Endocrine Flashcards
pituitary gland location
base of brain
adrenal gland location
top of kidneys
thyroid gland location
anterior part of neck
parathyroid gland location
on thyroid gland
pancreas location
posterior to stomach
pituitary gland function
promotes body tissue growth. water absoprtion by kidney. sexual development and function.
adrenal gland function
sodium and electrolyte balance.
thyroid gland function
body metabolism rate. produces T3 and T4
parathyroid gland function
controls calcium and phosphorus metabolism
pancreas function
carb metabolism. produces insulin and glucagon
hemoglobin a1c (glycosylated hemoglobin a) meaning
how well blood glucose has been controlled for the past 3-4 months (90-120 days)
hypopituitarism patho
decreased secretion of pituitary hormones
hypopituitarism s/s
obesity. reduced cardiac output. sexual dysfunction. low blood pressure. fatigue. tumors.
hypopituitarism care
hormone replacement. emotional support.
hyperpituiitarism (acromegaly) patho
increase secretion of growth hormone usually caused by tumors
hyperpituiitarism (acromegaly) s/s
large hands and feet. thick and protruding jaw. joint pain. arthritis. visual changes. sweating. pily rough skin. prganomegaly. hypertension. atherosclerosis. cardiomegaly. heart failure. dysphagia. deepening in voice. thick tongue. narrowing airway. sleep apnea. increase blood sugar. colon polyps
hyperpituiitarism (acromegaly) care
radiation. removal of pituitary tumor (hypophysectomy). care for arthritis.
hypophysectomy
removal of pituitary tumor via craniotomy
hypophysectomy complications
IICP. bleeding. meningitis. hypopituitarism.
hypophysectomy post op care
neuro checks.
elevate HOB
check for IICP
check and report s/s DI (excessive urine output)
antibiotics
pain and fever meds
oral mouth rinse
no toothbrush or use ultra soft toothbrush for 10 days to 2 weeks
REPORT POSTNASAL DRIP OR CLEAR NASAL DRAINAGE = CSF
diabetes insipidus patho
decrease secretion of ADH (vasopressin, antidiuretic hormone)
diabetes insipidus s/s
large amounts of diluted urine. polydipsia. dehydration. decreased skin turgor. dry mucous membrane. low urine specific gravity. fatigue. ortho hypotension. tachycardia.
diabetes insipidus care
INCREASE FLUIDS. monitor I&O daily weights and specific gravity. VS. neuro checks. cardiac status. safe environment. check for s/s dehydration. give vasopressin or desmopressin (watch for water intoxication s/s of headache and confusion)
SIADH patho
syndrome of inappropriate antidiuretic hormone secretion
too much ADH released
SIADH s/s
syndrome of inappropriate antidiuretic hormone secretion
may cause cerebral edema. at right for seizures. fluid volume overload. changes in loc. weight gain without edema. hypertension. tachycardia. n/v. hyponatremia. low urine output. concentrated urine
SIADH care
syndrome of inappropriate antidiuretic hormone secretion
RESTRICT FLUIDS. loop diuretics to promote diuresis BUT ONLY IF SODIUM IS AT LEAST 125. vasopressin antagonist. check cardiac and neuro. safe environment. check for IICP. seizure precautions. elevate HOB to 10 degrees. I&o. daily weights.
addison’s patho
decreased secretion of adrenal cortex hormones: kidney (gluucocorticoids, mineralocorticoids, androgen)
addison’s s/s
dehydration. hypotension. hyponatremia.
hyperkalemia. hypercalcemia.
fatigue. weight loss. GI issues. bronze hyperpigmentation of skin
addison’s care
I&O. weight.give glucocorticoid/mineralocorticoid.
monitor for addisonian crisis . lifelong glucocorticoid replacement (increase during stressful times). avoid people with infections. no strenuous exercise because it is stress on body. high protein and carb diet. calcium and vit d supplements.
addisonian crisis
life threatening adrenal insufficiency caused by stress infection trauma surgery or withdrawal of corticosteroid use.
addisonian crisis s/s
hyponatremia. hyperkalemia. hypoglycemia. shock. weakness. irritable. confused. severe headache. severe abdominal leg and back pain
addisonian crisis care
glucocorticoids IV. IVF. restore electrolyte balance. neuro checks. I&O. prevent infection. bed rest. quiet environment.
cushings (hypercorticolism) patho
increased production of cortisol or giving too much glucocorticoids for long periods
cushings (hypercorticolism) s/s
hyperglycemia. hypernatremia. hypertension. hypokalemia. hypocalcemia. muscle wasting. weak. moon face. buffalo hump. obese stomach and thin legs. weight gain. hirsutism (male features in a woman). fragile skin that bruises easily. red purple striae on abdomen and thighs
cushings (hypercorticolism) care
I&O. weights. radiation. hypophysectomy. adrenalectomy with lifelong glucocorticoid replacement. protect from post op thrombus.
pheochromocytoma patho
catecholamine producing tumor on adrenal medulla (kidneys) that secretes increased amounts of epi and norepi
pheochromocytoma testing
24 hr urine: keep on ice. get rid of 1st void then collect every urine for 24 hrs. if one void is discarded or missed the test is restarted.
pheochromocytoma s/s
hypertension. severe headaches. palpitations. flushing. sweating. chest or abdomen pain. n/v. heat intolerance. weight loss. tremors. hyperglycemia.
pheochromocytoma care
adrenalectomy. monitor for hypertensive crisis. no smoking. no caffeine. no changing position quickly. give beta blockers for hypertension. check blood sugar. rest. quiet environment. high calorie mineral and vitamin diet.
* *AVOID STIMULI THAT CAN CAUSE HYPERTENSIVE CRISIS SUCH AS ABDOMINAL PRESSURE AND VIGOROUS ABDOMINAL PALPATION**
adrenalectomy
surgical removal of adrenal gland on the kidneys. will only need life long glucocorticoid and mineralcorticoid replacement if there is a removal of both glands.
