Question:
A provider orders levothyroxine tab ii PO daily. Each tablet
contains 25 mcg. How many micrograms will the patient receive
per dose? The nurse must convert the Roman numeral correctly
before calculating the total dose.
,Options:
A. 25 mcg
B. 50 mcg
C. 75 mcg
D. 100 mcg
Correct Answer: B. 50 mcg
Rationales:
Correct: Roman numeral ii = 2. Calculate 2 tablets × 25
mcg/tablet = 50 mcg. The tablet unit cancels, leaving
micrograms.
A: This reflects only one tablet and ignores the Roman numeral.
C: This adds an extra tablet and overestimates the ordered
dose.
D: This doubles the correct dose and is unsafe.
Teaching Point: Convert Roman numerals to Arabic numbers
before doing the dose calculation.

Reference: Ch. 1 — Arabic Numbers and Roman Numerals
Question:
A medication order reads tab IV PO daily. Each tablet contains
12.5 mg. How many milligrams will the patient receive in one
,dose? The nurse should interpret the Roman numeral correctly
to avoid an underdose or overdose.
Options:
A. 12.5 mg
B. 25 mg
C. 50 mg
D. 100 mg
Correct Answer: C. 50 mg
Rationales:
Correct: Roman numeral IV = 4. Calculate 4 tablets × 12.5
mg/tablet = 50 mg.
A: This reflects one tablet instead of four.
B: This equals two tablets, not four.
D: This is twice the correct total and is not the ordered dose.
Teaching Point: Roman numeral errors can cause major
medication errors.

3) Multiplying Fractions
Reference: Ch. 1 — Fractions — Multiplying Fractions
Question:
A patient takes 3/4 of a 20-mg tablet twice daily. What is the
, total daily dose in milligrams? The nurse needs to calculate the
amount from the fraction of a tablet and the number of doses.
Options:
A. 15 mg
B. 30 mg
C. 35 mg
D. 40 mg
Correct Answer: B. 30 mg
Rationales:
Correct: Calculate 20 mg × 3/4 × 2 = 30 mg. The fraction of the
tablet is applied first, then multiplied by the number of doses.
A: This represents only one half of the daily amount.
C: This is a common overestimate from incorrect multiplication.
D: This equals a full tablet twice daily, not 3/4 tablet.
Teaching Point: Multiply fractions carefully before rounding or
converting units.
