Which list represents drugs that can be administered via an endotracheal tube (ETT) using the LEAN mnemonic?

• A. Lidocaine, Epinephrine, Atropine, Narcan
• B. Morphine, Epinephrine, Ativan, Narcan
• C. Lidocaine, Epinephrine, Albuterol, Narcan
• D. Lidocaine, Epinephrine, Atropine, Dextrose

Answer: (A)

The idea being tested is which drugs are safely administered through an endotracheal tube using the LEAN mnemonic. LEAN stands for Lidocaine, Epinephrine, Atropine, and Naloxone (Narcan). These four drugs are taught for endotracheal administration because they have relatively reliable absorption through the tracheal mucosa and can produce rapid systemic effects when IV access isn’t available.

Therefore, the list that matches LEAN is Lidocaine, Epinephrine, Atropine, and Naloxone. Dextrose, morphine, benzodiazepines like lorazepam, and albuterol don’t belong to this mnemonic and aren’t standard ET tube medications in this context due to inconsistent absorption or safer alternatives via other routes.
