A client received burns to his entire back and left arm. using the rule of nines, the nurse can calculate that he has sustained burns on 27 per cent of his body.
In pre-hospital and emergency medicine, the Wallace rule of nines is a method used to calculate the total body surface area (BSA) impacted by a burn.
The "rule of nines" can be used to rapidly determine the size of a burn. The surface area of the body is divided using this method into percentages. 9% of the surface area of the body is made up of the front and back of the head and neck. Each arm and hand's front and back together make up 9% of the body's surface area.
Second-degree burns, commonly referred to as partial-thickness burns, are the intended application of the rule of nines. full-thickness burns are also referred to as third-degree burns.
