A patient is diagnosed with Hashimoto thyroiditis and asks what causes it. The nurse would respond that the destruction of thyroid cells in this condition is due to which of the following?

Autoantibodies
Viral infection
Bacterial infection
The Correct Answer is A
A. Antigen-antibody complexes: These are involved in Type III hypersensitivity reactions, not in Hashimoto thyroiditis.
B. Autoantibodies: Hashimoto thyroiditis is an autoimmune disorder where autoantibodies target thyroid peroxidase (TPO) and thyroglobulin, leading to inflammation and destruction of thyroid cells.
C. Viral infection: Although some autoimmune conditions may have viral triggers, Hashimoto's is not directly caused by a viral infection.
D. Bacterial infection: Bacterial infections do not cause Hashimoto thyroiditis.
