<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:An 8-year-old boy is brought to the pediatrician by his mother with nausea, vomiting, and decreased frequency of urination. He has acute lymphoblastic leukemia for which he received the 1st dose of chemotherapy 5 days ago. His leukocyte count was 60,000mm3 before starting chemotherapy. The vital signs include: pulse 110min, temperature 37.0C 98.6F, and blood pressure 10070 mm Hg. The physical examination shows bilateral pedal edema. Which of the following serum studies and urinalysis findings will be helpful in confirming the diagnosis of this condition? ? A: Hyperkalemia, hyperphosphatemia, hypocalcemia, and extremely elevated creatine kinase MM, B: Hyperkalemia, hyperphosphatemia, hypocalcemia, hyperuricemia, urine supernatant pink, and positive for heme, C: Hyperuricemia, hyperkalemia, hyperphosphatemia, lactic acidosis, and urate crystals in the urine, D: Hyperuricemia, hyperkalemia, hyperphosphatemia, and urinary monoclonal spike, E: Hyperuricemia, hyperkalemia, hyperphosphatemia, lactic acidosis, and oxalate crystals,  <response>: This is a clinical vignette describing an 8-year-old boy with acute lymphoblastic leukemia who recently started chemotherapy and now presents with nausea, vomiting, decreased urination, bilateral pedal edema, and other vital sign changes. The question asks which serum studies and urinalysis findings would help confirm the diagnosis. Based on the clinical history, the main diagnostic consideration is tumor lysis syndrome, which can occur after starting chemotherapy in a patient with a high tumor burden. Tumor lysis syndrome leads to rapid cell breakdown and release of intracellular contents into the bloodstream. This results in hyperuricemia, hyperkalemia, hyperphosphatemia and acute kidney injury. The urine may show urate crystals. So the correct answer should include these key lab abnormalities of tumor lysis syndrome.C: Hyperuricemia, hyperkalemia, hyperphosphatemia, lactic acidosis, and urate crystals in the urine
