• B. Neurogenic shock
• C. Cardiogenic shock
• D. Hypovolemic shock

Answer: (D)

Verified step by step guidance

1. Step 1: Understand the concept of shock. Shock is a life-threatening condition where the body is not getting enough blood flow, leading to insufficient oxygen and nutrients for tissues and organs.
2. Step 2: Review the types of shock. Anaphylactic shock is caused by severe allergic reactions, neurogenic shock results from damage to the nervous system, cardiogenic shock is due to heart failure, and hypovolemic shock occurs due to significant blood or fluid loss.
3. Step 3: Focus on hypovolemic shock. Hypovolemic shock is the most common type of shock in children and infants because they are more susceptible to dehydration and blood loss due to their smaller blood volume and higher metabolic rate.
4. Step 4: Relate hypovolemic shock to cardiac arrest. In children and infants, cardiac arrest is often secondary to respiratory failure or hypovolemia, which leads to inadequate circulation and oxygen delivery to the heart and other vital organs.
5. Step 5: Conclude that hypovolemic shock is the correct answer based on its prevalence in pediatric cases and its direct association with cardiac arrest in children and infants.
