What symptom may a psychiatric technician observe in a client diagnosed with Graves' Disease?

Clients diagnosed with Graves' Disease often exhibit exophthalmos, which is characterized by protruding eyes. This condition arises from an overproduction of thyroid hormones, leading to an autoimmune response that affects the muscles and fat behind the eyes. The inflammation and swelling in that area result in the characteristic bulging of the eyes. This symptom is notable because it is specific to Graves' Disease among other thyroid-related issues and helps in identifying the condition.

In contrast, symptoms such as bradycardia, jaundice, and hypertension are associated with different medical conditions or thyroid dysfunctions, but they do not distinctly identify Graves' Disease. Bradycardia refers to a slower-than-normal heart rate, which is typically linked to hypothyroidism rather than the hyperthyroid state seen in Graves' Disease. Jaundice indicates liver dysfunction, unrelated to the thyroid's effects, while hypertension can occur in various conditions and is not a hallmark symptom of Graves' Disease specifically. Thus, exophthalmos is the key symptom that psychiatric technicians should recognize in clients with this diagnosis.
