Which is an early sign of shock in a child who has been involved in a car accident?

• A. Anxiety with normal BP
• B. Hypotension
• C. Lethargy
• D. Bradycardia

Answer: (D)

In pediatric shock, the body’s first response to reduced perfusion is to compensate by increasing the heart rate. Tachycardia is usually the earliest and most reliable sign that a child is not perfusing properly. Blood pressure tends to stay normal until later stages, while other signs such as rapid breathing, cool or mottled skin, delayed cap refill, anxiety or restlessness, and fatigue or lethargy can appear as perfusion worsens. As shock progresses and the child decompensates, the heart can no longer compensate, and the heart rate may fall—bradycardia—which is a dire sign that the child is near cardiac arrest or has severe hypoxia or brain injury. So, an early sign you’d look for after trauma is a rising heart rate rather than a slowing one. If bradycardia is observed, it indicates deterioration requiring immediate resuscitation and aggressive support rather than an early, compensatory response. In practice, treat the child as if shock is present: secure the airway, provide oxygen, establish IV access, monitor closely, control any bleeding, and transport urgently for definitive care.
