Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Stem: The nurse is reviewing an old chart that documents a
client’s previous procedure as XIV years ago. What number
should the nurse enter in Arabic numerals?
Options:
A. 12
B. 14
C. 16
D. 18
,Correct Answer: B. 14
Rationales:
Correct answer: XIV = 10 + 4 = 14. The nurse should convert
each Roman numeral by value and combine them using
standard subtraction rules.
A: 12 incorrectly treats XIV as XII.
C: 16 incorrectly adds the 10 and 4 as if IV were 6.
D: 18 is not represented by XIV.
Teaching Point: Roman numerals use subtraction when a
smaller numeral precedes a larger one.

Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Stem: A client’s historical record lists a prior surgery date as the
year 47 in Roman numerals. Which entry is correct?
Options:
A. XLV
B. XLVII
C. XLIX
D. LIV
Correct Answer: B. XLVII
Rationales:
Correct answer: 47 = 40 + 7 = XLVII. The nurse converts 40 as XL
and adds VII for 7.
A: XLV equals 45.
C: XLIX equals 49.
D: LIV equals 54.
,Teaching Point: Break Roman numerals into tens and ones for
accurate conversion.

Reference: Ch. 1 — Multiplying Fractions
Stem: The provider orders 3/4 tablet of a medication twice
daily. The nurse is calculating the total tablets the client takes
per dose across 2 doses. How many tablets is that?
Options:
A. 1.25 tablets
B. 1.5 tablets
C. 1.75 tablets
D. 2 tablets
Correct Answer: B. 1.5 tablets
Rationales:
Correct answer: 34×2=64=32=1.5\frac{3}{4} \times 2 =
\frac{6}{4} = \frac{3}{2} = 1.543×2=46=23=1.5 tablets. This is the
total per 2 doses.
A: 1.25 tablets reflects an incorrect fraction conversion.
C: 1.75 tablets overestimates the total.
D: 2 tablets is too high and results from rounding up incorrectly.
Teaching Point: Multiply the numerator by the whole number,
then simplify.

Stem: A child is prescribed 1/2 of a measured dose, and the
original dose equals 2/3 mL. How much medication should the
nurse prepare?
Options:
A. 1/6 mL
B. 1/3 mL
C. 2/3 mL
D. 1 mL
Correct Answer: B. 1/3 mL
Rationales:
Correct answer: 12×23=26=13\frac{1}{2} \times \frac{2}{3} =
\frac{2}{6} = \frac{1}{3}21×32=62=31 mL. The product of the
fractions gives the prepared volume.
A: 1/6 mL is the result of multiplying the wrong numerators or
denominators.
C: 2/3 mL ignores the ordered fraction reduction.
D: 1 mL is too large and unsafe.
Teaching Point: Multiply fractions straight across, then reduce.

Stem: The medication cup holds 3/4 tablet of a scored drug.
Each scored piece equals 1/4 tablet. How many pieces does the
nurse have?
Options:
A. 1 piece
