Which of the following should never be done when providing first aid?

When providing first aid, encouraging the victim to move can potentially worsen their condition, especially if they have sustained a serious injury, such as a spinal injury or fractures. Movement can lead to further injury or complications, so it's crucial to keep the victim as still and comfortable as possible until professional help arrives. Proper first aid entails assessing the situation and ensuring the safety of the victim, which often involves not moving them.

On the other hand, comforting the victim is essential as it can help reduce anxiety and fear, creating a more positive environment during a stressful time. Calling for help is a critical step in first aid to ensure that professional medical assistance is on the way. Using appropriate equipment is also vital as it can aid in stabilizing the victim and providing the necessary care without causing further injury.
