1) Arabic Numbers and Roman Numerals
Reference: Ch. 1 — Arithmetic Review — Arabic Numbers and
Roman Numerals
Stem: A medication profile lists a dose as XIV mg. The nurse
must convert the dose to Arabic numerals before
administration. What dose should the nurse give?
Options:
,A. 4 mg
B. 14 mg
C. 16 mg
D. 40 mg
Correct Answer: B
Rationale: B is correct because X = 10 and IV = 4, so XIV = 14
mg. This is an exact numeral conversion, so no rounding is
involved. A reflects only the “IV” value. C adds instead of
subtracting. D misreads the numeral as XL-like placement.
Teaching Point: Roman numerals use subtraction only when a
smaller value precedes a larger one.

2) Arabic Numbers and Roman Numerals
Reference: Ch. 1 — Arithmetic Review — Arabic Numbers and
Roman Numerals
Stem: A charted medication quantity reads 9 tablets. The nurse
is asked to record the quantity using Roman numerals. Which
entry is correct?
Options:
A. VIII
B. IX
C. XI
D. XV
Correct Answer: B
,Rationale: B is correct because 9 = IX. The nurse must convert
accurately to prevent documentation errors. A equals 8, C
equals 11, and D equals 15.
Teaching Point: Convert exactly; one numeral error can change
the documented dose.

3) Multiplying Fractions
Reference: Ch. 1 — Arithmetic Review — Fractions —
Multiplying Fractions
Stem: A provider orders 3/4 tablet twice daily. The nurse is
calculating the total number of tablets the patient will take in 1
day. How many tablets should the patient receive in 24 hours?
Options:
A. 1 1/4 tablets
B. 1 1/2 tablets
C. 1 3/4 tablets
D. 2 tablets
Correct Answer: B
Rationale: B is correct because 3/4 tablet/dose × 2 doses/day =
6/4 tablets/day = 1 1/2 tablets/day. The dose units cancel,
leaving tablets per day. A is too low and results from adding
incorrectly. C and D overestimate the total.
Teaching Point: Multiply fractions directly and simplify before
reporting the final amount.

4) Multiplying Fractions
Reference: Ch. 1 — Arithmetic Review — Fractions —
Multiplying Fractions
Stem: The label reads 300 mg per tablet. A provider orders 2/3
of a tablet for the patient. How many milligrams will the patient
receive?
Options:
A. 100 mg
B. 150 mg
C. 200 mg
D. 225 mg
Correct Answer: C
Rationale: C is correct because 300 mg/tablet × 2/3 tablet =
200 mg. The tablet unit cancels, leaving milligrams. A and B
reflect under-calculation, and D is not the correct fraction of
300.
Teaching Point: Cancel units first; the remaining unit identifies
the final dose.
