Which is an IO access method listed for trauma in the material?

• A. EZ-IO Humerus
• B. EZ-IO Tibia
• C. FAST1
• D. Seldinger technique

Answer: (B)

Intraosseous access is used in trauma to get rapid vascular access when IV lines are hard to obtain. The tibial insertion with the EZ-IO system is the IO method highlighted for trauma because it allows quick, reliable delivery of fluids and medications directly into the bone marrow space, bypassing collapsed veins and saving crucial seconds in resuscitation.

The tibia site is favored for its easy landmarks and straightforward placement, so you can soon administer life-saving therapy without delay. While the humerus IO option exists, the material in question lists the tibia as the IO access method for trauma. Other items listed, like a FAST exam device, are about assessment, not IO access, and the Seldinger technique refers to conventional venous catheter insertion, not intraosseous access.
