Tall-man lettering is used to distinguish look-alike drug names by which of the following?

• A. Used to decorate packaging.
• B. Tall-man lettering is used to distinguish look-alike drug names.
• C. To encode patient data.
• D. To indicate expiry date.

Answer: (B)

Tall-man lettering is a safety technique used to reduce medication errors caused by look-alike drug names. By capitalizing the differing parts of similar names, it makes the distinct letters stand out visually, helping clinicians read orders, labels, and documentation more accurately in fast-paced or stressful situations. This practice aims to prevent wrong-drug or wrong-dose administration, not to decorate packaging, encode patient data, or indicate expiry dates. So the idea that tall-man lettering is used to distinguish look-alike drug names best captures its purpose and use in practice, making it the correct understanding.
