Which term means pertaining to within the trachea?

• A. Intratracheal
• B. Endotracheal
• C. Transtracheal
• D. Peritracheal

Answer: (B)

The idea being tested is how prefixes describe location relative to an organ. Endo- means inside or within, and when attached to tracheal it gives endotracheal—the term used for something located inside the trachea, such as an endotracheal tube placed within the tracheal lumen to secure the airway. The other forms don’t convey the exact sense of inside the trachea: intratracheal isn’t a common clinical term for inside the trachea, transtracheal would mean across or through the trachea, and peritracheal means around the trachea.
