  1. 6 functions of the endocrine system
    • maintenance and regulation of vital functions
    • response to stress and injury
    • growth and development
    • energy metabolism
    • reproduction
    • fluid, electrolyte and acid-base balance
  2. addisonian crisis
    • caused by adrenal hormone insufficiency
    • Precipitated by infection, trauma, stress, or surgery
    • Death can occur from shock, vasular collapse, or hyperkalemia
  3. addisons disease
    • hyposecretion of adrenal cortex hormones (glucocorticoids and mineralocorticoids) from adrenal gland
    • fatal if untreated
  4. chvosteks sign
    • spasm of the facial muscles elicited by tapping the facial nerve just anterior to the ear
    • noted with hypocalcemia
  5. cushings syndrome
    hypersecretion of glucocorticoids from adrenal cortex
  6. dawn phenomenon
    • results from nocturnal release of GH
    • may cause elevated blood sugar before breakfast
  7. diabetes insipidus
    hyposecretion of ADH from posterior pituitary gland
  8. diabetes mellitus
    • glucose intolerance
    • impaired carb, protein, and lipid metabolism caused by insulin resistance or insulin deficiency
  9. diabetic ketoacidosis
    • develops when severe insulin deficiency occurs
    • progressives from hyperglycemia after several hrs to days
    • occurs in type 1 DM, undiagnosed DM, and people who stop taking prescribed treatment for DM
  10. hyperglycemic hyperosmolar nonketotic syndrome
    • extreme hyperglycemia w/o acidosis
    • complication of type 2 DM
    • takes hrs to days to onset
  11. hypophysectomy
    removal of pituitary gland
  12. myxedema
    • hypothyroidism
    • puffiness and edema around eyes and face
  13. myxedema coma
    results from perisistently low thyroid hormone levels
  14. somogyi phenomenon
    • occurs in type 1 DM
    • normal/elevated blood sugars at bedtime, and then hypoglycemic about 2am-3am
    • treat with smaller predinner dose or increasing bedtime snack
  15. trousseaus sign
    • hypocalcemia
    • carpal spasm can be elicited by compressing the brachial artery with a blood pressure cuff for 3 min
  16. addisons disease S&S
    • lethartgy, fatigue, muscle weakness
    • gastrointestinal disturbances
    • weight loss, fever
    • menstrual changes, impotence in men
    • hypoglycemia, hyponatremia
    • hyperkalemia, hypercalcemia
    • postural hypotension
    • bronzed skin
  17. cushings disease S&S
    • gernalized muscle weakness, and wasting
    • moonface and buffalo hump
    • truncal obesity with thin extremities
    • supraclvicular fat pads and weight gain
    • hirsutism
    • hyperglycemia, hypernatremia
    • hypokalemia, hypocalcemia
    • hypertension
    • fragile skin that bruises easily
    • reddish purple striae on abd and upper thighs
  18. Conns syndrome
    • primary hyperaldosteronism
    • hypersecretion of mineralcorticoids (aldosterone) from adrenal cortex
  19. pheochromocytoma
    • catecholamine-producing tumor usually in adrenal medulla
    • typically benign
    • excessive epinephrine and norepinephrine secreted
    • associated with having htn
    • keep diet free from stimulants
  20. hypothyroidism S&S
    • lethargy and fatigue
    • weakness, muscle aches, paresthesias
    • intolerance to cold
    • weight gain
    • dry skin and hair and loss of hair
    • bradycardia
    • constipation
    • myxedema
    • forgetfulness and loss of memory
    • enlarged heart and CHF
    • possible goiter
  21. thyroid storm S&S
    • elevated temp
    • tachycardia
    • systolic htn
    • N,V, diarrhea
    • agitation, tremors, anxiety
    • irritability, restlessness, confusion and seizures
    • delirium and coma
  22. signs for tetany
    • cardiac dysrhythmias
    • carpopedal spasm
    • dysphagia
    • muscle and abd cramps
    • numbness and tingling of face and extremities
    • positive chvostek and trousseau
    • photophobia
    • bronchospasm, laryngospasm (wheezing and dyspnea)
    • seizures
  23. hypoparathyroidism S&S
    • hypocalcemia, hyperphosphatemia
    • numbness and tingling in face
    • muscle cramps and cramps in abd or extremities
    • positive trousseaus or chvosteks sign
    • signs of tetany
    • hypotension
    • anxiety, irritability and dression
  24. hyperparathyroidism S&S
    • hypercalcemia, hypophosphatemia
    • fatigue, muscle weakness
    • skeletal pain and tenderness
    • bone deformities, pathological fractures
    • anorexia, N, V, epigastric pain
    • weight loss
    • constipation
    • htn
    • cardiac dysrthmias
    • renal stones
  25. oral hypoglycemic meds
    type 2 DM
  26. insulin lipodystrophy
    • loss of subq fat
    • development of fibrous fatty masses at injection site
    • prevent by rotating site
  27. hypoglycemia S&S
    • hunger
