Question: A provider prescribes vitamin D XII mcg orally once
daily. The nurse must document the dose in Arabic numerals
before administration. What dose should the nurse record?
Options:
A. 10 mcg
B. 11 mcg
,C. 12 mcg
D. 20 mcg
Correct Answer: C. 12 mcg
Rationale: Correct: XII equals 12. In medication documentation,
Roman numerals must be converted accurately to avoid a
tenfold or other dosing error. A: 10 confuses XII with X. B: 11 is
one less than the correct conversion. D: 20 is not the value of
XII and would be unsafe.
Teaching Point: Convert Roman numerals before documenting
or administering medication.

Question: A medication label reads morphine sulfate IV mg.
The provider’s order matches the label exactly, but the nurse
must interpret the Roman numeral before checking the dose.
What dose is written on the label?
Options:
A. 2 mg
B. 4 mg
C. 6 mg
D. 14 mg
Correct Answer: B. 4 mg
Rationale: Correct: IV equals 4. Accurate numeral conversion is
part of basic medication safety because small errors can change
the prescribed dose. A: 2 reflects II, not IV. C: 6 reflects VI, not
IV. D: 14 is XIV, not IV.
,Teaching Point: Roman numeral IV always equals 4.

Question: A patient is prescribed 3/4 tablet of a medication
twice daily. How many tablets does the patient receive in 1
day?
Options:
A. 1 tablet
B. 1.25 tablets
C. 1.5 tablets
D. 2 tablets
Correct Answer: C. 1.5 tablets
Rationale: Correct: Multiply 3/4 tablet × 2 doses/day = 6/4 =
1.5 tablets/day. The dose is doubled because the medication is
taken twice daily. A: 1 tablet underestimates the daily total. B:
1.25 tablets reflects an incorrect fraction calculation. D: 2
tablets is too high and would be unsafe.
Teaching Point: Multiply the dose by the number of daily
administrations.

Question: A provider orders 2/5 tablet of a sedative 3 times per
day. The nurse calculates the total tablet amount for 1 day.
What is the total daily dose?
, Options:
A. 3/5 tablet
B. 6/5 tablets
C. 1 tablet
D. 2 tablets
Correct Answer: B. 6/5 tablets
Rationale: Correct: 2/5 × 3 = 6/5, which is 1.2 tablets per day.
This is the correct daily total before any rounding or practical
dispensing considerations. A: 3/5 tablet results from multiplying
incorrectly by 1. C: 1 tablet is too low. D: 2 tablets is too high.
Teaching Point: Keep fractions exact until the final step.

Reference: Ch. 1 — Fractions — Dividing Fractions
Question: A child is prescribed 3/4 mL of an oral medication to
be given in 2 equal doses. What volume should the nurse give
for each dose? Round to the nearest hundredth if needed.
Options:
A. 0.25 mL
B. 0.33 mL
C. 0.38 mL
D. 0.50 mL
Correct Answer: C. 0.38 mL
Rationale: Correct: 3/4 ÷ 2 = 3/8 = 0.375 mL, which rounds to
0.38 mL. The total dose is divided equally between two
administrations. A: 0.25 mL is too low and equals 1/4 mL. B:
0.33 mL is an incorrect approximation of 1/3. D: 0.50 mL would
