The key answer of exercise 1

First aid refers to the immediate assistance or care provided to someone who has been injured or suddenly taken ill before professional medical help arrives. The primary aim of first aid is to preserve life, prevent the condition from worsening, and promote recovery. It includes simple techniques and procedures that can be performed with basic supplies and equipment, such as bandages, antiseptics, and CPR (cardiopulmonary resuscitation). First aid skills are valuable in various situations, including accidents, sudden illnesses, and emergencies, and they can make a significant difference in the outcome for the person in need of help.
