MEDSURG II ENDOCRINE CORE MAIN QUESTIONS
AND ANSWERS SURE A+
✔✔what is the worst case for hyperthyroidism vs hypothyroidism - ✔✔hyper:
cardiovascular collapse (like addisonian crisis)
hypo: myxedema coma
✔✔what do we need to make thyroid hormones? what happens if we don't have it? -
✔✔iodine
goiter!
-swelling of thyroid in hyper or hypothyroidism bc cannot make T3/T4= metabolism
messed up
hyper: Gland making more and bigger automatically
hypo: gland getting bigger bc of high TSH, but cannot make T3/T4 bc no iodine, so just
big
✔✔why are we concerned about goiter? - ✔✔compresses airway
✔✔if T3 and T4 are high, but TSH and TRH are low, what type of disease is it?
what about if all are high?
TSH and T3/T4 high, but TRH low? - ✔✔primary
tertiary
secondary
✔✔what is hyperthyroidism called?
, what type of condition is it? - ✔✔grave's disease
autoimmune- trick to attack gland but instead just stimulate to secrete more, so huge
amounts of T4
-TSH and TRH shut off
✔✔what is thyrotoxic crisis/thyroid storm? - ✔✔excessive hormone amounts cause
catecholamine effect= epi and norepi= turns on SNS!! so get HTN and Tachycardia
✔✔s/s of hyperthyroidism - ✔✔hypermetabolic state
-tachy, jittery, 4+ pulses, HTN, weight loss, hyperthermia, restless, heat intolerance, etc
✔✔diagnoses related to hyperthyroid - ✔✔activity intolerance from fatigue and heat
intolernace
imbalanced nutritkon bc hypermetabolism and inadequate food intake
✔✔what is a temporary drug used to relieve hyperthyroid s/s? - ✔✔beta blockers
drug to block thyroid
✔✔meds used for hyperthyroid for:
1. antithyroid
2. to protect heart - ✔✔1. PTU, methimazole
2. BBs
✔✔why would we give a patient iodine?
caution? - ✔✔to make T3/T4
bolus can cause thyroid to shut off
give before surgery bc goiter vascular, so this makes it smaller!!
✔✔what is radioactive iodine therapy? - ✔✔use radioactive iodine to kill gland, give lols
and other as gland dying
then once dies, hypothyroid, so give synthyroid
✔✔patient teaching for hyperthyroid tx - ✔✔1. oral care with thyroiidits/parotiditis
-bc dry mouth
2. radiation precautions
3. symptoms of hypothyroid
✔✔why does someone with acute thyrotoxicosis get exophthalmos?
