hyperthyroidism Flashcards
thyroid gland
-produces hormones T3 T4 calcitonin
calcitonin/calcimere
DECREASES serum Ca by taking calcium out of the blood and pushing t back into the bone
S/S of hyperthroid/Graves disease
-nervous
-weight loss
-sweaty/hot
-exophthalmos(bulging eyes,excess fluid)
-attention span decrease
-appetite increase
-irritable
GI fast
BP increased
-Thyroid enlarged
-increased workload on heart
hyperthyroid diagnosis
- T3 T4 increased
- Thyroid scan/sonogram, fine needle aspiration/biopsy
- Pt must discontinue any iodine containing medication 1wk prior to scan
Hyerthyroid treatment: anti-thyroids
propylthiouracil(PTU), Methimazole (Tapazole)
- stops the thyroid from making thyroid hormone
- used pre-op to stun the thyroid
- want pt to become euthyroid(=normal)
hyperthyroid treatment iodine compounds:
potassium iodine(sski), strong iodine solution (lugol’s solution)
- decreases chance of bleeding
- decrease the size and vascularity of the gland
- give in milk,juice w/straw to avoid staining teeth
hyperthyroid treatment beta blockers
Propanol(Inderal)
- decreases myocardial contractility
- could decrease cardiac output
- decreses HR, BP
- decreases anxiety (blocks release of epi/norepi)
do u give beta blockers to asthmatics or diabetics?
Do not give beta blockers to asthmatics or diabetics/pt with COPD
-asthmatics can have a selective beta blocker
hyperthyroidism treatment:radioactive iodine
-1 dose of radioactive iodine
-decreases size and vascularity & size of thyroid
-oral liquid or tablet given (rule out pregnancy first)
-DESTROYS thyroid cells
-follow radioactive precautions
(stay away from babies 24hr
no kissing 24hr)
watch for thyroid storm
Thyroid storm(thyrotoxicosis,thyrotoxic crisis)
-hyperthyroism multiplied by 100 can lead to heart attack
could be rebound effect from post radioactive iodine
-thyroid storm is an EMERGENCY
-radioactive iodine is not only cause
-pt needs to be in ICU
-for hypocalcemia IV calcium at the bedside
hyperthyroidism treatment Surgery
Thyroidectomy(partial/complete)
post op:
- teach pt how to support neck
- place personal items close to them
- Positioning: elevate HOB to decrease edema and suture tension
- check for bleeding/back of neck/ look for bruising
- Nutrition(pre/post op) need more calories
- assess for laryngeal nerve damage by listening for hoarseness
- could lead to vocal cord paralysis, if there is paralysis of both cords airway obstruct will require immediate trach
- teach pt to report c/o pressure
- must be a trach set at bedside
- assess for hypocalcemia due to parathyroid removal s/s not sedated rrigid muscles, seizure
eye care in hyperthyroidism
- if pt can’t close eyes/ hypoallergenic tape may be used to prevent injury or irritation
- dark glasses for photosensitivity
- artificial tears to prevent drying of the eyes
- treatment does not correct any eye/vision problems
what will TSH level look like in hyperthyroidism
TSH will be low and TH will be high
