and Roman Numerals
Question Stem:
A provider writes an order for XII acetaminophen tablets to be
dispensed for a client’s home supply. The nurse must verify the
quantity before release. How many tablets is this order in
Arabic numerals?
,Options:
A. 10 tablets
B. 11 tablets
C. 12 tablets
D. 15 tablets
Correct Answer: C. 12 tablets
Rationale:
Correct: XII = 10 + 1 + 1 = 12. The nurse should translate the
Roman numeral accurately before dispensing to prevent a
counting error.
A: X is 10, but this ignores the two I’s.
B: This is a common one-off error from misreading the final
numeral.
D: This incorrectly adds three extra units and is unsafe.
Teaching Point: Roman numerals must be translated exactly
before medication release.

2. Reference: Ch. 1 — Arithmetic Review — Arabic Numbers
and Roman Numerals
Question Stem:
A handwritten order states that the client should receive 29 mL
of an oral solution. The pharmacy label uses Roman numerals
for the dose quantity. Which Roman numeral represents 29?
,Options:
A. XXV
B. XXIX
C. XXXI
D. XLIX
Correct Answer: B. XXIX
Rationale:
Correct: 29 = 20 + 9 = XX + IX = XXIX. This is the correct
conversion of an Arabic number into Roman numerals.
A: XXV equals 25, which is too low.
C: XXXI equals 31, which is too high.
D: XLIX equals 49, not 29.
Teaching Point: Break Roman numerals into tens and ones for
accuracy.

3. Reference: Ch. 1 — Arithmetic Review — Arabic Numbers
and Roman Numerals
Question Stem:
A medication profile lists XLIV tablets as the quantity to be sent
to the unit. The nurse checks the order before administration.
How many tablets does XLIV represent?
, Options:
A. 34 tablets
B. 40 tablets
C. 44 tablets
D. 54 tablets
Correct Answer: C. 44 tablets
Rationale:
Correct: XL = 40 and IV = 4, so XLIV = 44. Accurate numeral
interpretation is part of safe medication verification.
A: 34 reflects a wrong subtraction and addition pattern.
B: 40 ignores the IV portion.
D: 54 incorrectly adds 10 too many.
Teaching Point: Roman numerals combine by subtraction and
addition, not guessing.
