   Show Answer & Explanation

   Correct Answer
   B. To highlight the differences between look-alike drug names and reduce errors

   Correct — Tall-man lettering is a naming convention recommended by the FDA and ISMP to differentiate between look-alike drug names (LASA) by emphasizing the dissimilar letters in each name. This visual cue helps reduce medication errors caused by name confusion. It does not indicate pronunciation, brand vs. generic status, or controlled substance scheduling. Examples include hydrOXYzine vs. hydrALAZINE and vinBLAStine vs. vinCRIStine.
