Question: A provider writes a medication schedule as every VI
hours. The nurse is preparing the MAR for a 24-hour period.
How many doses will the patient receive in 1 day?
Options:
A. 3 doses
,B. 4 doses
C. 6 doses
D. 8 doses
Correct Answer: B
Rationale — Correct Answer: VI = 6 hours. Use 24 ÷ 6 = 4 doses
in 24 hours. This is a safe scheduling check because the nurse
must confirm the interval before administration.
Rationale — Incorrect Options:
A. 3 doses reflects dividing by 8 instead of 6.
C. 6 doses comes from confusing hours with dose count.
D. 8 doses would require q3h, not q6h.
Teaching Point: Convert Roman numerals before calculating
medication frequency.
