1. Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Question: A nurse is reviewing a medication supply record
that lists XIV tablets in a sealed packet. What Arabic
number does XIV represent?
Options:
A. 12
B. 14
C. 16
, D. 24
Correct Answer: B. 14
Rationale — Correct: In Roman numerals, X = 10 and IV = 4
because I before V means subtraction. So 10 + 4 = 14.
Rationale — Incorrect Options:
A. 12 results from subtracting too much or misreading the
symbols.
C. 16 incorrectly adds all symbols as if IV were 6.
D. 24 reflects doubling the value of XII rather than
converting XIV.
Teaching Point: Roman numeral subtraction changes the
value of adjacent symbols.

2. Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Question: A pharmacy label shows that 68 tablets remain
in stock. What is the correct Roman numeral for 68?
Options:
A. LXV
B. LXVIII
C. LXXVIII
D. XLVIII
Correct Answer: B. LXVIII
Rationale — Correct: 60 = LX and 8 = VIII, so 68 = LXVIII.
The symbols must be combined in descending order.
Rationale — Incorrect Options:
, A. LXV equals 65, which is 3 less than 68.
C. LXXVIII equals 78, which is too high.
D. XLVIII equals 48, not 68.
Teaching Point: Build Roman numerals from largest value
to smallest value.

3. Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Question: A nurse reads a supply count written as 49 on a
medication bin. Which Roman numeral is correct?
Options:
A. XLIX
B. XLV
C. IL
D. LIX
Correct Answer: A. XLIX
Rationale — Correct: 40 = XL and 9 = IX, so 49 = XLIX.
Roman numerals use subtraction only in specific
combinations.
Rationale — Incorrect Options:
B. XLV equals 45, which is 4 too low.
C. IL is not a standard Roman numeral form.
D. LIX equals 59, which is 10 too high.
Teaching Point: Use standard subtractive forms only: IV, IX,
XL, XC, CD, CM.

4. Reference: Ch. 1 — Multiplying Fractions
Question: A nurse prepares a liquid supplement and needs
to calculate 3/4 × 2/5 of a measured amount. What is the
product in simplest form?
Options:
A. 1/2
B. 3/10
C. 5/8
D. 6/10
Correct Answer: B. 3/10
Rationale — Correct: Multiply numerators and
denominators: 3 × 2 = 6 and 4 × 5 = 20, giving 6/20, which
simplifies to 3/10. Simplifying before or after multiplication
gives the same answer.
Rationale — Incorrect Options:
A. 1/2 is too large and comes from an incorrect
simplification.
C. 5/8 is not the product of these fractions.
D. 6/10 is equivalent to 3/5, not the simplified product.
Teaching Point: Multiply straight across, then reduce the
fraction.
