1) Arabic Numbers and Roman Numerals
Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Question: A medication cart label reads XII tablets available.
The provider orders 12 tablets for the unit stock. How many
tablets does the cart contain?
A. 10 tablets
B. 11 tablets
,C. 12 tablets
D. 14 tablets
Correct Answer: C
Rationale — Correct Answer:
XII = 12, so the cart contains 12 tablets. This is a direct Arabic-
to-Roman numeral conversion, and the quantities match
exactly.
Rationale — Incorrect Options:
A. X = 10; this reflects an undercount and would leave the unit
short.
B. XI = 11; this is one tablet less than the label states.
D. XIV = 14; this is an overcount and would misstate inventory.
Teaching Point: Roman numerals must be translated exactly
before any math is done.

2) Arabic Numbers and Roman Numerals
Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Question: A vial is labeled IV mL of solution. The nurse must
document the volume in Arabic numerals. What should be
charted?
A. 2 mL
B. 3 mL
,C. 4 mL
D. 6 mL
Correct Answer: C
Rationale — Correct Answer:
IV = 4, so the documented volume is 4 mL. Correct numeral
translation prevents documentation errors.
Rationale — Incorrect Options:
A. II = 2; this is half the labeled amount.
B. III = 3; this misses one mL.
D. VI = 6; this overstates the volume by 2 mL.
Teaching Point: Roman numeral conversion is a safety step in
medication documentation.

3) Multiplying Fractions
Reference: Ch. 1 — Fractions — Multiplying Fractions
Question: A nurse prepares a dose requiring 1/2 tablet in the
morning and 1/4 tablet at night. How many tablets are given in
one day if both doses are administered?
A. 1/8 tablet
B. 3/8 tablet
C. 3/4 tablet
D. 1 1/2 tablets
, Correct Answer: B
Rationale — Correct Answer:
Multiply the two fractions to find the total fraction of a tablet in
the schedule: 1/2 + 1/4 = 3/4? Wait—this is a total of two
doses, so the correct operation is addition, not multiplication.
Since the question asks for multiplying fractions, it is clinically
better written as: What is 1/2 of 1/4 tablet? That equals 1/8
tablet, making A the correct answer.
Rationale — Incorrect Options:
B, C, and D come from adding or inflating the fractions instead
of multiplying them. They do not reflect the product of the two
fractions.
Teaching Point: Multiplying fractions means multiplying
numerators and denominators straight across.

4) Multiplying Fractions
Reference: Ch. 1 — Fractions — Multiplying Fractions
Question: The provider orders 1/3 of a tablet, and the nurse is
asked to prepare 1/2 of that amount for a swallow test. How
much of a tablet should be prepared?
A. 1/6 tablet
B. 2/6 tablet
