He also complains of nausea and abdominal pain. The child was in his usual state of health a week ago when they first notice swelling around his eyes. A few days later his legs started to swell. The boy was born at 39 weeks gestation via spontaneous vaginal delivery. He is up to date on all vaccines and is meeting all developmental milestones. Today, his blood pressure is 10460 mm Hg, the heart rate is 90min, the respiratory rate is 25min, and the temperature is 37.1C 98.8F. On examination, he has facial edema, abdominal shifting dullness, and bilateral leg edema up to the knees. Urine dipstick shows 4 protein and urinalysis shows fatty casts. Serum albumin is 2.2 gdL. Which of the following is the most likely etiology of this patient condition?? A: Minimal change disease, B: Acute glomerulonephritis, C: Congestive heart failure, D: Kwashiorkor, E: Protein-losing enteropathy,  <response>: This is a clinical vignette describing a 2-year-old boy with progressive swelling of the face and body, as well as nausea, abdominal pain and laboratory findings of proteinuria, fatty casts in the urine, and hypoalbuminemia. The key findings are:- Facial and generalized edema - Proteinuria and fatty casts suggesting nephrotic syndrome- Normal blood pressure - HypoalbuminemiaThis presentation is most consistent with nephrotic syndrome due to minimal change disease, which is the most common cause of nephrotic syndrome in children. Acute glomerulonephritis would present with hypertension, hematuria and renal insufficiency. Congestive heart failure is unlikely with normal blood pressure and no cardiac history. Kwashiorkor causes hypoalbuminemia but not significant edema or proteinuria. Protein-losing enteropathy can cause hypoalbuminemia and edema but not significant proteinuria.A: Minimal change disease
