What is the damage after the thermal effect of current on living tissue?

• nerve injuries

• burns

• vascular traumas

• all of the mentioned

What does protective grounding provide in rooms with electrical installations?

• Reducing touch voltage to a safe level

• Creating dangerous conditions for people

• Voltage boost for safe operation

• Increasing the touch current

What is the scientific rationale behind not burying a person who has received an electric shock?

• Contact with open skin wounds can cause severe tissue damage.

• It may alter the electrical potential of the ground.

• Burying can lead to the formation of an electric field around the victim.

• It helps with reducing the toxicity of the received shock

What should be the first action taken in the event of an electric shock?

• Checking the victim's pulse.

• Applying first aid immediately.

• Turning off the main power source.

• Disconnecting any nearby electrical connections to the affected equipment.

To separate the victim from live parts or wires, you can use:

• metal objects

• wet objects

• dry clothes

• none of the mentioned

What is the recommended ratio of chest compressions to rescue breaths in cardiopulmonary resuscitation (CPR) for adults?

• 15 compressions to 2 rescue breaths

• 30 compressions to 2 rescue breaths

• 30 compressions to 1 rescue breath

• 10 compressions to 1 rescue breath

What is the recommended depth for chest compressions during hands-only CPR for adults?

• 5 centimeters

• 2.5 centimeters

• 7.5 centimeters

• 10 centimeters

In what situations would one perform hands-only cardiopulmonary resuscitation (CPR)?

• When the victim is conscious but experiencing chest pain

• When the victim has a visible injury on their chest

• When the victim is unresponsive and not breathing normally

• When the victim is unconscious but breathing normally

Which material is commonly used as protection against gamma radiation in nuclear facilities?

• Aluminum

• Copper

• Lead

• Steel

What are the recommended steps to take when assisting an unconscious individual?

• Lay them down in an uncomfortable position, tightly secure their clothing, and avoid providing fresh air.

• Keep them standing upright, tighten their clothing, and ensure a crowded environment.

• Lay them down comfortably, loosen and unbutton their clothing, provide fresh air flow, and remove unnecessary bystanders.

• Sit them up straight, loosen and unbutton their clothing, and restrict air flow to prevent overheating.
