If all three sides are involved in the pediatric assessment triangle, the patient is in which condition?

• A. Cardiopulmonary failure
• B. Sepsis
• C. Respiratory failure
• D. Neuromuscular failure

Answer: (A)

In pediatrics, the rapid Pediatric Assessment Triangle looks at appearance, work of breathing, and circulation to the skin. If all three are abnormal, oxygen delivery and perfusion are severely compromised, which is cardiopulmonary failure. This pattern means the child is experiencing simultaneous respiratory and circulatory collapse, requiring immediate airway, breathing, and circulation support. Sepsis or respiratory failure can cause serious illness, but the combination across appearance, breathing effort, and skin perfusion most directly points to cardiopulmonary failure, whereas neuromuscular failure or isolated respiratory failure would not typically involve all three areas together to the same extent.
