Question 1
In a type III hypersensitivity reaction, the harmful effects after the immune complexes that are deposited in tissues are a result of what?
◦ Cytotoxic T cells
◦ Natural killer cells
◦ Complement activation
◦ Degranulation of mast cells
Question 2
A healthcare professional is teaching a patient about Raynaud phenomenon and instructs the patient to avoid cold. What is the best explanation of how cold impacts the manifestations of this disease?
◦ Immune complexes that are deposited in capillary beds, blocking circulation
◦ Mast cells that are bound to specific endothelial receptors, causing them to degranulate and creating a localized inflammatory reaction that occludes capillary circulation
◦ Cytotoxic T cells that attack and destroy the capillaries so that they are unable to perfuse local tissues
◦ Antibodies that detect the capillaries as foreign protein and destroy them using lysosomal enzymes and toxic oxygen species
Raynaud’s disease.
