Which finding would most strongly suggest incorrect intraosseous placement during rapid access?

• A. It wiggles
• B. It bleeds constantly
• C. It makes a loud beep
• D. It heats up instantly

Answer: (A)

The main idea here is that rapid intraosseous access requires the needle to be firmly anchored in the bone so medications and fluids flow reliably into the medullary space. If the needle wobbles, that strongly suggests it isn’t properly seated in the marrow cavity—perhaps it’s in soft tissue or has slipped out of position. Movement means poor seal, unreliable drug delivery, and a higher risk of extravasation, so the safest course is to stop, reassess the placement, and reinsert or reposition at the same or a different site as needed.

Bleeding that continues constantly can occur with tissue trauma during entry and isn’t a definitive sign of misplacement. A loud beep or a sensation of heat isn’t an indicator of where the needle sits inside the bone and doesn’t point to incorrect placement.
