Endocrine NUR 200 (Thyroid Gland, And Adrenal
Glands) – Questions With Correct Answers
Hormones the thyroid secretes Right Ans - 1. T3
2. T4
3. Calcitonin
T3/T4 Right Ans - - helps with metabolic activity
Calcitonin Right Ans - - brings down serum Ca levels, brings Ca into the
bones
- "tones" down the Ca
if Thyroid hormone levels are elevated Right Ans - - TSH will be decreased
TSH Right Ans - - stimulates thyroid gland to secrete more T3/T4
pituitary tumors Right Ans - - T3/T4 elevated *AND* TSH elevated =
problem is in pituitary gland
thyroid problem Right Ans - - if T3/T4 elevated and TSH decreased or
normal = problem is in thyroid
Adrenal glands Right Ans - 1. adrenal medulla
2. adrenal cortex
Adrenal medulla Right Ans - - secretes:
1. Epinephrine
2. Nor-epinephrine
purpose of adrenal medulla Right Ans - "fight or flight" response
--> short-term stress response
Adrenal cortex Right Ans - - secretes:
1. Cortisol *sugar* (glucocorticoids)
2. Aldosterone *salt* (mineralocorticoids)
3. Androgens *sex* (sex hormones)
, purpose of adrenal cortex Right Ans - - Long-term stress response
- cortisol: makes more glucose available, increases deposition of fat around
midsection.
- aldosterone: makes kidneys retain salt and water, increasing BP,
maintenance of BP over long time.
Adrenocorticotropic hormone ACTH Right Ans - - functions just like TSH
stimulates adrenal cortex to release cortisol and aldosterone
- from ANTERIOR pituitary
Adrenal gland issues Right Ans - 1. Addison's
2. Cushing's
Addison's: what is it? Right Ans - - a decreased amount of cortisol and
aldosterone
- you need to "ADD" more hormones
Addison's: Na, BP, Blood sugar Right Ans - - decreased Na, BP, Blood sugar
Addison's: K, Ca Right Ans - - increased K, Ca
Addison's: cravings Right Ans - - salt cravings
Addison's: skin Right Ans - - hyper-pigmentation
Addison's: fluid volume Right Ans - - fluid volume deficit
Addison's: weight Right Ans - - weight loss
Addison's: treatment Right Ans - - Florinef (fludrocortisone)
- these replace Aldosterone
- can use Kayexlate to decrease K levels
- insulin/glucose to pull K into the cells
Addisonian's crisis Right Ans - - acute DROP in adrenocorticoids
- caused by trauma, infection, stress
- *rapid, emergency*
