In pediatric triage, which abnormal vital sign pattern is most concerning for shock?

• A. Hypotension is an early sign
• B. Tachycardia out of proportion to fever with delayed capillary refill
• C. Bradycardia with normal cap refill
• D. Normal vitals

Answer: (B)

In pediatric triage, shock is most concerning when perfusion is clearly impaired, and the body is trying to compensate. The strongest signal is a heart rate that is disproportionately high for the degree of fever, paired with delayed capillary refill. This pattern shows the child is mounting a tachycardic response to hypoperfusion, yet the tissues aren’t getting blood flow efficiently, as shown by the sluggish refill. Blood pressure can remain normal early on in kids, so relying on hypotension as the warning sign would miss the early, treatable stage of shock. Conversely, bradycardia with normal capillary refill or normal vitals except for one abnormal finding does not align with the typical early shock pattern. Together, tachycardia out of proportion to fever with delayed capillary refill best indicates early shock and urgent need for assessment and intervention.
