<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:At 10 a.m. this morning, a semi-truck carrying radioactive waste toppled over due to a blown tire. One container was damaged, and a small amount of its contents leaked into the nearby river. You are a physician on the governments hazardous waste committee and must work to alleviate the towns worries and minimize the health hazards due to the radioactive leak. You decide to prescribe a prophylactic agent to minimize any retention of radioactive substances in the body. Which of the following do you prescribe?? A: Methylene blue, B: Vitamin C, C: Potassium iodide, D: EDTA, E: Succimer,  <response>: This is a question about prescribing the appropriate prophylactic agent to minimize retention of radioactive substances in the body after a radioactive waste spill. The key facts are that radioactive waste spilled into a nearby river, and we need to prescribe something to minimize retention of radioactive substances. Potassium iodide is often used to block uptake of radioactive iodine by the thyroid gland, as the stable iodine in the medication saturates the thyroid and prevents it from absorbing radioactive isotopes. Since radioactive waste likely contains radioactive iodine, potassium iodide would be the best choice to minimize retention. Methylene blue, vitamin C, EDTA, and succimer are not specifically used for radioactive exposure.C: Potassium iodide
