Florida State Paramedic Practice Exam

In the Rule of Nines, which is a method used to estimate the total body surface area (TBSA) affected by burns, the chest and abdomen in infants account for a larger percentage compared to older children and adults due to their proportionally larger heads and smaller limbs. In infants, the chest and abdomen combined represent approximately 18% of the body surface area. This adjustment reflects the differing anatomical proportions of infants, which is an important consideration in pediatric burn assessments and treatment protocols. Understanding the Rule of Nines is crucial for paramedics and emergency responders when evaluating burn injuries and calculating fluid resuscitation needs.
