What should you never give an injured person at the scene of a crash?

When tending to an injured person at the scene of a crash, it is crucial to avoid giving them anything to drink, including water. This is essential because, in some cases, the individual may require surgery or medical intervention that requires an empty stomach; if they have ingested food or drink, it could complicate or contraindicate those procedures. Additionally, if the person is unconscious or semi-conscious, there is a risk of choking if they swallow something while in that state. Therefore, keeping them hydrated is not only unnecessary but can be potentially harmful.

The other actions mentioned, like administering CPR or providing a bandage, are scenarios where immediate care may be required depending on the injuries present. Offering comforting words can help provide emotional support, which is also beneficial in a crisis situation.
