How many attempts are allowed per extremity for intraosseous access?

How many attempts are allowed per extremity for intraosseous access?

• A. Two
• B. Three
• C. One
• D. Zero

Answer: (C)

The main idea is safety and efficiency in IO access. In this protocol, you’re allowed one attempt on each extremity. The reason is to minimize tissue trauma and potential complications from multiple penetrations while still prioritizing rapid access in emergencies. If that single attempt on a limb doesn’t establish a reliable IO access, move to a different site on another limb or switch to an alternative access method as directed by protocol. This approach helps you quickly obtain vascular access without repeatedly injuring the same bone or surrounding tissue.
