d After thyroid surgery, the nurse suspects damage or removal of the parathyroid glands when the patient develops a. muscle weakness and weight loss b. hyperthermia and severe tachycardia c. hypertension and difficulty swallowing d. laryngospasms and tingling in the hands and feet a To control the side effects of corticosteriod therapy, the nurse teaches the patient who is taking corticosteroids to: a. increase calcium intake to 1500 mg/dL b. perform glucose monitoring for hypoglycemia c. obtain immunizations due to high risk of infections d. avoid abrupt position changes because of orthostatic hypotension AD c The nurse teaches the patient that the best time to take corticosteroids for replacement purposes is a. once a day at bed time b. every other day on awakening c. on arising and in the late afternoon d. at consistent intervals every 6-8 hours Hyperthyroidism This is a hyperactivity of the thyroid gland with sustained increase in synthesis and release of thyroid hormones Hyperthyroidism This occurs in woman more than men, with the highest frequency in persons 20-40 years old Grave's Disease What is the most common form of hyperthyroidism? Hyperthyroidism Since ________________ may be precipitated by iodinated contrast media used in CT scans and other radiological studies, those who are at risk should be monitored closely after iodinated contrast media exposure Thyrotoxicosis Hyperthyroidism This refers to the physiologic effects or clinical syndrome of hypermetabolism resulting from excess circulating levels of T4, T3, or both Subclinical Hyperthyroidism ________________ hyperthyroidism occurs when the patient has a serum TSH level below 0.4 mU/L but normal T4 and T3 levels Overt Hyperthyroidism _____________ hyperthyroidism is defined by low or undetectable TSH and elevated T4 and T3 levels Grave's Disease Hyperthyroidism This disease is an autoimmune disease of unknown etiology characterized by diffuse thyroid enlargement and excess thyroid hormone secretion. It accounts for 75% of the cases of hyperthyroidism Five Hyperthyroidism Women are ____ times more likely than men to develop Grave's disease AD Grave's Disease Hyperthyroidism -Insufficient iodine supply -Cigarette smoking -Infection -Stressful life events These all interact with genetic factors that can cause what disease? Grave's Disease Hyperthyroidism In ___________ disease, the patient develops antibodies to the TSH receptor. These antibodies attach to the receptors and stimulate the thyroid gland to release T3, T4, or both Metabolism Clinical Manifestations of Hyperthyroidism Hyperthyroidism directly increases ____________ and tissue sensitivity to stimulation by the sympathetic nervous system Goiter Clinical Manifestations of Hyperthyroidism Palpation of the thyroid gland in a patient with hyperthyroidism may reveal this, which is an enlarged thyroid gland Opthalmopathy Clinical Manifestations of Hyperthyroidism This is a common finding that is used to describe abnormal eye appearance or function Exophthalmos Clinical Manifestations of Hyperthyroidism This is a protrusion of the eyeballs from the orbits that is usually bilateral. This may result from increased fat deposits and fluid in the orbital tissues and muscles Acropachy Clinical Manifestations of Hyperthyroidism This term describes a clubbing of the fingers, and is known to occur with advanced stages of the disease Thyrotoxicosis Complications of Hyperthyroidism Acute ___________ is an acute, severe, and rare condition that occurs when excessive amounts of thyroid hormones are released into the circulation. Manifestations include tachycardia, heart failure, shock, hyperthermia, agitation, delerium, and abdominal pain TSH Diagnostic Studies of Hyperthyroidism One of the primary laboratory findings used to confirm hyperthyroidism is low or undetectable ______ levels thyroxine (T4) Diagnostic Studies of Hyperthyroidism One of the other primary laboratory findings used to confirm hyperthyroidism is elevated free ___________ levels 35-95% 2% Diagnostic Studies of Hyperthyroidism In the RAIU test, the patient with Grave's disease shows a diffuse, homogeneous uptake of ____ to ____ percent, whereas the patient with thyroiditis shows an uptake of less than _____ percent Hormones Hyperthyroidism Interprofessional Care The first-line antithyroid drugs are responsible for inhibiting the synthesis of thyroid _____________ Propylthiouracil Hyperthyroidism Interprofessional Care This drug is considered first-line therapy in thyrotoxicosis, since it also blocks the peripheral conversion of T4 to T3. It must be taken 3 times a day Iodine Hyperthyroidism Interprofessional Care _________ is used with other antithyroid drugs to prepare the patient for thyroidectomy or for treatment of thyrotoxicosis. Rapidly giving large doses of this inhibits synthesis of T3 and T4 and blocks the release of them into the circulation
