A client with benign prostatic hyperplasia receives a new prescription of tamsulosin. Which intervention should the nurse perform to monitor for an adverse reaction?

Choice A reason: Administering levothyroxine at bedtime is not a correct statement, as it may interfere with sleep quality and hormone absorption. Levothyroxine is a synthetic thyroid hormone that replaces or supplements low levels of natural thyroid hormone in hypothyroidism. Levothyroxine should be taken in the morning, at least 30 minutes before breakfast, to avoid insomnia and ensure optimal absorption.

Choice B reason: Consuming foods that are high in iodine is not a correct statement, as it may affect thyroid function and hormone levels. Iodine is an essential element that is needed for thyroid hormone synthesis. However, too much or too little iodine can cause thyroid disorders, such as goiter or hyperthyroidism. Levothyroxine does not require additional iodine intake, and clients should follow a balanced diet.

Choice C reason: Avoiding the use of iron supplements is a correct statement, but it is not specific to levothyroxine. Iron supplements can interfere with many medications, including levothyroxine, by reducing their absorption and efficacy. Iron supplements should be taken at least 4 hours before or after levothyroxine or other medications.

Choice D reason: Taking medication on an empty stomach is a correct statement that indicates effective education. Levothyroxine should be taken on an empty stomach, preferably in the morning, to avoid food-drug interactions and enhance absorption. Food, especially those high in fiber or calcium, can decrease levothyroxine absorption and effectiveness.

Choice C reason: Acetylcysteine is a mucolytic agent that breaks down mucus and makes it easier to cough up or suction out. This helps to clear the airways and improve oxygenation. The nurse should expect to see increased sputum production after administering acetylcysteine and provide frequent suctioning as needed.

Choice A reason: Bronchodilation and wheezing are not therapeutic responses of acetylcysteine, but rather possible adverse effects. Acetylcysteine can cause bronchospasm or bronchoconstriction in some clients, especially those with asthma or chronic obstructive pulmonary disease (COPD). The nurse should monitor the client's breath sounds and oxygen saturation and report any signs of respiratory distress.

Choice B reason: Unpleasant smell when using the medication is not a therapeutic response of acetylcysteine, but rather a common side effect. Acetylcysteine has a rotten egg odor that can be unpleasant for both the client and the nurse. The nurse can minimize this by using a mouthwash or a flavored lozenge before and after administering acetylcysteine.

Choice D reason: Hypotension is not a therapeutic response of acetylcysteine, but rather a rare but serious adverse effect. Acetylcysteine can cause vasodilation or hypovolemia in some clients, leading to low blood pressure and shock. The nurse should monitor the client's vital signs and report any signs of hypotension.
