What is the definition of first aid?

The definition of first aid refers to the initial assistance or treatment given to someone suffering from a minor or serious medical condition or injury, typically before professional medical help arrives. This care aims to preserve life, prevent the condition from worsening, and promote recovery. The focus is on providing immediate support and addressing the most urgent needs of the casualty until trained medical personnel can take over.

In this context, choosing the option that describes first aid as the first care given to casualties before other medical personnel can provide treatment accurately reflects the crucial role of first aid in emergency situations. It emphasizes the timely intervention that can make a significant difference in the outcomes of injuries or medical emergencies. Other options do not capture the comprehensive role of first aid, which extends beyond temporary fixes or specific pain-relief methods.
