Thyroid primary dysfunction Right Ans - Located at the thyroid gland
Thyroid secondary dysfunction Right Ans - Located at the pituitary gland
Thyroid tertiary dysfunction Right Ans - Located at the hypothalamus
TSH Right Ans - thyroid stimulating hormone; stimulates uptake & storage
of iodine by thyroid cells & release of T3 + T4
T3 Right Ans - thyroid hormone; short half-life; more potent; associated w/
graves disease
T4 Right Ans - thyroid hormone; longer half-life
TRH Right Ans - thyrotropin releasing hormone; stimulates thyrotropin
cells in anterior pituitary to release TSH
Calcitonin Right Ans - secreted by thyroid gland in response to high plasma
calcium levels
Thyroid: diagnostic tests Right Ans - TSH, T3, T4, inverted TSH in response
to T3/T4 levels, ultrasound, CT, MRI, thyroid scan(radioactive iodine
reuptake)
Thyroidectomy Right Ans - tx for thyroid cancer; modified or radial neck
dissection; radioactive iodine to minimize tumors
Thyroidectomy: PreOp Right Ans - minimize stress/anxiety; no
caffeine/stimulants; low-iodine diet; avoid salt, seafood, dairy, eggs, soy,
chocolate
Thyroidectomy: PostOp Right Ans - risk for infection, bleeding, airway,
pain management, potential for hypoglycemia, HOB raised > 30, keep neck in
neutral position
, Hypothyroid Right Ans - lack of T3/T4; increase in TSH
Hashimoto's Right Ans - primary hypothyroidism; autoimmune attacks the
thyroid causing decrease in T4 & increase in TSH as compensation; 95% of
hypothyroidism
Hypothyroidism: Medications Right Ans - Levothyroxine (Synthroid)
Levothyroxine: Nursing Considerations Right Ans - take on empty stomach;
monitor TSH frequently; do not stop taking or change dosage; fiber, calcium,
iron, antacid supplements interfere w/ absorption; monitor for irritability,
tachycardia, palpitations, heat intolerance & rapid weight loss
hypothyroid complications Right Ans - myxedema coma; decompensated
hypothyroidism
Myxedema coma s/s Right Ans - decrease in mental status; hypothermia,
bradycardia, acute coronary syndrome, hypoventilation/resp. (risk for
respiratory acidosis); failure, shock, hypoglycemia, death (high mortality)
Myxedema coma: cases Right Ans - sepsis; cold exposure; surgery; burns;
trauma; medication noncompliance
Myxedema coma: treatments Right Ans - maintain airway; administer
levothyroxine & hydrocortisone; dextrose for hypoglycemia; treating
symptoms (atropine - bradycardia; oxygen/pressured therapy -
hypoventilation)
Hyperthyroid s/s Right Ans - fine brittle hair; hair loss; bulging eyes;
sweating; goiter; enlarged liver; arrhythmia, N/V/D, increased appetite;
unexplained weight loss, loss of libido, amenorrhea, irritability, hyperactivity;
hyperglycemia; intolerance to heat; low cholesterol
Goiter Right Ans - increase in size of gland from increased demand; can
become toxic; caused from low iodine; over/underproduction of thyroid
hormone; may affect airway r/t tracheal compression; treat the cause
