In children diagnosed with sickle cell disease (SCD), tissue damage results from which of the following?
- A. Air hunger and respiratory alkalosis due to deoxygenated red blood cells.
- B. Hypersensitivity of the central nervous system (CNS) due to elevated serum bilirubin levels
- C. A general inflammatory response due to an autoimmune reaction from hypoxia
- D. Local tissue damage with ischemia and necrosis due to obstructed circulation
Correct Answer: D
Rationale: In children diagnosed with sickle cell disease (SCD), tissue damage results from local tissue damage with ischemia and necrosis due to obstructed circulation. Sickle cell disease is a genetic disorder characterized by abnormal hemoglobin that causes red blood cells to assume a sickle shape. These sickle-shaped cells can adhere to blood vessel walls, leading to vaso-occlusion and impaired blood flow. This obstruction results in tissue ischemia and eventual necrosis, causing significant pain and organ damage. The chronic vaso-occlusive events in SCD are responsible for the development of acute and chronic complications seen in affected individuals, such as painful crises, stroke, and organ damage.
