Q1. A patient weighs 154 lb. Convert this weight to kilograms. Round to the nearest
tenth.

A. 68.2 kg
B. 69.9 kg
C. 70.0 kg [CORRECT]
D. 71.5 kg

Rationale: 154 lb ÷ 2.2 = 70.0 kg exactly. A uses 2.26 conversion; B rounds
incorrectly; D uses 2.15 conversion.
Correct Answer: C




Q2. The physician orders 0.5 g of a medication. The available tablets are 250 mg
each. How many tablets should the nurse administer?

A. 0.5 tablets
B. 1 tablet
C. 2 tablets [CORRECT]
D. 4 tablets

Rationale: 0.5 g = 500 mg; 500 mg ÷ 250 mg/tablet = 2 tablets. A fails to convert
grams to milligrams; B gives half the correct dose; D doubles the conversion.
Correct Answer: C

,Q3. A medication is ordered as 2.5 mL. The syringe is calibrated in minims. How many
minims equal 2.5 mL? (1 mL = 15 minims)

A. 12.5 minims
B. 30 minims
C. 37.5 minims [CORRECT]
D. 45 minims

Rationale: 2.5 mL × 15 minims/mL = 37.5 minims. A divides instead of multiplies; B
uses 12 minims/mL (V2 trap); D uses 18 minims/mL.
Correct Answer: C




Q4. Convert 3 tablespoons to milliliters.

A. 30 mL
B. 36 mL
C. 45 mL [CORRECT]
D. 60 mL

Rationale: 1 tablespoon = 15 mL; 3 × 15 = 45 mL. A uses 10 mL/tbsp (V2 household
confusion); B uses 12 mL/tbsp; D uses 20 mL/tbsp (teaspoon confusion).
Correct Answer: C




Q5. The order reads: "Give gr 1/150 of atropine sulfate." The available concentration
is 0.4 mg/mL. How many mL should the nurse administer? (1 gr = 60 mg)

A. 0.25 mL
B. 0.5 mL
C. 1.0 mL [CORRECT]
D. 1.5 mL

,Rationale: 1/150 gr = 60/150 = 0.4 mg; 0.4 mg ÷ 0.4 mg/mL = 1.0 mL. A uses 1 gr =
65 mg; B calculates 1/300 gr; D uses 1 gr = 64 mg.
Correct Answer: C




Q6. A patient is to receive 0.125 mg of digoxin. The available elixir is 0.05 mg/mL.
How many mL should the nurse administer?

A. 1.5 mL
B. 2.0 mL
C. 2.5 mL [CORRECT]
D. 3.0 mL

Rationale: 0.125 mg ÷ 0.05 mg/mL = 2.5 mL. A inverts the fraction; B rounds down
incorrectly; D adds an extra 0.5 mL.
Correct Answer: C




Q7. Convert 2.5 L to milliliters.

A. 25 mL
B. 250 mL
C. 2,500 mL [CORRECT]
D. 25,000 mL

Rationale: 1 L = 1,000 mL; 2.5 × 1,000 = 2,500 mL. A moves decimal one place; B
moves decimal two places; D moves decimal four places.
Correct Answer: C




Q8. A medication is ordered as 7.5 grains. Convert to milligrams. (1 gr = 60 mg)

A. 420 mg
B. 450 mg [CORRECT]

, C. 480 mg
D. 500 mg

Rationale: 7.5 gr × 60 mg/gr = 450 mg. A uses 56 mg/gr; C uses 64 mg/gr (V1 trap:
confusing with 1 gr = 64.8 mg); D rounds up incorrectly.
Correct Answer: B




Q9. The physician orders 0.3 mg of a medication. The available tablets are 150 mcg
each. How many tablets should the nurse administer?

A. 1 tablet
B. 2 tablets [CORRECT]
C. 3 tablets
D. 4 tablets

Rationale: 0.3 mg = 300 mcg; 300 mcg ÷ 150 mcg/tablet = 2 tablets. A fails to
convert mg to mcg; C triples the dose; D uses 75 mcg/tablet.
Correct Answer: B




Q10. Convert 45 inches to centimeters. (1 inch = 2.54 cm)

A. 104.3 cm
B. 110.3 cm
C. 114.3 cm [CORRECT]
D. 120.3 cm

Rationale: 45 × 2.54 = 114.3 cm. A uses 2.32 cm/inch; B uses 2.45 cm/inch; D uses
2.67 cm/inch.
Correct Answer: C




Q11. A patient needs 0.75 g of a medication. The available capsules are 250 mg each.
How many capsules should the nurse administer?
