Pediatric ATI Practice Exam

What is the typical range for pediatric platelet counts?

1. 100,000-300,000

2. 150,000-400,000

3. 200,000-500,000

4. 250,000-600,000

The correct answer is: 150,000-400,000

The typical range for pediatric platelet counts is generally recognized as 150,000 to 400,000 platelets per microliter of blood. This range is crucial for monitoring a child’s blood health and ensuring proper functioning of the hemostatic system. Platelets play a vital role in blood clotting and wound healing, and understanding the normal range helps in identifying potential clotting disorders or thrombocytopenia (low platelet count) in pediatric patients. The selected range allows healthcare providers to assess new conditions or track existing ones effectively. Different age groups can have varying reference ranges, and pediatric reference ranges sometimes differ from adult ranges due to differences in physiology and growth patterns; thus, using a specific pediatric range is essential for accurate diagnosis and treatment.
