Final answer:
The early high white blood cell (WBC) count is normal at birth and should decrease rapidly.
Step-by-step explanation:
The correct answer is b. The early high white blood cell (WBC) count is normal at birth and should decrease rapidly. At birth, infants have a high WBC count, which is a normal response to the stress of birth. This high count helps protect the newborn against potential infections in the early days of life.
However, this elevated count should decrease rapidly within the first few days as the baby adapts to the outside environment. If the WBC count stays consistently high or continues to rise after the first few days, it could indicate an infection or other underlying medical condition that requires further medical attention.
