In the pediatric Rule of Nines, what percentage is allocated to the anterior head?

Explanation:
The concept tested is how the pediatric Rule of Nines allocates body surface area for the head. In children, the head accounts for 18% of TBSA, and this is split roughly equally between the front (anterior) and back (posterior) surfaces. Half of 18% is 9%, so the anterior head is 9% of TBSA. (For contrast, adults treat the head as 9% total, so the front would be about 4.5% if split.)
