Lab Levels:
Low TSH
High T3 and T4

Answer 19

thyroid crisis

Question 20

Eliminate excess thyroid hormone
Minimize symptoms and long term consequences
Must individualize
Treat the cause or
the symptoms of the disease

Answer 20

goals for treating hyperthyroidism

Question 21

Surgery –actually take out part of the thyroid

Antithyroid medication
PTU, Methimazole
Radioactive Iodine (RAI)
Iodide 131

Answer 21

treatment for hyperthyroidism

Question 22

Impede the formation
Lower thyroid levels
Lower/normalize metabolic rate
May be used in preparation for thyroidectomy or radioactive iodine therapy
Risk of agranulocytosis (monitor CBC/instruct on s/s infection)
May alter response to warfarin or digoxin
Monitor of signs of worsening hyperthyroidism
or development of hypothyroidism
Administer at the same time of day in relation to meals (meals may affect absorption)

Answer 22

methimazole (antithyroid med, used to treat hyperthyroidism)

Question 23

PO med
Administer at the same time each day in relation to meals- may meals
May be used in preparation for thyroidectomy or radioactive iodine therapy in hyperthyroidism
Agranulocytosis is the most serious complication of antithyroid drug therapy (Monitor CBC)
Teach to monitor/report s/s of infection.
Monitor for continued/worsening signs of hyperthyroid
Monitor for development of hypothyroid
Granulocytes are type of WBC that fights infection. Can cause deficiency of these cells.

Answer 23

PTU or propylthiouracil, antithyroid med, used to treat hyperthyroidism

Question 24

Action: Antithyroid
Destroys thyroid producing cells
Dosage dependent Indications:
Hyperthyroidism and thyroid cancer
Thyroid function studies

Answer 24

radioactive iodine

Question 25

Hypothyroidism will be put on appropriate medication

Answer 25

adverse/side effects of radioactive iodine

Question 26
