thyroid drugs and labs Flashcards
antithyroid agent
- methimazol (Tapazole)
- inhibits synthesis of thyroid hormones
- monitor thyroid function and hepatic function
thyroid supplement
levothyroxine (Levoxyl, Synthroid)
- synthetic thyroid hormone
- give on empty stomach, 30 min-1 hour prior to breakfast
- monitor thyroid function
indication of thyroid antibodies
-assist in diagnosis of Graves’ disease
interpretation of thyroid antibodies
-increased in chronic thyroiditis, Grave’s disease, pernicious anemia, rheumatoid arthritis
indication of thyroid hormones (T3 and T4)
- evaluate hypothyroidism or hyperthyroidism
- monitor response to therapy
interpretation of thyroid hormones (T3 and T4)
- increased in hyperthyroidism, thyrotoxicosis, excessive intake of iodine, hepatitis
- decreased in hypothyroidism
nursing implications for thyroid hormones (T3 and T4)
monitor for hyper/hypothyroidism
indication for thyroid stimulating hormone (TSH)
-diagnosis of hypo or hyperthyroidism
interpretation of thyroid stimulating hormone (TSH)
- increased in primary hypothyroidism, thyroid hormone resistance, or thyroiditis
- decreased in excessive thyroid hormone replacement, Grave’s disease, primary hyperthyroidism, secondary hypothyroidism
nursing implications for thyroid stimulating hormone (TSH)
-recognize cause of hypothyroidism by comparing TSH level with T4 level
indications for radioactive iodine (RAI) uptake test
- evaluate hyperthyroidism or hypothyroidism
- evaluate thyroiditis, goiter, or pituitary failure
- monitor response to therapy for thyroid disease
interpretation of radioactive iodine (RAI) uptake test
- abnormal findings in decreased iodine intake or increased iodine excretion, Grave’s disease, iodine-deficient goiter
- increased uptake in hyperthyroidism
- decreased uptake in hypothyroidism
