🔍 Key Concepts

• Priorities in first aid: what you do immediately after a major injury to preserve life until advanced care arrives • Traumatic shock: how the body reacts to serious injury and blood loss • Difference between treating the visible wound and treating the whole patient’s condition

💭 Think About

• After you stop the bleeding or splint the injury, what life‑threatening condition might still be silently developing? • Which option is a general treatment step that could apply to almost any serious injury, not just special cases? • On a vessel far from shore, what systemic body reaction must you anticipate whenever there is a major injury?

✅ Before You Answer

• Identify which choice is not always appropriate for every major injury (think about when CPR, oxygen, or removing objects could be harmful or unnecessary). • Recall the basic first aid rule: do not remove embedded objects in a wound unless trained and required to do so. • Verify which option is specifically associated with supporting circulation and preventing collapse of the body’s vital functions after severe injury.
