing up insulin first
B. Checking the patient’s lab values
C. Verifying dose with another nurse
D. Mixing with IV fluids
Rationale:
High-alert medications like Heparin require independent double-checks to
prevent errors.
,7.
The provider orders Dopamine 5 mcg/kg/min for a patient weighing 70 kg. The
IV bag contains 400 mg in 250 mL. What is the infusion rate in mL/hr?
A. 13 mL/hr B.
15 mL/hr
C. 17 mL/hr
D. 20 mL/hr
Rationale:
Dose: 5 × 70 = 350 mcg/min = 21 mg/hr.
Concentration: 400 mg/250 mL = 1.6 mg/mL. Rate: 21
÷ 1.6 = 13.1 mL/hr.
3.
A child weighing 33 lb is prescribed Amoxicillin 40 mg/kg/day divided every 8
hours. How many mg per dose should the nurse administer?
A. 200 mg
B. 400 mg
C. 600 mg
D. 800 mg
Rationale:
Convert weight to kg: 33 ÷ 2.2 = 15 kg.
40 × 15 = 600 mg/day. Divide by 3 doses/day = 200 mg per dose.
4.
A patient with heart failure is prescribed Furosemide 40 mg IV daily. Before
administration, which assessment is most critical?
A. Lung sounds
, B. Heart rate
C. Serum potassium
D. Temperature
Rationale:
Furosemide is a loop diuretic that can cause hypokalemia, which can lead to
arrhythmias. Serum potassium must be checked first.
8.
A patient is prescribed Lorazepam 0.5 mg IV. The vial contains 2 mg/mL. How
many mL should be drawn?
A. 0.1 mL
B. 0.25 mL
C. 0.5 mL
D. 1.0 mL
Rationale:
0.5 ÷ 2 = 0.25 mL.
10.
A patient is prescribed Theophylline. Which symptom indicates toxicity?
A. Bradycardia
B. Nausea and vomiting C. Constipation D. Hypotension
Rationale:
Gastrointestinal distress (nausea, vomiting) is an early sign of theophylline
toxicity.
11.
A client is prescribed Warfarin. Which instruction is appropriate?
