Clinical Medical Assistant Certification Exam Practice Question

Correct Answer: C

Rationale: Graves' disease is an autoimmune disorder that leads to hyperthyroidism, characterized by symptoms such as goiter (enlarged thyroid), exophthalmos (protruding eyes), and thyrotoxicosis (excess thyroid hormones).

Acromegaly results from excess growth hormone, leading to enlarged features, not thyroid issues. Cushing's disease involves excessive cortisol, causing symptoms like weight gain and high blood pressure, unrelated to thyroid function. Hashimoto's thyroiditis is an autoimmune condition leading to hypothyroidism, causing a goiter but not typically exophthalmos or thyrotoxicosis. Myxedema refers to severe hypothyroidism, presenting with different symptoms altogether.
