Question:
A nurse reviews a legacy chart written in Roman numerals. The
provider’s note lists a medication dose of IX mg. What is the
dose in Arabic numerals?
,Options:
A. 8 mg
B. 9 mg
C. 10 mg
D. 11 mg
Correct Answer: B. 9 mg
Rationales:
• Correct (B): IX equals 9 because I before X subtracts 1 from
10. The dose is 9 mg.
• A: VIII equals 8, which is a common misread of IX.
• C: X equals 10, but IX is one less than 10.
• D: 11 is XI, not IX.
Teaching Point: Roman numerals use subtraction when a
smaller numeral comes before a larger one.

Question:
A nurse sees a medication supply count written as XIV tablets in
a drawer. How many tablets is that?
,Options:
A. 11 tablets
B. 13 tablets
C. 14 tablets
D. 16 tablets
Correct Answer: C. 14 tablets
Rationales:
• Correct (C): XIV equals 10 + 4, which is 14.
• A: XI is 11, not XIV.
• B: XIII is 13; the IV changes the value.
• D: XVI is 16, which is different from XIV.
Teaching Point: Roman numerals must be read from left to right
with subtraction rules in mind.

Question:
A nurse prepares a dose that is 3/4 of a tablet. The tablet
strength allows this portion to be administered safely. What
fraction of one tablet is being given?
, Options:
A. 1/5 tablet
B. 3/10 tablet
C. 2/5 tablet
D. 3/4 tablet
Correct Answer: B. 3/10 tablet
Rationales:
• Correct (B): 34×25=620=310\frac{3}{4} \times \frac{2}{5} =
\frac{6}{20} = \frac{3}{10}43×52=206=103. Multiply
numerators and denominators, then simplify.
• A: 1/5 is too small and does not match the multiplication
result.
• C: 2/5 is 0.4, which is larger than 3/10.
• D: 3/4 is the starting fraction, not the product.
Teaching Point: Multiply fractions straight across, then simplify
before comparing answers.
