A nurse is explaining the pathophysiology of glomerulonephritis to a client. What is the primary underlying process that occurs in glomeruli leading to this condition?
Reduced blood flow to the kidneys
Increased glomerular filtration rate (GFR)
Inflammation and damage to the glomerular basement membrane
Excessive reabsorption of sodium
The Correct Answer is C
A) Incorrect. Glomerulonephritis is not primarily characterized by reduced blood flow to the kidneys.
B) Incorrect. Increased GFR is not the primary mechanism involved in the pathophysiology of glomerulonephritis.
C) Correct. Inflammation and damage to the glomerular basement membrane, often triggered by immune responses, are central to the pathophysiology of glomerulonephritis.

Correct Answer is B
Explanation
A) Incorrect. Reabsorption of water and electrolytes primarily occurs in the renal tubules, not the glomeruli.
B) Correct. The primary function of the glomeruli is to filter blood to form urine by removing waste products and excess substances.
C) Incorrect. Hormone secretion, including renin, is not a primary function of the glomeruli but may occur elsewhere in the kidney.
D) Incorrect. While the kidneys play a role in blood pressure regulation, this function involves other structures in addition to the glomeruli.
Correct Answer is C
Explanation
A) Incorrect. Glomerulonephritis primarily affects the glomeruli, not the renal tubules.
B) Incorrect. The renal pelvis is not the primary site of glomerulonephritis; it is a part of the renal collecting system.
C) Correct. Glomerulonephritis is an inflammatory condition that primarily affects the glomeruli, which are tiny structures in the kidneys responsible for filtering blood.
D) Incorrect. The renal medulla is not the primary site of glomerulonephritis; it is deeper within the kidney and not directly involved in this condition.
