What does "first aid" primarily include?

The definition of "first aid" primarily encompasses the immediate care provided to someone who is injured or suddenly becomes ill. This intervention is crucial as it aims to stabilize the patient's condition and prevent further harm until professional medical services can take over. First aid procedures are designed to be simple, effective, and accessible, allowing even those without extensive medical training to provide essential assistance in emergencies. Recognizing the critical role of timely care can significantly impact the outcome for an individual facing a medical crisis.

The other options describe concepts that fall outside the primary definition of first aid. Long-term rehabilitation techniques focus on recovery from chronic conditions rather than immediate intervention. Advanced medical procedures are generally reserved for trained medical professionals and not part of basic first aid. Routine health check-ups and prevention are proactive measures aimed at maintaining health, whereas first aid is a reactive response to emergencies. This differentiation highlights the specific and immediate nature of first aid in emergency situations.
