Which of these is part of the pediatric assessment triangle?

• A. Appearance
• B. Work of breathing
• C. Circulation to the skin
• D. Blood pressure

Answer: (A)

The main idea here is the Pediatric Assessment Triangle, a rapid bedside framework that looks at three performance-based domains to quickly gauge a child’s condition. Those three domains are appearance, work of breathing, and circulation to the skin.

Appearance is about how alert or responsive the child is, their interaction with you, and their color or tone, giving a quick sense of mental status and overall well-being. Work of breathing assesses how hard the child is breathing—effort, rhythm, work with accessory muscles, and any abnormal sounds—which helps identify respiratory distress or failure. Circulation to the skin checks skin color and perfusion, indicating how well blood is reaching the skin and whether there might be shock or poor perfusion.

Blood pressure is important, but it’s not one of the three components of the PAT; it’s a separate vital sign you gather as part of ongoing assessment. So the concepts that fit into the PAT are appearance, work of breathing, and circulation to the skin; blood pressure stands outside of this triangle. If you had to pick any single choice that aligns with the PAT, each of those first three options would fit, since they are all parts of the triangle.
