2. A patient with a history of heart failure has been diagnosed with hypothyroidism. The drug interaction with glycosides and thyroid replacement therapy will most likely require which change in therapy?

ANS:  B

If thyroid replacement therapy is started while receiving digoxin, a gradual increase in the glycoside will also be necessary to maintain adequate therapeutic activity. Decreasing the digoxin would put the patient at risk for cardiovascular complications. The two treatments can be coordinated. The thyroid medication does not need to be increased.

3. Which nursing diagnosis may be identified for a patient with hyperthyroidism?

ANS:  C

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.

4. The nurse is providing instruction to a patient recently prescribed a radioactive iodine isotope. Which is the correct action of this medication?

ANS:  C

The thyroid gland absorbs high concentrations of radioactive iodine, which destroys the hyperactive thyroid tissue with essentially no damage to other tissues in the body. Radioactive iodine does not stimulate hormone synthesis, increase hormone storage, or replace deficient hormones.
