Correct Answer » A Explanation |
 |
Intraosseous infusion (IO) is the process of injecting medications, fluids, or blood products directly into the marrow of a bone; this provides a non-collapsible entry point into the systemic venous system.
Clinical Reasoning for the Correct Answer
– Intraosseous cannulation is primarily performed to provide rapid vascular access during emergencies when peripheral venous access is difficult or impossible.
– The image shows a specialized needle inserted into the proximal tibia’s metaphyseal region, typical for IO fluid and medication administration.
– Fluid therapy (resuscitation fluids, medications) can be administered via IO access rapidly and effectively.
– Indications for Intraosseous Cannulation
– Emergent vascular access when peripheral veins are inaccessible
– Pediatric emergencies, shock, cardiac arrest
– Administration of fluids, blood products, and medications
