A patient is admitted with a large, inflamed leg wound. The nurse explains that the inflammatory response is initiated by chemicals released by which white blood cell type?
1. Monocytes
2. Eosinophils
3. Basophils
4. Neutrophils
3
Rationale 1: Monocytes arrive at the site of an injury hours or days after the neutrophils and continue to consume large amounts of cellular debris.
Rationale 2: The number of eosinophils increases in the presence of parasites and allergies. They enhance the inflammatory response rather than initiate it.
Rationale 3: Basophils migrate from the bloodstream into tissue and mature into mast cells. When a body cell is injured, mast cells in the immediate vicinity release large quantities of histamine, stimulating the inflammatory response.
Rationale 4: Neutrophils are phagocytic and consume cellular debris and bacterial and viral particles. They are the first group of WBCs to arrive at a site of injury or cell death in response to chemical signals.
