1. A provider orders Heparin 8,000 units subcutaneously every 12 hours. The pharmacy
provides a vial labeled Heparin 10,000 units/mL. How many milliliters (mL) should the nurse
administer per dose?
A. 0.4 mL
B. 0.8 mL
C. 0.6 mL
D. 1.2 mL
Answer: B
Rationale: To calculate the dose, use the formula (Desired/Have) x Quantity. In this case,
(8,000 units / 10,000 units) x 1 mL equals 0.8 mL. Always ensure the units match before
performing the final division.
2. The healthcare provider orders 1,000 mL of 0.9% Normal Saline to infuse over 8 hours. At
what rate in mL/hr should the nurse set the infusion pump?
A. 100 mL/hr
B. 125 mL/hr
C. 150 mL/hr
,D. 175 mL/hr
Answer: B
Rationale: Divide the total volume of 1,000 mL by the total time of 8 hours. 1,000 divided
by 8 results in a flow rate of 125 mL per hour. This standard calculation ensures the patient
receives the correct volume over the specified timeframe.
3. A pediatric patient weighing 44 lbs is prescribed Cefazolin 25 mg/kg/day IV divided into
four equal doses. How many milligrams (mg) will the nurse administer per single dose?
A. 100 mg
B. 250 mg
C. 500 mg
D. 125 mg
Answer: D
Rationale: First, convert the weight to kilograms by dividing 44 lbs by 2.2, which equals 20
kg. Multiply 20 kg by 25 mg/kg to find the total daily dose of 500 mg. Finally, divide the
total daily dose by 4 doses to get 125 mg per dose.
4. An order reads: Infuse 500 mL of D5W over 4 hours using a drop factor of 15 gtt/mL.
Calculate the drip rate in gtt/min (round to the nearest whole number).
A. 31 gtt/min
B. 28 gtt/min
, C. 35 gtt/min
D. 42 gtt/min
Answer: A
Rationale: Use the formula (Volume in mL / Time in minutes) x Drop Factor. This
calculation is (500 mL / 240 min) x 15 gtt/mL, which equals 31.25. Rounding to the nearest
whole number gives 31 gtt/min.
5. The order is for Digoxin 0.25 mg PO daily. The available tablets are 125 mcg each. How
many tablets should the nurse administer?
A. 0.5 tablet
B. 2 tablets
C. 1 tablet
D. 1.5 tablets
Answer: B
Rationale: First, convert milligrams to micrograms by multiplying 0.25 mg by 1,000,
resulting in 250 mcg. Then, divide the desired dose of 250 mcg by the available strength of
125 mcg. The result is 2 tablets per dose.
