What are some s/s of hypothyroidism?
Non pitting edema
Slowed metabolism
Cold intolerance
Weight gain + decrease in appetite
Dry and brittle hair
Dry skin
V/s: low rr, hr, and bp
What micronutrient is essential for thyroid hormone production?
Iodine
What is it called when hypothyroidism become life threatening? S/s? Nursing
interventions?
- myxedema coma; occurs as a result of untreated, or poorly managed
hypothyroidism, may occur with acute illness, injury, surgery, chemo, change
in thyroid replacement, or use of sedatives
,- s/s: respiratory failure (hypoxia and carbon dioxide retention), low bp,
hypothermia, bradycardia, dysrhythmia, hyponatremia, hypoglycemia, coma,
facial edema, goiter, cold extremities, peripheral edema, constipation
- nursing interventions: admin o2, replace fluids and electrolytes, admin
thyroid replacement iv, ecg monitoring, keep patient warm, iv hydrocortisone
is also often given to prevent adverse effect of adrenal crisis
What is cretinism? What causes it? Tx?
Condition of congenital hypothyroidism in children that results in impaired
cognitive function, stunted growth, and poor work performance and behavior
The thyroid gland is either congenitally absent or imperfectly developed
(because of iodine deficiency)
Thyroid replacement therapy
What is hashimoto's thyroiditis? Dx?
- def: autoimmune destruction of thyroid gland
- dx: blood test for antithyroid antibodies
, What is the difference in thyroid hormones between primary and
secondary/tertiary hypothyroidism
- primary: tsh is high, t3 and t4 are low
- secondary/tertiary: tsh is normal or low, t3 and t4 are low
What are the thyroid replacement medications and what are their indications?
- levothyroxine (first line of treatment for hypothyroidism in patients),
liothyronine, liotrix
- all of these meds should be taken first thing in the morning on an empty
stomach, 30 minutes before breakfast
What is hyperthyroidism? S/s?
- increased t3 and t4 hormones which increases the metabolic rate
- s/s: tachycardia, htn, heat intolerance, weight loss even with increased caloric
consumption, insomnia and fatigue, hair loss, oligomenorrhea or amenorrhea,
anxiety/nervousness, thyroid bruit, increased gi motility
What autoimmune disease is a type of hyperthyroidism? S/s?
Graves disease; body makes antibodies against either tsh or against certain
cells in the thyroid
