A 5-year-old boy is brought to the physician with generalized edema that developed following a mild upper respiratory infection. His past medical history is unremarkable. The patient's blood pressure and heart rate are normal. Serum creatinine levels are normal. Urinalysis shows massive proteinuria with no hematuria. Further analysis reveals that the patient's urine protein consists principally
of albumin with only trace amounts of IgG and a2-macroglobulin. Which of the following pathologic changes is the most likely cause of this patient's urinary protein loss?
A. Thinning of the glomerular basement membrane
B. Glomerular crescent formation
C. Glomerular podocyte damage
D. Nodular glomerulosclerosis
E. Tubular necrosis and epithelial shedding

A 38-year-old man presents to the emergency department because he has been vomiting blood. Endoscopy reveals a bleeding duodenal ulcer. During his hospitalization, he develops prolonged oliguria. Renal biopsy shows epithelial necrosis of the tubules, tubulorrhexis, and intratubular casts. Which of the following is the most important complication during the recovery phase of this patient's
condition?
A. Metabolic acidosis
B. Hyperphosphatemia
C. Hypokalemia
D. Hypercalcemia
E. Volume overload

During the recovery phase (polyuric phase) of acute tubular necrosis, patients can become dehydrated and can develop severe hypokalemia due to high volume, hypotonic urine.

(رَبِّ اشْرَحْ لِي صَدْرِي وَيَسِّرْ لِي أَمْرِي وَاحْلُلْ عُقْدَةً مِّن لِّسَانِي يَفْقَهُوا قَوْلِي)

اللهم إني أعوذ بك من علم لا ينفع ومن قلب لا يخشع. اللهم أنفعني بما علمتني، وعلمني ما ينفعني، وزدني علما. اللهم إني أعوذ بك من الهمّ والحزن، وأعوذ بك من العجز والكسل. اللهمّ أخرجنا من ظلمات الجهل والوهم، وأكرمنا بأنوار المعرفة والفهم، وافتح علينا بمعرفة العلم، وحسّن أخلاقنا بالحلم، وسهّل لنا أبواب فضلك، وانشر علينا من خزائن رحمتك.

(وَإِذَا سَأَلَكَ عِبَادِى عَنِّى فَإِنِّى قَرِيبٌ أُجِيبُ دَعْوَةَ ٱلدَّاعِ إِذَا دَعَانِ)
