1. Which of the following describes the primary pathophysiology of Nephrotic Syndrome?
A. Inflammatory injury to the glomeruli leading to hematuria and HTN
B. Obstruction of the renal pelvis by calculi leading to hydronephrosis
C. Increased glomerular permeability to plasma proteins resulting in massive proteinuria
D. Ascending infection of the urinary tract affecting the renal parenchyma
Answer: C
Conceptual Explanation: Nephrotic syndrome is characterized by massive proteinuria
(>3.5g/day) due to podocyte injury and increased glomerular basement membrane
permeability.
2. A patient presents with polyuria and a serum sodium of 155 mEq/L. The urine osmolality
remains low even after water deprivation. Which condition is most likely?
A. SIADH
,B. Psychogenic Polydipsia
C. Hyperaldosteronism
D. Diabetes Insipidus
Answer: D
Conceptual Explanation: Diabetes Insipidus (DI) is characterized by the inability to
concentrate urine due to a lack of ADH or renal resistance to ADH, leading to
hypernatremia and low urine osmolality.
3. In the pathogenesis of Type 1 Diabetes Mellitus, what is the primary cause of insulin
deficiency?
A. Insulin resistance in peripheral tissues
B. Amyloid deposition in the Islets of Langerhans
C. Excessive secretion of glucagon by alpha cells
D. T-cell mediated autoimmune destruction of pancreatic beta cells
Answer: D
Conceptual Explanation: Type 1 DM involves an autoimmune process where T-
lymphocytes destroy the insulin-producing beta cells in the pancreas.
4. Which clinical manifestation is a hallmark of Graves’ Disease due to thyroid-stimulating
immunoglobulins (TSI)?
A. Myxedema coma
, B. Weight gain and bradycardia
C. Exophthalmos
D. Hypocalcemia
Answer: C
Conceptual Explanation: Exophthalmos (bulging eyes) is specific to Graves’ disease
caused by TSI-induced inflammation of extraocular muscles and orbital fat.
5. What is the primary mechanism behind the development of prerenal Acute Kidney Injury
(AKI)?
A. Direct damage to the renal tubules
B. Decreased renal perfusion and reduced glomerular filtration pressure
C. Obstruction of the urinary outflow tract
D. Deposition of immune complexes in the glomerulus
Answer: B
Conceptual Explanation: Prerenal AKI is caused by factors that impair blood flow to the
kidney, such as hemorrhage, dehydration, or heart failure, without direct damage to the
renal tissue initially.
6. In Hyperosmolar Hyperglycemic Nonketotic Syndrome (HHNS), why is ketosis usually
absent?
A. The kidneys excrete all ketones efficiently
