Which of the following best describes the components of the Pediatric Assessment Triangle (PAT)?

• A. Appearance
• B. Work of breathing
• C. Circulation to the skin
• D. All of the above

Answer: (D)

PAT is a rapid visual assessment of a child that evaluates three domains to gauge stability: Appearance, Work of breathing, and Circulation to the skin. Appearance looks at how the child is alert and interactive, which reflects mental status and overall well-being. Work of breathing examines respiratory effort and signs of distress such as nasal flaring, grunting, or use of accessory muscles. Circulation to the skin checks perfusion by looking at skin color and temperature for signs like pallor, mottling, or cyanosis. Because distress in a pediatric patient can appear in more than one area at once, the best description is that the Pediatric Assessment Triangle comprises all three components. Focusing on just one domain could miss critical signs that show up in the other domains, such as a child who looks fairly normal but has poor perfusion or significant respiratory effort.
