During a medical emergency, which is an important action to take if the victim is conscious?

Asking questions about the victim's medical history is essential during a medical emergency when they are conscious. This action allows you to gather important information that can aid in their treatment and care, providing rescuers and medical professionals with critical insights into any pre-existing conditions, allergies, medications, or other relevant health issues. Understanding the victim's medical background helps to guide the care you provide until help arrives.

In contrast to this approach, starting CPR is reserved for situations where the victim is unresponsive and not breathing. A physical examination, while important, may not yield immediate critical information as effectively as obtaining a medical history. Finally, waiting for a professional to arrive without gathering vital information can delay necessary care that could improve the victim's outcome.
