This is an exam question from the Traffic Rules of Ukraine (PDR) concerning safety after a traffic accident and basic first aid skills that may be required of a driver before the arrival of medical professionals. In real road situations, burns can occur due to fire, hot liquids, steam, or contact with heated elements, so knowing the correct actions helps reduce the risk of complications and avoid causing further harm to the victim.
The question checks the understanding of the driver's duties under Section 2 "Duties and Rights of Drivers," specifically item 2.10 (sub-item "g") of the traffic rules: to take possible measures to provide first aid and call an ambulance. The key idea is this: if burn blisters are accidentally damaged, the surface becomes an open wound, so as part of first aid, it must be protected from infection and further injury by covering it with a clean, sterile, dry gauze bandage without applying pressure to the tissues.
Analysis of the options in the logic of the theoretical exam: applying a sterile dry bandage is correct because it isolates the injured area and does not irritate it with unnecessary actions. Prolonged cooling with water may be appropriate at the early stage of a fresh burn, but when blisters are already damaged, the priority is to cover the wound and prevent infection, not to continue rinsing. Treating the burn surface, especially an open one, with disinfectants is not a safe action for a non-professional: such substances can worsen tissue damage and pain, so the first aid rules in the PDR of Ukraine emphasize a sterile dry covering and calling medical professionals.
Clause 2.10 (subclause “g” of section 2 “Duties and Rights of Drivers”)
In the event of involvement in a road traffic accident, the driver is obliged to: d) take possible measures to provide pre-medical assistance to the victims, and call an emergency (ambulance) medical team.
Application: this exam question checks whether the driver, within the scope of “pre-medical assistance”, can perform the correct action when burn blisters are damaged — to cover the wound with a sterile dry dressing, without causing additional tissue injury and reducing the risk of infection.
Clause 1.10 (term “Road Traffic Accident”)
Road traffic accident — 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.
Application: the context of providing pre-medical assistance in the Traffic Rules is specifically tied to the case of a road traffic accident, within which the driver must fulfill the duties defined in clause 2.10.
That is, the correct answer is “Apply a clean, sterile dry gauze dressing to the burn site, which does not put pressure on the soft tissues.”, 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 covering the damaged burn surface with a sterile dry dressing is an appropriate pre-medical measure to reduce the risk of infection and additional trauma.
During a thermal burn, blisters serve as a natural protection: they cover the damaged tissues from dirt and microbes. Therefore, in first aid, the rule is not to interfere with unnecessary manipulations in the burn area and not to attempt to "treat" it aggressively.
If, during the provision of aid, the blisters are accidentally damaged, the burn surface essentially becomes an open wound. In this situation, the main task of the driver providing first aid is to minimize the risk of infection and further injury to the skin as much as possible.
The safest step within the scope of first aid is to cover the burn area with a clean, sterile material. The dressing should be dry and applied in such a way that it only covers the area, without compressing the tissues: pressure can increase pain, damage the vulnerable surface, and worsen the injury.
For example, if after a traffic accident the victim has a burn from hot liquid, and during covering or moving the person the blister bursts, the correct action is to immediately cover the area with a sterile dry gauze and secure it without tension, avoiding any "cauterizing," puncturing, or applying foreign substances.
Thus, the correct answer is "Apply a clean, sterile, dry gauze dressing to the burn area that does not put pressure on the soft tissues," because after the blisters are damaged, the burn becomes an open wound and requires protection from infection and further injury without unnecessary pressure on the tissues.
