Endocrine 2 Flashcards
All pituitary activities controlled by what
hypothalamus
what hormone promotes growth indirectly, control of protein, lipid, carbohydrate metabolism, found in liver and adipose tissue
growth hormone
what hormone stimulates secretion of thyroid hormones and is found in thyroid gland
thyroid stimulating hormone
what hormone stimulates the secretion of corticosteroids, found in adrenal gland and cortex
adrenocorticotropic hormone
what hormone stimulates milk production, lactogenic hormones, found in mammary gland
prolactin hormone
what hornome controls reproduction function, found in ovary and testes
gonadotropic hormones
what hormone stimulates target organs to release hormones, growth and development
B-lipotropin hormone
what hormone is a major participant in several physiologic processes including growth and metabolism
Growth hormone (somatotropin)
the thyroid stimulating hormone is controlled by _____ which secretes ________
hypothalamus
TRH (thyrotropin releasing hormone)
the growth hormones most intense release in children and young adults is when
after onset of deep sleep
normal IQ, stunted growth, delayed puberty, excessive sub Q fat, poor muscle development, hyposecretion of growth hormone during childhood
hypopitutarism
(pititary dwarfism)
oversecretion of one or more of the pituitary horomes, growth hormone or prolactin
hyperpituitarism
what stimulates sgowth in bones and soft tissue and normally signals anterior pituitary to reduce growth hormone production
insulin growth factors
tumor compresses normaltissue, secretion decreases
pituitary tumors (most common)
testosterone secretion by interstitial cells testes
cales- leydig cells of testes
in childhood gigantism happens because what
there is an excess of growth hormone before the closure of the epiphyseal plate
when does acromegaly develop
after epiphyseal closure, so bones and soft tissue thicken
patients with acromegaly need what kind of diet to avoid heart failure
low sodium diet
what are complications of acromegaly
arthrosclerosis, DM, cardiomegaly
what signs and symptoms would you find with a patient who has acromegaly
c/o changes in dentures, hat, glove, rins, shoe size
in patients with acromegaly can bone growth stop, soft tissue, and hypertrophy be reversed
yes
what nursing management would you do for acromegaly
increased calcium diet, good skin care, and psycological support
ADH is regulated by what
plasma osmolality & blood volume
stimulates uterine smooth muscle contraction to facilitate birth, milk ejection
oxytocin
ADH is released depsite normal or low plasma osmolarity, results from abnormal production or sustained secretion of ADH
SIADH
(syndrome of inappropriate ADH)
in SIADH there is decreased NA which leads to what
muscle cramps, weakness, anorexia, nausea, diarrhea, HA, confustion, irritability
in SIADH, water retention leads to what
water intoxication, brain swells leading to neuro issues (lethargy, seizures, and coma)
what are SIADH pts given diuretics
they may develop heart failure
excrete large amounts of dilute urine with glucose (no glucosuria)
diabetes insipidus
what assessments would you do with a diabetes insipidus patient
assess:
B/P, skin turgor, I & O, daily weight
butterfly shaped fland located anterior portion of neck in front of trachea
thyroid gland
what is necesssary for synthesis of thyroid hormones
iodine
the tyroids function is for production, storage, realease of three hormones that regulate metabolic processes, they are?
T-4, T-3, calcitonin
inhibits resorption from bone, incrases bone storage & renal excretion of Ca & phosphorus
calcitonin
what is the first diagnostic test for hormone dysfunction of the thyroid gland
TSH serum study, most sensitive
sustained increase of synthesis and release of thyroid hormone by thyroid gland
hyperthyroidism
autoimmune disease, diffuse thyroid enlargement & excessive thyroid hormone secretion
graves disease
a condition of neuromuscular hyperexcitability associated with sudden decrease in calcium levels,
tetany
characterized by unpleaseent tingling of the hands and aound the mouth
tetany
can toxic nodular goiters be multinodar goiter or single nodule
both
what are clinical manifestations of hyperthyroidism
