Which of the following is primarily used to assess burn size in patients?

The Rule of Nines is primarily used to assess burn size in patients because it provides a quick and standardized method to estimate the total body surface area (TBSA) affected by burns. This method divides the body into sections, each representing approximately 9% (or a multiple of 9%) of the total body surface area. For example, the head and neck are considered 9%, each arm is 9%, and each leg is 18%. This rapid assessment is crucial in guiding treatment decisions, fluid resuscitation needs, and determining the severity of burns, which can significantly impact patient management.

The other options serve different purposes and are not primarily focused on assessing burn size. The Glasgow Coma Scale evaluates a patient’s level of consciousness and neurological function, while the Apgar Score measures the health of newborns immediately after birth based on various clinical factors. A Body Surface Area Calculator would provide a more detailed assessment of body surface area but is not as widely utilized for the quick estimation of burn size as the Rule of Nines.
