Unit 12: Nursing care of clients with endocrine disorders

QuestionAnswer
Addison's disease: (Pg. 904) Adrenocortical insufficiency; caused by damage/dysfunction of adrenal cortex -Mineralcorticoid production & glucocorticoid production is diminished -Low aldosterone & cortisol
Adrenal cortex produces..? Mineralcorticoids (aldosterone), glucocorticoids (cortisol), & sex hormones (adrogens & estrogens)
What is acute adrenal insufficiency known as? Addisonian crisis -rapid onset -medical emergency
Primary causes of addison's disease: Idiopathic autoimmune (majority) Tuberculosis (Adrenal) Histoplasmosis Adrenalectomy Cancer
Secondary causes of Addison's disease Steroid withdrawal, hypophysectomy, pituitaery neoplasm
Chronic addison's disease s/s develop slow or fast? Slowly
S/s: (Pg. 905) wt, craving, color, activity BP, fluids Wt loss, salt craving (low sodium), hyper pigmentation, weak/fatigue Nausea/vomit, dizzy orthostatic hypotension, dehydration
S/s con't: natremia, kalemia, glycemia, calcemia Hyponatremia, hyperkalemia, hypoglycemia, hypercalcemia
Lab tests: electrolytes & ACTH test ATCH infused & cortisol response measured 30 minutes after & 1 hr after -If primary adrenal insufficiency, no rise in cortisol
Dx addison's: ECG ECG lyte imbalances; potassium; dysrhythmias x-ray, ct, mri, radiography (tumor)
Nursing actions: -Fluid imbalances -Lyte imbalances -Saline infusions, orthostatic VS, hydrocortisone bolus -Monitor & treat hyperkalemia; serum k+ & ECG -Give sodium polustyrene sulfonate (Kayexalate), insulin, calcium, glucose & sodium bicarb
Medications: (Pg. 906) Hydrocortisone (Cortef), prednisone (Deltasone), and cortisone -what are they & what to monitor Glucocorticoid; used as an adrenocorticoid replacement for adrenal insufficiency & as anti-inflammatory -wt, bp, lytes -^ dosage during stress/illness -taper dose if discontinuing to avoid acute renal insufficiency -give w food
Symptoms of cushing's syndrome? (might come w glucocorticoid use) wt gain, edema, moon face
Fludrocortisone (Florinef) Mineralcorticoid; replacement in adrenal insufficiency -wt, bp, lytes, htn, ^ dose during stress/illness
