Intraosseous access is not indicated for which casualty condition?

• A. Dehydration casualty after two unsuccessful IV attempts
• B. Apnea with rapid IV access
• C. Pediatric shock
• D. Adult with good IV access

Answer: (A)

Intraosseous access is a rapid alternative vascular route used when IV access cannot be obtained quickly or is likely to be delayed, such as in children, shock, or after multiple failed IV attempts. If IV access is already reliable and fast, there’s no need to resort to IO. That makes the scenario of an adult with good IV access not a situation that requires IO. The other scenarios describe situations where IV access is difficult or unavailable (as with dehydration after failed IV attempts) or where IO is commonly used to support urgent resuscitation (pediatric shock).
