Q1: Basic Oral Solid Conversion
A physician orders furosemide 60 mg orally daily. The pharmacy provides furosemide in 40
mg tablets. How many tablets should the nurse administer to the patient?
A) 1 tablet
B) 1.5 tablets
C) 2 tablets
D) 2.5 tablets
Correct Answer: B
Desired 60 mg
Rationale: Use the formula: × Quantity. Here, 40 mg × 1 tablet = 1.5 tablets
Have
Q2: Oral Liquid Measurement
The healthcare provider prescribes acetaminophen suspension 650 mg orally every 6 hours as
needed for pain. The label reads acetaminophen 160 mg / 5 mL. How many milliliters (mL)
should the nurse administer per dose? (Round to the nearest tenth).
A) 10.3 mL
B) 15.6 mL
C) 20.3 mL
D) 24.1 mL
Correct Answer: C
Desired 650 mg
Rationale: Use the standard calculation formula: × Volume = 160 mg × 5 mL =
Have
4.0625 × 5 = 20.3125 mL. Rounding to the nearest tenth yields 20.3 mL.

Q3: Weight-Based Pediatric/Adult Dosage
A patient weighing 154 lbs is prescribed a medication at a dose of 2 mg/kg/day divided into
two equal doses. How many milligrams (mg) should the patient receive per single dose?
A) 70 mg
B) 140 mg
C) 154 mg
D) 308 mg
Correct Answer: A
154 lbs
Rationale: First, convert pounds to kilograms: 2.2 lbs/kg = 70 kg. Next, calculate the
total daily dose: 70 kg × 2 mg/kg/day = 140 mg/day. Since the order specifies
140 mg
dividing this into two equal doses, divide the total daily dose by 2: = 70 mg per
2
single dose.
Q4: IV Drop Factor Calculation (gtt/min)
An intravenous solution of 1,000 mL 0.9% Normal Saline is ordered to infuse over 8 hours.
The drop factor of the manual IV tubing is 15 gtt/mL. At what rate should the nurse set the
manual infusion in drops per minute (gtt/min)? (Round to the nearest whole number).
A) 21 gtt/min
B) 31 gtt/min
C) 42 gtt/min
D) 50 gtt/min
Correct Answer: B
Total Volume (mL)×Drop Factor (gtt/mL)
Rationale: Use the IV flow rate formula: . Convert 8
Time in Minutes
1000 mL×15 gtt/mL 15000
hours to minutes: 8 × 60 = 480 minutes. Calculate: = =
480 min 480
31.25 gtt/min. Rounded to the nearest whole drop, this equals 31 gtt/min.

Q5: IV Pump Hourly Rate (mL/hr)
The healthcare provider orders 500 mL of Lactated Ringer's to infuse intravenously over 4
hours using an electronic volumetric infusion pump. At what hourly rate should the nurse
program the IV pump in mL/hr?
A) 100 mL/hr
B) 125 mL/hr
C) 150 mL/hr
D) 200 mL/hr
Correct Answer: B
Total Volume (mL) 500 mL
Rationale: Use the formula: Total Time (hours) = 4 hours = 125 mL/hr. IV pumps are
always set to track hourly fluid distribution volumes.
Q6: Heparin Continuous Infusion Math
A patient with a deep vein thrombosis is prescribed a continuous Heparin infusion at 1,200
units/hour. The pharmacy supplies a bag containing Heparin 25,000 units in 500 mL of 5%
Dextrose in Water (D5W). What hourly flow rate (mL/hr) should the nurse program into the
IV pump?
A) 12 mL/hr
B) 24 mL/hr
C) 36 mL/hr
D) 48 mL/hr
Correct Answer: B
Rationale: Calculate using the concentration ratio:
Desired Units/hr 1200 units/hr
× Total Volume (mL) = × 500 mL = 0.048 × 500 =
Available Units 25000 units
24 mL/hr
