The thyroid gland is located in our neck and secretes various hormones responsible for regulating the metabolic rates and assisting in protein synthesis in mammals. The following quiz is designed to test your knowledge on the various diseases that affect the thyroid gland. Good Luck!


Questions and Answers
  • 1. 
    Despite the availability of a wide array of thyroid hormone products, it is clear that ___________ is the treatment of choice for almost all patients with hypothyroidism.
    • A. 

      Liothyronine (Cytomel)

    • B. 

      Liotrix (Thryolar)

    • C. 

      Synthetic levothyroxine (LT4)

    • D. 

      Desiccared Thyroid (Armour, etc)

    • E. 

      None of the above

  • 2. 
    Iodine deficiency can result in ________.
  • 3. 
    The thyroid gland is the largest endocrine gland in the body, residing in the neck, anterior to the trachea.  It produces two biologically active hormones, T4 and T3.  Most of the physiologic activity of thyroid hormones is from the actions of ____.
    • A. 

      T4

    • B. 

      T3

  • 4. 
    80% of thyroid hormone is synthesized as T4 and stored in the thyroid bound to thyroglobulin.  Thyroid hormones are released from the gland when needed, primarily under the influence of _____ from the anterior pituitary. 
    • A. 

      TSH (thyrotropin)

    • B. 

      Thryoid binding globulin (TBG)

      Transthyretin

    • B. 

      Primary hyperthyroidism, Primary hypothyroidism

  • 8. 
    A radioactive iodine uptake test helps determine intrinsic thyroid function.  A thyroid scan can help distinguish etiology (such as cancer).  A TRH stimulation test helps determine thyroid and ________ function.
