1) Arabic Numbers and Roman Numerals
Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Question:
The medication order reads digoxin IX mcg PO daily. The nurse
,must document the dose using Arabic numerals. How many
micrograms should be recorded?
A. 9 mcg
B. 11 mcg
C. 14 mcg
D. 19 mcg
Correct Answer: A. 9 mcg
Rationale — Correct:
IX = 9. The nurse should convert the Roman numeral correctly
before transcribing or administering the dose. Accurate numeral
interpretation prevents dose errors.
Rationale — Incorrect Options:
B is XI, not IX, and reflects reversing the numeral values.
C is XIV, which is a different Roman numeral.
D is XIX, which is also incorrect.
Teaching Point: Roman numerals must be read exactly as
written to avoid transcription errors.

,Question:
A provider writes the medication dose as XVI mg. The nurse is
preparing the dose and needs the Arabic numeral equivalent.
What dose should the nurse recognize?
A. 16 mg
B. 14 mg
C. 19 mg
D. 6 mg
Correct Answer: A. 16 mg

A. 1.5 mg
B. 1.0 mg
C. 2.5 mg

The tablets cancel, leaving milligrams. This is the correct dose to
administer.
Rationale — Incorrect Options:
B comes from rounding or multiplying incorrectly.
C is too high and reflects a calculation error.
D represents the full tablet amount, not 3/4 tablet.
Teaching Point: Multiply the fraction by the labeled amount,
then cancel units.
