hypofunction assessment
failure of hormone level to rise w stimulation
suppression tests
used when hormone levels are high or upper range off normal
hyperfunction assessment
failure of suppression of hormone production during testing
assay test
measures the level of a specific hormone in blood or other body fluid
age related changes-4
- decreased ADH production
- decreased estrogen production
- decreased glucose tolerance
- decreased general metabolism
24 hour urine specimen test-6
- start by emptying bladder, don’t save, start timer
- collect all urine, including last, to end
- check w lab for special instructions
- preservative added at beginning if indicated
- preservative may be caustic-don’t splash
- place in seperate cooler w ice if indicated
hyperpituitary ass- multiple endocrine neoplasia type 1
- autosomal dominent inheritance usually expressed as benign tumor
- excess GH and acromegaly
- backache, joint pain, headaches, changes in vision
acromegaly-4
- gradual progression
- thick lips, coarse facial features, increased head size, lower jaw protrusion, enlarged hands and feet, heart and liver enlargement
contraindications for testosterone tx
prostate cancer
-side effects gynecomastia, acne, baldness, and prostate enlargement
bromocriptine mesylate education
-hyperpituitarism-4
- stim dopamine and inhibit GH and PRL
- orthostatic hypotension, gastric irritation, nausea, headaches, abdo cramps, and constipation
- take w food, no pregnancy
- med emergency- chest pain, dizziness,watery nasal discharge
hypophysectomy post-op care-6, 6 don’ts
- hourly neuro checks
- fluid balance
- encourage deep breathe
- don’t: cough, sneeze, blow nose, brush teeth, bend at waist, constipation strain
- monitor nasal drip pad for type and amt of drainage
- teach self admin of hormones
DDAVP
- synthetic vasopressin (ADH)
- treatment for DI, restricts water loss-> can cause fluid overload
- watch for weight gain more that 2.2lb
conivaptan effect eval (SIADH)
- vasopressin antagonists that promote water excretion w/o causing Na loss
- only in hosp-watch for hypernatremia, fluid overload, pulmonary edema, change in LOC
adrenal adenoma
- increased secretion of aldosterone
- hypernatremia, hypokalemia, metabolic alkalosis
- HTN, headache, fatigue, muscle weak, dehydration
adrenal adenoma labs
- Low- K, renin, urine sp grav
- high- Na, aldosterone, pH
