Question: 1 / 425

According to the Rule of Nines, how much of the body's surface area does the head and neck account for?

9%

The Rule of Nines is a system used to estimate the total body surface area (TBSA) affected by burns, which simplifies the process by dividing the body into sections that each represent approximately 9% of total body surface area. According to this rule, the head and neck collectively account for 9% of the total body surface area. This estimation is important in clinical settings to assess the severity of burns and to inform treatment decisions, including fluid resuscitation and transfer to specialized burn units.

In this context, the choice indicating that the head and neck account for 9% is therefore accurate and reflects the commonly accepted proportions within the Rule of Nines.
