Final answer:
The drugs listed (methotrexate, fluorouracil, hydroxyurea, mercaptopurine, and thioguanine) are chemotherapy agents, not typically given via ET tube. Medications that can be administered through an ET tube include Lidocaine, Epinephrine, Atropine, and Naloxone following the 'LEAN' mnemonic.
Step-by-step explanation:
Endotracheal (ET) Tube Drug Administration
While the drugs listed: methotrexate (Abitrexate®), fluorouracil (Adrucil®), hydroxyurea (Hydrea®), mercaptopurine (Purinethol®), and thioguanine are indeed important chemotherapy agents, they are not typically administered via an endotracheal (ET) tube. ET tube medication administration is often used in emergency scenarios, and the medications approved for this route are limited and must follow the mnemonic 'LEAN' for:
- Lidocaine
- Epinephrine
- Atropine
- Naloxone
These medications are chosen for their ability to be absorbed through the tracheal lining quickly. In addition, medications given via ET tube must be given in higher doses than those given intravenously due to lower absorption rates.
