<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 62-year-old woman is hospitalized after a recent viral illness complicated by congestive heart failure. She has a past medical history of obesity and hypertension controlled on lisinopril but was otherwise healthy until she developed fatigue and edema after a recent viral illness. In the hospital, she is started on furosemide to manage her fluid status. On day 5 of her admission, the patients temperature is 100.0F 37.8C, blood pressure is 13688 mmHg, pulse is 90min, and respirations are 14min. The patient continues to have normal heart sounds, but with crackles bilaterally on lung auscultation. Edema is 3 up to the bilateral knees. On labs, her leukocyte count is now 13,000mm3, up from 9,000mm3 the day before. Differential shows that this includes 1,000 eosinophilsmm3. Creatinine is 1.7 mgdL from 1.0 mgdL the day before. Which of the following is most likely expected on urinary analysis?? A: Bacteria 100 CFUmL, B: Crystals, C: Leukocyte esterase positive, D: Nitrites positive, E: Red blood cell casts,  <response>: This is a clinical vignette about a 62-year-old woman hospitalized for congestive heart failure who develops a fever, leukocytosis with eosinophilia, and worsening renal function while on furosemide. The question asks which urinary analysis finding would be most expected in this scenario.The key findings in the vignette are the recent use of furosemide, a loop diuretic, along with the patients worsening renal function as evidenced by the increased creatinine. Furosemide can cause acute interstitial nephritis, which can present with fever, eosinophilia, and worsened renal function. Interstitial nephritis classically causes sterile pyuria, which would be detected as leukocyte esterase positive on urinalysis. Of the choices given, leukocyte esterase positive would be the most likely urinary analysis finding in this clinical scenario. Bacteria, crystals, nitrites, and RBC casts would not be expected.C: Leukocyte esterase positive
