    • -not curative
  24. what is main prpose for giving iodine
    • prep for thyroidectomy
    • tx of thyrotoxic crisi
    • used with antithyroid meds
    • DECREASE BLEEDING AFTER SURGERY
  25. fact about iodine
    • hyperthyroidism
    • drease vascularity of thyroid gland decreasing bleeding
  26. main reason for giving B adrenergenic blockers
    • hyperthyroidism
    • decreases SNS s/s
  27. B adrenergenic blockers
    propranolol for hyperthyroidism
  28. radioactive iodine uses
    • hyperthyroidism
    • destroy excess thyroid tissue
    • limit thyroid hormone secretion
  29. radioactive iodine effects
    up to 3 months so continue with other meds
  30. radioactive iodine contraindication
    rebound hypothyroidism
  31. hyperthyroidism nutrition facts
    • 4000-5000 calories per day
    • 6 full meals plus snacks
    • high carb high protein
    • avoid: fiber and caffine

    • -unresponsive to antithyroid drug
    • -large goiters w/ compression
    • -malignancy
    • not candidate for RAI
  34. thyroidectomy post op care
    • rom
    • support head manually
    • talking difficult for 3-4 days
    • hoarsness and edema
  35. thyroidectomy post op

    when to monitor
    best position
    every 2hrs for 24 hrs asses for hemmorage and compression

    semi fowlers position
  36. how to asses for signs of hemmorage after thyroidectomy
    inspect dressing
  37. how to asses for signs of compression after thyroidectomy
    • o2 sat
    • dyspnea
    • frq swallowing
    • sob
  38. after a thyroidectomy, how do you decrease tenion on suture lines
    • avoid flexion
    • elevate hob
  39. what levels to monitor after thyroidectomy
    calcium levels because remove parathyroid which decreases calcium
  40. how to check for tetany
    • muscle cramps or laryngeal stridor
    • trosseaus and chovstecks signs
    • monitor for 72 hours
