Introduction
This comprehensive dosage calculation examination assesses the
mathematical competency and clinical judgment required for safe
medication administration in nursing practice. The questions
evaluate understanding of metric and household conversions, oral
and parenteral dose calculations, intravenous flow rates, pediatric
weight-based dosing, and reconstitution procedures. The
multiple-choice and scenario-based structure emphasizes real-
world application, dimensional analysis, and error prevention,
ensuring candidates can calculate accurate medication doses and
infusion rates to protect patient safety and promote positive
outcomes. Each question includes verified answers with detailed
step-by-step rationales to reinforce sound clinical calculation
skills.
SECTION ONE: QUESTIONS 1–100
,1. The provider orders 0.5 g of a medication. The pharmacy
sends 250 mg tablets. How many tablets will the nurse
administer?
A. 0.5 tablet
B. 1 tablet
C. 2 tablets
D. 3 tablets
C. 2 tablets
RATIONALE: Convert 0.5 g to mg: 0.5 × 1,000 = 500 mg. Use
the formula Desired ÷ Available × Quantity: 500 mg ÷ 250 mg ×
1 tablet = 2 tablets.
2. A client is prescribed 8 ounces of water. How many
milliliters should the nurse document?
A. 120 mL
B. 240 mL
C. 360 mL
D. 480 mL
B. 240 mL
RATIONALE: One ounce equals 30 mL. Therefore, 8 oz × 30
mL/oz = 240 mL.
3. Convert 0.6 grams to milligrams.
A. 6 mg
B. 60 mg
,C. 600 mg
D. 6,000 mg
C. 600 mg
RATIONALE: To convert grams to milligrams, multiply by
1,000. 0.6 × 1,000 = 600 mg.
4. The provider orders 750 mg of a medication. Available
tablets contain 250 mg each. How many tablets should the
nurse administer?
A. 1 tablet
B. 2 tablets
C. 3 tablets
D. 4 tablets
C. 3 tablets
RATIONALE: Use the formula Desired ÷ Available × Quantity:
750 mg ÷ 250 mg × 1 tablet = 3 tablets.
5. Convert 2.4 g to milligrams.
A. 24 mg
B. 240 mg
C. 2,400 mg
D. 24,000 mg
C. 2,400 mg
RATIONALE: To convert grams to milligrams, multiply by
1,000. 2.4 × 1,000 = 2,400 mg.
, 6. A client with a body surface area (BSA) of 1.85 m² is
prescribed doxorubicin 60 mg/m² intravenously. How
many milligrams should the nurse administer?
A. 60 mg
B. 111 mg
C. 120 mg
D. 150 mg
B. 111 mg
RATIONALE: Multiply the BSA by the prescribed dose per m²:
1.85 m² × 60 mg/m² = 111 mg.
7. The provider orders 1.25 g of a medication. The
pharmacy only has 500 mg tablets available. How many
tablets should the nurse administer?
A. 1.5 tablets
B. 2 tablets
C. 2.5 tablets
D. 3 tablets
C. 2.5 tablets
RATIONALE: Convert 1.25 g to mg: 1.25 × 1,000 = 1,250 mg.
Then use Desired ÷ Available × Quantity: 1,250 mg ÷ 500 mg ×
1 tablet = 2.5 tablets.
8. Convert 500 mcg to milligrams.
A. 0.05 mg
B. 0.5 mg
C. 5 mg
D. 50 mg
