Question 1

Which medication is used to treat hyperthyroidism?&#10;A) Levothyroxine (Synthroid)&#10;B) Liotrix (Thyrolar)&#10;C) Propylthiouracil (Propacil)&#10;D) Liothyronine (Cytomel)

Accepted Answer

Propylthiouracil is an antithyroid agent used in the treatment of hyperthyroidism.Levothyroxine,liotrix,and liothyronine are used to treat hypothyroidism.

Question 2

Which medication is used in the treatment of hypothyroidism?&#10;A) Levothyroxine (Synthroid)&#10;B) Radioactive iodine&#10;C) Propylthiouracil (Propacil)&#10;D) Methimazole (Tapazole)

Accepted Answer

Levothyroxine (T₄)is one of the two primary hormones secreted by the thyroid gland.This hormone is partially metabolized to liothyronine (T₃),so therapy with levothyroxine (Synthroid)replaces both hormones.Levothyroxine is considered the drug of choice for hormone replacement in hypothyroidism.Radioactive iodine,propylthiouracil,and methimazole are used to treat hyperthyroidism.

Question 3

What is characteristic of antithyroid drugs that act on the thyroid gland?&#10;A) They are a physiologic hormone replacement.&#10;B) They block synthesis of T3 and T4 in the thyroid gland.&#10;C) They destroy T3 and T4.&#10;D) Immediate improvement is observed.&#10;E) They may be used before subtotal thyroidectomy.

Accepted Answer

Antithyroid drugs act by blocking the synthesis of T₃ and T₄.They are prescribed long term for patients with hyperthyroidism and may be used for short-term treatment before subtotal thyroidectomy.Antithyroid drugs are not related to synthetic or physiologic hormone replacement.Antithyroid drugs act by blocking the synthesis of,not destroying,T₃ and T₄.There is a latency period of a few days to 3 weeks before symptoms improve.

Question 4

Which nursing diagnosis may be identified for a patient with hyperthyroidism?&#10;A) Imbalanced nutrition: more than body requirements&#10;B) Constipation&#10;C) Disturbed sleep pattern&#10;D) Ineffective airway clearance

Accepted Answer

Hyperthyroidism is caused by an excess amount of thyroid hormones.Patients typically exhibit the following symptoms: rapid,bounding pulse (even during sleep); cardiac enlargement; palpitations; and dysrhythmias.Patients are nervous and easily agitated.Reflexes are hyperactive and the patient typically experiences insomnia.A nursing diagnosis of "Disturbed sleep pattern" would be a common problem.The patient with hyperthyroidism is likely to consume less than body requirements and is not likely to be constipated as a result of the disease.Ineffective airway clearance is not a common problem of patients with hyperthyroidism.

Question 5

A patient recently completed radiation treatment for throat cancer and presents to the health care provider's office with symptoms indicating possible hypothyroidism.Which symptom(s)would most likely be exhibited and/or reported?

A) Inability to sleep
B) Weight gain
C) Lethargy
D) Nervousness
E) Cold intolerance

Accepted Answer

Symptoms associated with hypothyroidism include weight gain,lethargy,and cold intolerance.Inability to sleep and nervousness are not symptoms associated with hypothyroidism.

Question 6

Medications ordered on a patient with hypothyroidism include liotrix and cholestyramine.The nurse administers the dose of liotrix at 08:00.When is the best time for the nurse to administer the cholestyramine?

A) 07:00
B) 08:00
C) 10:00
D) 12:00

Accepted Answer

To prevent binding of thyroid hormones by cholestyramine,administer doses at least 4 hours apart.

Question 7

A patient with myxedema complains to the nurse that he has a &#34;hangover&#34; the next morning after taking a pain medication at night.Which explanation by the nurse is the most accurate?&#10;A) &#34;You have increased sensitivity to the medicine because of your thyroid condition.&#34;&#10;B) &#34;Because you haven't been sleeping, you have increased fatigue and should increase the analgesic.&#34;&#10;C) &#34;You are not taking enough thyroid medication and you should increase the dosage.&#34;&#10;D) &#34;The pain medication is incompatible with your thyroid medication and you should find another analgesic to take.&#34;

Accepted Answer

Myxedema patients are sensitive to small doses of sedative hypnotics,anesthetics,and narcotics.Increasing the analgesic would only make the patient feel more lethargic in the morning.The patient should not change the dose of his thyroid medication without consulting his primary health care provider.Any pain medication is likely to have this effect because of the patient's thyroid condition.

Question 8

Which patient would be a candidate for radioactive iodine therapy?&#10;A) A 17-year-old woman with Graves' disease&#10;B) A 64-year-old woman with hypothyroidism&#10;C) A 46-year-old man with heart disease and thyroid cancer&#10;D) An 82-year-old man with myxedema crisis

Accepted Answer

Patients typically treated with radioactive iodine therapy are those who are beyond childbearing years,those with severe complicating diseases (e.g.,heart disease),those with recurrent hyperthyroidism after previous thyroid surgery,those who are poor surgical risks,and those who have unusually small thyroid glands.Women of childbearing age should not be treated with radioactive iodine.Hypothyroidism and myxedema are not treated with radioactive iodine.

Question 9

Which condition can occur if congenital hypothyroidism is not treated?&#10;A) Diabetes&#10;B) Impaired vision&#10;C) Periorbital edema&#10;D) Cretinism

Accepted Answer

Cretinism is a condition resulting from congenital hypothyroidism.Diabetes is not a complication of congenital hypothyroidism.Periorbital edema and impaired vision are complications of hyperthyroidism.

Question 10

Which clinical symptom(s)would the nurse observe in a patient with thyrotoxicosis?&#10;A) Decreased metabolic rate&#10;B) Decreased heart rate&#10;C) Decreased body temperature&#10;D) Muscle tremors&#10;E) Restlessness&#10;F) Anxiety&#10;G) Sweating

Accepted Answer

Thyrotoxicosis symptoms include muscle weakness and tremors,restlessness and nervousness,anxiety,sweating,increased metabolic rate,increased pulse rate (to perhaps 140 beats/min),and increased body temperature and a sensation of feeling too warm.

Question 11

The nurse is providing instruction to a patient recently prescribed a radioactive iodine isotope.Which is the correct action of this medication?&#10;A) Stimulates the synthesis of T3 and T4 hormones&#10;B) Increases the storage of thyroxine before thyroid surgery&#10;C) Destroys hyperactive thyroid tissue&#10;D) Replaces deficient thyroid hormone
