Hypothyroidism
Results when GH is over secreted after the epiphyses of the long bones have sealed.
Acromegaly

Pituitary gland
When overseeing of GH occurs before puberty __ results
Gigantism
When secretion of GH during childhood is insufficient __ occurs
Dwarfism
Oversecretion of GH during adulthood results in ___
Acromegaly
An absence of pituitary hormonal activity causes ___ or ___ disease
Panhypopituitarism
Simmonds
Acromegaly results when GH is oversecreted after epiphyses of the long bones have sealed. GH is over produced when the pituitary gland is insensitive to feedback inhibit hormones such as ____, a hypothalamic hormone, and insulin like growth factor (IGF-1)
Somatostatin
___ in combination with a __ is the most reliable method of confirming acromegaly
Glucose tolerance test
GH measurement
Acromegaly
The Tx of choice is ___ (surgical removal of pituitary gland)
Hypophysectomy
Pituitary gland lies within the __, a saddle shaped depression of the __ bone
Sella turcica
Sphenoid
A GH receptor antagonist, is the newest and most effective drug for treating acromegaly. Injected subcut once a day
Pegvisomant
A rare disorder caused by destruction of the pituitary gland followed by cessation of pituitary hormonal activity (complete stop of the pituitary hormone)
Panhypopituitarism (simmonds disease)
The __ and __ atrophy because of the impaired pituitary stimulus, the thyroid and adrenals fail to secreted adequate hormone
Gonads
Genitalia
The __ and __ atrophy because of the impaired pituitary stimulus, the thyroid and adrenals fail to secreted adequate hormone
Gonads
Genitalia
Signs and symptoms of hypothyroidism, hypoglycemia, and adrenal insufficiency are apparent, the client agen prematurely
Panhypopituitarism (simmonds disease)
Nursing management with panhypopituitarism (simmonds disease)
Administer all HRT as prescribed. Teach pt to adhere to the med schedule and never omit a dose
A disorder characterized by the excretion of extremely large volumes of urine.
Diabetes insipidus
Requested the reabsorption of water in the kidney tubules. It’s function is to increase circulating fluid volume
ADH
Released as a response to thirst, fluid losses (hemorrhage), which lowers BP
ADH
Lack of __ or ineffective response to it causes the client to produce large volumes of dilute urine
ADH
Urine output may be as night as 20 L/24 hr. Urine is dilute with a spec gravity of 1.002 or less
Diabetes insipidus (DI)
At the completion of the fasting phase of the test, the pt received an infusion of desmopressin acetate (DDAVP), a synthetic analogue of vasopressin
Diabetes insipidus (DI)
The provider restricts the client’s use of dietary sodium and prescribes a thiazide diuretic such as hydrochlorothiazide (hydroDIURIL)
Diabetes insipidus (DI)
Characterized by renal reabsorption of water rather than its normal excretion
Syndrome of inappropriate antidiuretic hormone secretion (SIADH)
In SIADH, the continues release of ADH increased fluid volume and causes ___
Hyponatremia
SIADH =
Weight gain
