Which medications can be administered via an ET tube?

The correct response highlights medications that are effective when administered through an endotracheal (ET) tube. Lidocaine, epinephrine, atropine, and Narcan are all medications that can be delivered via this route and are particularly relevant in emergency situations, such as cardiac arrest or severe respiratory distress.

Lidocaine can be used for its antiarrhythmic properties, epinephrine for its vasoconstrictive effects during resuscitation, atropine to manage bradycardia, and Narcan for opioid overdose reversal. Administering these medications through an ET tube is useful when intravenous access is not readily available and rapid action is necessary.

In contrast, the other groups of medications listed do not possess the same efficacy when given through an ET tube. Aspirin, ibuprofen, and acetaminophen, for instance, are non-opioid analgesics and anti-inflammatory drugs that are typically administered orally or intravenously, not via ET. Similarly, fentanyl and diazepam need precise dosing that intravenous delivery provides, while dobutamine and adenosine are specific to IV administration due to their rapid action and need for immediate effects. Finally, insulin, nitroglycerin, metoprolol, and dexam
