Quiz: Chapter 31 – Thyroid and Anti-Thyroid Drugs Flashcards
- The nurse is reviewing adverse affects of anti-thyroid medications with that PT who’s been taking PTU. What adverse effects does the nurse include in the teaching? (Select all that apply.)
A) liver toxicity B) polyuria C) kidney damage D) bone marrow toxicity E) joint pain
A) liver toxicity, D) bone marrow toxicity, E) joint pain
- The nurse would suspect excessive thyroid replacement in a patient taking levothyroxine (Synthroid) when the patient is exhibiting which adverse effect?
A) depression
B) intolerance to cold
C) weight gain
D) irritability
D) irritability
– Irritability is a symptom of hyperthyroidism. The other choices are signs of hypothyroidism.
- Which patient statement demonstrates understanding of radioactive iodine (I-131) therapy?
A) I will have to isolate myself from my family for one week so as not to expose them to radiation
B) the struggle be taken up by the thyroid gland and destroy the cells to reduce my hyperthyroidism
C) this drug will help decrease my cold intolerance and weight gain
D) I will need to take this drug on a daily basis for at least one year
B) the drug will be taken up by the thyroid gland and destroy the cells to reduce my hyperthyroidism
– Radioactive iodine is an anti-thyroid medication that is administered orally for one or two doses only. It concentrates in the thyroid gland, enabling the radiation to destroy the hyperplastic cells.
- The nurses is teaching the PT taking an anti-thyroid medication to avoid foods high in iodine. Which food will the nurse advise the patient against?
A) milk
B) eggs
C) seafood
D) chicken
C) seafood
- Which statement by the PT demonstrates an understanding of discharge instructions on the use of levothyroxine (Synthroid)?
A) I will take this med in the morning so as not to interfere with sleep
B) I will double my dose if I gain more than 1 pound per day
C) I will stop the medication immediately if I lose more than 2 pounds in a week
D) I can expect to see release of my symptoms within one week
A) I will take this medication in the morning so as not to interfere with sleep
– Levothyroxine increases basal metabolism and thus wakefulness. PT’s should not double the dose or stop taking the medication abruptly. It may take up to four weeks for therapeutic response to occur.
- A PT receiving propylthiouracil (PTU) ask the nurse how this medication will help relieve his symptoms. Which is the nurses best response?
A) it inactivates any circulating thyroid hormone, that’s decreasing signs and symptoms of hyperthyroidism
B) it inhibits the formation of new thyroid hormone, thus gradually returning your metabolism to normal
C) it helps your thyroid gland use iodine and synthesize hormones better
D) it stimulates the pituitary gland to secrete thyroid-stimulating hormone (TSH), which inhibits the production of hormones by the thyroid gland
B) and inhibits the formation of new thyroid hormone, that’s gradually returning your metabolism to normal
Propylthiouracil is an anti-thyroid medication used to treat hyperthyroidism. It works when hitting the synthesis of new thyroid hormone. It is not an octave a present for loan.
- Patients taking leveothyroxine (Synthroid) and warfarin (Coumadin) concurrently should be monitored for which address affect?
A) cardiac arrhythmias
B) increased risk of bleeding
C) excessive weight loss
D) increased risk of deep vein thrombosis
B) increased risk of bleeding
– levothyroxine can compete with protein-binding sites of warfarin, allowing more boyfriend to be unbound or free, thus increasing effects of warfarin and risk of bleeding
- When assessing for potential toxicity to PTU, the nurse will monitor the patient for changes in which lab test?
A) CBC
B) BNP
C) serum electrolytes
D) renal function tests
A) CBC
– Was anti-thyroid medications, the nurse should monitor for possible toxic reactions such as agranulocytosis, pancytopenia, and life-threatening hepatitis. An abnormal CBC would indicate bone marrow dysfunction.
