17
Q

exophthalmometry

A

Measures the degree of forward displacement of the eyeball (exophthalmos) as seen in graves disease

18
Q

parathyroidectomy

A

excision of one or more of the parathyroid glands, usually to control hyperparathyroidism

19
Q

transsphenoidal hypophysectomy

A

endoscopic procedure to surgically remove a pituitary tumor through an incision in the sphenoid sinus (transsphenoidal) without disturbing brain tissue

20
Q

thymectomy

A

excision of the thymus gland

21
Q

thyroidectomy

A

excision of the entire thyroid gland (thyroidectomy), a part of it (subtotal thyroidectomy), or a single lobe (thyroid lobectomy)

22
Q

fasting blood sugar

A

test that measure glucose levels in a blood sample following a fast of at least 8 hours

23
Q

glucose tolerance test (GTT)

A

screening test in which a dose of glucose is administered and blood samples are taken afterward at regular intervals to determine how quickly glucose is cleared from the blood

24
Q

insulin tolerance test (ITT)

A

diagnostic test in which insulin is injected into the veins to assess pituitary function, adrenal function, and to determine insulin sensitivity

25
Q

thyroid function test (TFT)

A

test that detects an increase or decrease in thyroid function

26
Q

total calcium test

A

test that measures calcium to detect bone and parathyroid disorders

27
Q

computed tomography (CT)

A

imaging technique that rotates an x-ray emitter around the area to be scanned and measures the intensity of transmitted rays from different angles

28
Q

magnetic resonance imaging (MRI)

A

noninvasive imaging technique that uses radio waves and a strong magnetic field, rather than an x-ray beam, to produce multiplayer cross-sectional images

29
Q

radioactive iodine uptake (RAIU)

A

administration of a radioactive iodine (RAI) in pill or liquid form is used as a tracer to test how quickly the thyroid gland takes up (uptake) iodine from the blood

30
Q

Thyroid scan

A

images of the thyroid gland are obtained after oral or intravenous administration of a small dose of radioactive iodine

31
Q

antidiuretics

A

reduce or control excretion of urine

32
Q

antithyroids

A

treat hyperthyroidism by impeding the formation of T3, and T4 hormone
antithyroid are administered in preparation for thyroidectomy and in thyrotoxic crisis

33
Q

corticosteroids

A

replace hormones lost in adrenal insufficiency (addison disease)
widely used to suppress inflammation, control allergic reactions, reduce rejection in transplantation, and treat some cancers.

34
Q

growth hormone replacements

A

increased skeletal growth in children and growth hormone deficiencies in adults
growth hormones increase spinal bone density and help manage growth failure in children

35
Q

insulins

A

lower blood glucose levels by promoting its entrance into body cells and converting glucose to glycogen (a starch- storage form of glucose) Type 1 diabetes must always be treated with insulin. insulin can also be administered through an implanted pump

36
Q

oral antidiabetics

A

treat type 2 diabetes mellitus by stimulating the pancreas to produce more insulin and decrease peripheral resistance to insulin
Antidiabetic drugs are not insulin and they are not used in treating type 1 diabetes mellitus

37
Q

thyroid supplements

A

replace or supplement thyroid hormones each thyroid supplement contains T3, T4, or a combination of bath. Thyroid supplement are also used to treat some types of thyroid cancer.
