Which of the following has been implemented by the FDA to eliminate medication errors?

Sound-alike, look-alike names
"Tall man" letters
Do NOT crush list
All of the above

"Tall man" letters

Rationale: The FDA has implemented "tall man" letters to distinguish similarly spelled medications by capitalizing differences between drug names. Sound-alike, look-alike names lists and the "do NOT crush list" were created by the Institute of Safe Medication Practices. All of these are tools that assist in reducing medication errors.
