Question answers should be based on evidence found in readings and from peer-reviewed literature. At least two sources must be used and cited in APA format for each question. Only one source can be a textbook. Resources should generally be within 5 years unless you are explaining the pathophysiology of a disease or providing pertinent background information.

Discussion Questions:

  1. Explain the action of thyroid hormone and how this impacts the diagnosis. Your answer should contain the impact of the thyroid hormone on functions in the body.
  2. As Thyroid Stimulation Hormone (TSH) levels rise, explain how this impacts the negative-feedback mechanism in the body.
  3. What are the roles of Thyroxine (T4) and triiodothyronine (T3) in the body?
