Quizplus · Accepted Answer

Beta-adrenergic blockers (atenolol, metoprolol, and propranolol) are used to relieve some of the symptoms of thyrotoxicosis (thyroid storm), a complication of hyperthyroidism in which excessive thyroid hormones are released into the circulation. Beta blockers block the effects of the sympathetic nervous system and treat symptoms such as tachycardia, hypertension, irritability, tremors, and nervousness in hyperthyroidism. (Option A) Atenolol is not iodine based. Iodine is used to treat thyrotoxicosis or to prepare the client for a thyroidectomy. In large doses, iodine quickly blocks the release of T4 and T3 from the gland within hours. In addition, iodine decreases thyroid gland vascularity and is helpful when preparing the client for a thyroidectomy. (Option C) Atenolol does not contain radioactive iodine, the primary treatment for hyperthyroidism. It damages or destroys the thyroid tissue, therefore limiting thyroid secretion and eventually making the client hypothyroid. (Option D) Propylthiouracil and methimazole (Tapazole) are first-line antithyroid drugs used to inhibit thyroid hormone synthesis. Educational objective: Beta-adrenergic blockers (atenolol, metoprolol, and propranolol) are given to relieve some of the symptoms of thyrotoxicosis. They block the effects of the sympathetic nervous system and treat symptoms such as tachycardia, hypertension, irritability, tremors, and nervousness in hyperthyroidism.
