A patient with hyperthyroidism is to receive radioactive iodine therapy. What information should the nurse include in the patient teaching plan?

Correct Answer: A

Rationale: The correct answer is A. The rationale is that radioactive iodine therapy can harm a developing fetus, so patients should avoid close contact with pregnant women for one week. Choice B is incorrect as iodine supplements can interfere with the therapy. Choice C is incorrect as fluid intake should not be restricted unless specifically advised by the healthcare provider. Choice D is incorrect as there is no need to use disposable utensils for all meals.

Correct Answer: B

Rationale: The correct answer is B: Limit foods high in protein. Levodopa competes with amino acids for absorption in the small intestine, so consuming high-protein foods can reduce its effectiveness. Limiting protein intake can help maximize the absorption and efficacy of levodopa. Increasing vitamin C (option A) is not directly related to levodopa metabolism. Avoiding fiber (option C) is not necessary for levodopa therapy. Increasing sodium intake (option D) is not indicated for levodopa treatment in Parkinson's disease.

Correct Answer: D

Rationale: The correct answer is D because stopping warfarin one week before surgery reduces the risk of excessive bleeding during the procedure. Warfarin's anticoagulant effect can persist for several days, so stopping it earlier allows time for its effects to diminish. Choice A is incorrect because continuing warfarin until the day of surgery increases bleeding risk. Choice B is incorrect as stopping warfarin only three days before surgery may not provide enough time for the anticoagulant effect to wear off. Choice C is incorrect as aspirin is not a suitable substitute for warfarin in most cases.

Correct Answer: B

Rationale: The correct answer is B: To reduce nitrogenous waste. In renal failure, the kidneys cannot effectively filter waste products like urea and creatinine, leading to their accumulation in the blood. A low-protein diet reduces the production of these nitrogenous wastes, lessening the burden on the kidneys. A low-protein diet does not directly prevent fluid overload (A), maintain electrolyte balance (C), or prevent hyperglycemia (D) in renal failure. These functions are typically managed through other dietary modifications and treatments specific to each condition.

Correct Answer: B

Rationale: The correct answer is B: Relieve bronchospasm. Short-acting beta2-agonists (SABAs) like albuterol act by stimulating beta2 receptors in the airway smooth muscle, leading to bronchodilation and relieving bronchospasm. This helps to quickly open up the airways during an acute asthma exacerbation. Choice A is incorrect because SABAs do not directly reduce inflammation. Choice C is incorrect as SABAs do not affect respiratory secretions. Choice D is incorrect as SABAs do not suppress cough but rather target bronchospasm.
