To prevent errors, where should the "Tall Man" letters be applied in "hydrOXYzine"?
Answer choices

- CIn the middle
- DNowhere
About this question
Where should Tall Man letters appear in hydrOXYzine? Tall Man lettering capitalizes the dissimilar part of look-alike drug names so pharmacy staff can tell products apart during picking. On PTCB patient safety practice questions, the capitals mark the segment that differs — not a decorative style choice.
Knowing where Tall Man letters go is more than formatting trivia: it is an ISMP-endorsed error-prevention tool tested on CPhT exams. Use this item to lock the hydrOXYzine versus hydrALAZINE pattern, then compare it with other common Tall Man pairs until the visual cue feels automatic on exam day.

Correct answer
- AAt the end
- BAt the start
- CIn the middleCorrect
- DNowhere
Basic rationale
Tall Man lettering (hydrOXYzine vs hydrALAZINE) capitalizes the dissimilar parts of the name to prevent selection errors.
Option explanations
- A: Incorrect. The suffix '-ine' is common to many drugs and does not distinguish this LASA pair.
- B: Incorrect. Both drugs share the 'hydr-' prefix; capitalizing the start would not differentiate them.
- C: Correct. Tall Man letters capitalize the dissimilar middle portion (OXY vs ALA) to distinguish the drugs.
- D: Incorrect. Tall Man lettering is a required safety strategy for this look-alike drug pair.
Deep Analysis
Core logic
Tall Man lettering is a safety strategy that capitalizes the dissimilar portions of look-alike drug names to help distinguish them. hydrOXYzine (antihistamine) vs hydrALAZINE (antihypertensive) share the prefix 'hydr-' and suffix '-ine', so the unique middle portions (OXY vs ALA) are capitalized to draw the eye to the difference.
Distractor analysis
A: The suffix '-ine' is common to many drugs (morphine, codeine, etc.) and does not distinguish this pair. B: The prefix 'hydr-' is shared by both hydrOXYzine and hydrALAZINE, so capitalizing the start would not help. D: Tall Man lettering is specifically required for this LASA pair; saying 'nowhere' ignores the safety protocol.
Exam trap
Tall Man letters go on the parts that are DIFFERENT, not the parts that are the same. Find what's unique in the middle of the name.
Memory tip
🔤 Tall Man = 'Target the Difference'. Capitalize the letters in the MIDDLE where the names DIFFER.
