Correct answer
C. haemorrhage.
Explanation
A pressure (compression) dressing is applied in the case of heavy bleeding (haemorrhage) - answer C. With a crushed limb (A), pressing on the injured place may make the injuries worse, and bloody fluid leaking from the ear (B) is a sign of a skull injury and must not be stopped - you cover the ear loosely, and an unconscious casualty who is breathing is placed lying on that side.
A pressure dressing is several layers of sterile gauze put on the wound and firmly bandaged; the pressure closes the blood vessels and stops the bleeding, and at the same time it does not cut off the blood supply to the whole limb like a tourniquet. When the dressing soaks through, you add more layers without removing the previous ones. Giving help in such a situation is the duty of every witness.
