Aclient, visiting the health center, reports feeling nervous, irritable, and extremely tired. the client says to the nurse, "although i eat a lot of food, i have frequent bouts of diarrhea and am losing weight." the nurse observes a fine hand tremor, an exaggerated reaction to external stimuli, and a wide-eyed expression. what laboratory tests may be prescribed to determine the cause of these signs and symptoms?

So basing upon the given signs and symptoms above, I can say that the suggested laboratory tests that the patient should undergo include T3, T4, and thyroid-stimulating hormone (TSH). This is actually a blood test that measures these hormones. Given the symptoms, these indicate that the client has an increase of the production of these hormones. Generally, these hormones are released by the pituitary gland and they play an important role in the body's metabolism.
