What is a key step to take when contacting medical professionals after an incident?

Completing an incident report is crucial when contacting medical professionals after an incident because it provides a comprehensive account of what occurred. This documentation includes vital information such as the timeline of events, the identities of those involved, and specific details regarding the nature of the incident and any observed symptoms. Having a completed incident report helps medical professionals assess the situation more effectively, enabling them to offer appropriate advice and treatment if needed.

The other options do not prioritize the importance of accurate documentation, which enhances the communication process with medical personnel. Leaving the scene could compromise care and support for those in need, while waiting for symptoms to improve may delay necessary assistance. Contacting friends or family without first ensuring proper medical support can lead to miscommunication and may not prioritize the immediate medical needs of those affected.
