<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 3-year-old boy is brought to the emergency department by his mother. His mother reports that she found him playing under the sink yesterday. She was concerned because she keeps some poisons for pest control under the sink but did not believe that he came in contact with the poisons. However, this morning the boy awoke with abdominal pain and epistaxis, causing her to rush him to the emergency department.You obtain stat lab-work with the following results:WBC: 6,000microliter;Hgb: 11.2 gdL;Platelets: 200,000microliter;PTT: 35 seconds;INR: 6.5;Na: 140 mEqL;K: 4 mEqL;Cr: 0.7 mgdL.Which of the following is likely to be the most appropriate treatment?? A: Packed red blood cells transfusion, B: Dimercaptosuccinic acid DMSA, C: Vitamin K and fresh frozen plasma, D: Penicillamine, E: Protamine sulfate,  <response>: Based on the information provided in the question stem, this appears to be a case of accidental poisoning in a young child who got into pesticides stored under the sink. The lab results show a prolonged PTT, elevated INR and low hemoglobin, indicating coagulopathy and anemia. The poisons likely contained an anticoagulant rodenticide like warfarin, which inhibits vitamin K-dependent clotting factors. This explains the coagulopathy. The epistaxis nosebleed is likely due to the impaired clotting.Of the answer choices, vitamin K and fresh frozen plasma would be the most appropriate treatment. Vitamin K is the antidote for warfarinanticoagulant poisoning, and fresh frozen plasma provides clotting factors to help correct the coagulopathy in the short term while the vitamin K takes effect.The other choices are not relevant. Packed RBCs may help the anemia but do not address the coagulopathy. Penicillamine is used for heavy metal poisoning. DMSA is a chelating agent also used in heavy metal poisoning. Protamine sulfate reverses heparin, not warfarin.C: Vitamin K and fresh frozen plasma
