Problem:
A 10-year-old child is brought to the local clinic after being bitten by a pit viper snake during a camping trip. The child presents with fang marks, local swelling, and severe pain at the bite site. Additionally, the child appears pale and lethargic, and has developed ecchymoses and petechiae throughout the body. Laboratory tests indicate a prolonged prothrombin time (PT), activated partial thromboplastin time (aPTT), and a decreased platelet count. What is the explanation for the abnormal coagulation tests and low platelet count? Group of answer choices Hemolytic uremic syndrome (HUS) Allergic reaction to snake venom Disseminated intravascular coagulation (DIC) Thrombotic thrombocytopenic purpura (TTP)
