This is an exam question from the Traffic Rules of Ukraine concerning first aid at the scene of a traffic accident and is directly related to road safety: in real-life situations, a driver or witness to an accident may find themselves next to a casualty who is rapidly losing blood. Massive external bleeding from a limb is a critical condition where every second counts, so the traffic rules require you not to panic, but to act as simply and effectively as possible until medical professionals arrive.
This question tests the section of the Traffic Rules regarding the driver's duties in the event of involvement in a traffic accident, specifically item 2.10 (subitem "e") concerning taking possible measures to provide first aid. In the context of the theoretical exam, it is important to understand the basic algorithm: the primary action in the case of severe bleeding is to mechanically reduce blood loss by applying direct pressure to the wound, and then securing this pressure with a pressure bandage to maintain the effect and allow for other steps (calling for help, monitoring the condition).
The analysis of the answer options in this exam question is straightforward: the option involving firm pressure on the wound and applying a pressure bandage corresponds to the principle of "stop the bleeding first" and provides the fastest result in the case of massive bleeding. On the other hand, rinsing with water is not a priority in the first moments, as it does not stop active blood loss and can lead to a loss of precious time; cleaning the wound is only performed after the bleeding is controlled or by medical professionals. This knowledge directly helps to successfully pass the theoretical exam and, most importantly, to act correctly in a real-life situation on the road.
Clause 2.10 (driver's duties in case of involvement in a road traffic accident, subclause "e")
"...take possible measures to provide pre-medical assistance to the victims, call (if necessary) emergency medical services..."
This clause of the Traffic Rules checks the driver's duty to ensure the provision of pre-medical assistance to the victims; the specific action "press as firmly as possible on the wound and apply a pressure bandage" is the basic method of temporarily stopping massive external bleeding within the scope of pre-medical assistance.
Clause 1.10 (the term "Road Traffic Accident")
"A road traffic accident is an event that occurred during the movement of a vehicle, as a result of which people were killed or injured or material damage was caused."
This term in the Traffic Rules sets the context in which the obligation from clause 2.10 arises (specifically regarding victims/injured persons).
Thus, the correct answer is "Press as firmly as possible on the wound with your hands and apply a pressure bandage," given that according to the definition in the Traffic Rules, in the event of a road traffic accident, the driver is obliged to take possible measures to provide pre-medical assistance to the victims, and the primary pre-medical action in case of massive external bleeding from a limb is direct pressure on the wound and application of a pressure bandage to temporarily stop it.
When you see the source of massive external bleeding from a wound on a limb, the main danger is very rapid blood loss. In such a situation, the first seconds are crucial: if you do not reduce the bleeding immediately, the victim's condition may deteriorate sharply even before the arrival of medical personnel.
The very first action should be direct, strong pressure on the bleeding site. This is the fastest way to mechanically "block" the exit of blood from the damaged vessels. You press the wound with your hands (if possible, through a clean napkin, bandage, or cloth) and do not ease the pressure while you prepare or apply a dressing. For example, if blood is "spurting" from a cut on the forearm, you immediately press the wound with your palm and only after that secure the pressure with a bandage or piece of cloth so that it continues to compress the wound.
The next logical step, performed immediately after pressing, is to apply a pressure dressing. It is needed so that pressure on the wound is maintained constantly without the involvement of your hands. This allows you to stabilize the bleeding and move on to other necessary actions (calling for help, monitoring the victim's condition) without losing the effect of stopping the blood.
Other techniques, such as changing the position of the limb or applying a tourniquet, are not primary according to the wording of the question, because they do not provide such an immediate result as direct pressure on the wound. A tourniquet is generally used when bleeding cannot be stopped by pressure and a pressure dressing, or when circumstances do not allow you to maintain reliable pressure.
Therefore, the correct answer is "Press as hard as possible on the wound with your hands and apply a pressure dressing," because it is direct pressure and a pressure dressing that most quickly reduce massive bleeding and prevent critical blood loss.
