Question 1 Type: MCSA 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 Correct Answer: 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.
