1. A provider orders cefazolin 500 mg IV every 8 hours. The available vial is
labeled 1-gram powder. Directions state: "Reconstitute with 2.5 mL sterile
water to yield a concentration of 330 mg/milk" How many mL should the nurse
administer per dose?
A. 0.8 mL
B. 1.0 mL
C. 1.5 mL
D. 2.0 mL
**CORRECT ANSWER: C. 1.5 mL**
Rationale: Desired dose = 500 mg. Concentration = 330 mg/milk
Volume = 500 mg / 330 mg/mL = 1.515 ≈ 1.5 milk
2. A patient is prescribed heparin 25,000 units in 500 mL D5W to infuse at
1,200 units/hr. Calculate the infusion rate in mL/hr.
A. 20 mL/hr.
B. 24 mL/hr.
C. 30 mL/hr.
D. 36 mL/hr.
, **CORRECT ANSWER: B. 24 mL/hr.**
Rationale: Concentration = 25,000 units / 500 mL = 50 units/milk
Rate = 1,200 units/hr. / 50 units/mL = 24 mL/hr.
3. Order: dopamine 5 mcg/kg/min IV. Patient weighs 176 lb. Available: dopamine
800 mg in 500 mL D5W. What is the infusion rate in mL/hr.?
A. 10 mL/hr.
B. 12 mL/hr.
C. 15 mL/hr.
D. 18 mL/hr.
**CORRECT ANSWER: C. 15 mL/hr.**
Rationale: Weight = 176 lb. / 2.2 = 80 kg. Dose = 5 mcg/kg/min × 80 kg = 400 mcg/min = 0.4 mg/min.
Concentration = 800 mg / 500 mL = 1.6 mg/milk Infusion rate = 0.4 mg/min / 1.6 mg/mL = 0.25
mL/min × 60 = 15 mL/hr.
4. A child weighs 44 lb. The order is amoxicillin 20 mg/kg/day divided every
12 hours. How many mgs should the nurse give per dose? (Round to nearest
whole number)
A. 200 mg
B. 300 mg
C. 400 mg
D. 500 mg
**CORRECT ANSWER: A. 200 mg**
Rationale: Weight = 44 lb. / 2.2 = 20 kg. Daily dose = 20 mg/kg × 20 kg = 400 mg/day.
, Divided q12h = 400 mg / 2 = 200 mg/dose.
5. A patient is to receive 1 L of NS over 8 hours. The drop factor is 15 got/milk
Calculate the flow rate in got/min.
A. 21 got/min
B. 25 got/min
C. 31 got/min
D. 42 got/min
**CORRECT ANSWER: C. 31 got/min**
Rationale: Volume = 1000 mL, time = 8 hr. = 480 min.
got/min = (1000 mL × 15 got/mL) / 480 min = = 31.25 ≈ 31 got/min.
6. Order: morphine sulfate 4 mg IV push. Available: 10 mg/milk How many mL will
the nurse administers?
A. 0.2 mL
B. 0.4 mL
C. 0.6 mL
D. 0.8 mL
**CORRECT ANSWER: B. 0.4 mL**
Rationale: 4 mg / (10 mg/mL) = 0.4 milk
7. A patient is receiving IV fluids at 125 mL/hr. How many liters will the?
patient receive in 24 hours?
A. 2 L
