Question

What is the rule of nines?

Answer 1

Rule of nines:

1. Sometimes, burns are assessed and expressed in words of the size of the total area that is affected.
2. This is called the rule of nines that links particular anatomical regions with a percentage that is a factor of none. Also, burns can be categorized by their degrees of severity:

• First-degree burn- affects the epidermis only.
• Second-degree burn- deeper, affecting the epidermis and some part of the dermis.
• Third-degree burn- extends fully into the epidermis and dermis. It destroys the tissue and affects the sensory functions and nerve endings.
• Fourth-degree burn- affecting underlying muscles and bones.
