Access to evacuation routes is essential at a casualty collection point because it provides the clear, coordinated paths needed to move wounded beyond the CCP to higher medical care. These routes allow the team to use the fastest and safest transport available—whether ground vehicles, litter bearers, or evac helicopters—without causing bottlenecks or delays. Routes must be mapped, unobstructed, and synchronized with evacuation assets so that triage, initial care, and transport flow smoothly together. Without defined routes, casualties can back up at the CCP and vital care is delayed. While different terrains may require air, ground, or mixed movement, having reliable evacuation routes ensures flexibility and efficiency in getting patients to the next level of treatment.

The main idea is identifying contraindications to tranexamic acid. A known allergy to tranexamic acid is an absolute contraindication because giving it to someone who is allergic could trigger a dangerous hypersensitivity reaction. Hypertension and diabetes by themselves don’t prevent TXA use, and recent aspirin use isn’t an absolute contraindication either—though bleeding risk must still be considered and managed as part of the overall clinical picture. The key takeaway is that an allergy to TXA means you should not administer it.

Antibiotics are used in field care to prevent infection in wounds that are open and contaminated. When the skin is broken and the wound is exposed to dirt, debris, or battlefield contaminants, bacteria can enter quickly and multiply. Starting antibiotics for open combat wounds helps reduce the risk of infection and complications from contamination. Closed wounds have intact skin, so the natural barrier reduces infection risk; antibiotics are not routinely given unless signs of infection appear or there are specific risk factors. Infected wounds do require antibiotic treatment, but the field standard aims to prevent this scenario by treating open wounds early. Therefore, open combat wounds are the situation where antibiotics are indicated.

The recovery position is used for an unconscious casualty who is breathing and does not have signs of shock, to keep the airway open and reduce the risk of aspiration. When a person is unconscious, the tongue can relax back and partially block the airway; lying them on their side with the head supported helps prevent that, and allows any secretions or vomit to drain away from the airway. It also stabilizes the person so you can monitor breathing and consciousness while help is on the way. If the casualty were in shock, the focus would be on supporting circulation and treating the shock first, and turning them for a side-lying recovery position might not be appropriate as a standing priority. A conscious person who is actively vomiting should be placed on their side to drain, but they are not in the unconscious recovery-position scenario. A conscious casualty who requires immediate airway management needs airway procedures rather than simply being placed in the recovery position.
