Which basic first-aid step should be taken for a minor cut?

For a minor cut, the appropriate first-aid step involves cleaning the wound properly to reduce the risk of infection, applying antiseptic to kill any remaining bacteria, and then covering it with a sterile bandage to protect it from dirt and further injury. This method not only promotes healing but also ensures that the cut is safeguarded against germs.

Applying a tourniquet is not suitable for a minor cut, as it's typically reserved for severe bleeding and can cause unnecessary harm if used incorrectly. Rinsing with cold water only does not cover the critical step of using soap to thoroughly clean the area, which is essential in preventing infection. Leaving the cut uncovered for air exposure can lead to increased risk of contamination, as it does not provide adequate protection to the wound. Overall, cleaning, applying antiseptic, and covering with a sterile bandage is a comprehensive approach that addresses both cleanliness and protection.
