## Core Concept
Nephritic syndrome is characterized by inflammation of the glomeruli, leading to hematuria (blood in urine), proteinuria (less than 3.5 g/day), hypertension, and azotemia (elevated blood urea nitrogen). The key features are related to glomerular injury.

## Why the Correct Answer is Right
Option describes a condition not typically associated with nephritic syndrome. Nephritic syndrome primarily involves inflammation of the glomeruli, presenting with hematuria, mild proteinuria, hypertension, and renal insufficiency. Massive proteinuria (>3.5 g/day) is more characteristic of nephrotic syndrome.

## Why Each Wrong Option is Incorrect
* **Option A:** Hematuria is a hallmark of nephritic syndrome due to glomerular damage.
* **Option B:** Hypertension is commonly seen in nephritic syndrome as a result of renal involvement and fluid retention.
* **Option C:** Azotemia (elevated serum creatinine) occurs due to the kidneys' reduced ability to filter waste.

## Clinical Pearl / High-Yield Fact
A key distinction in renal pathology is that **nephritic syndrome** typically presents with **hematuria**, **mild proteinuria**, and **hypertension**, whereas **nephrotic syndrome** is characterized by **massive proteinuria (>3.5 g/day)**, **hypoalbuminemia**, and **edema**. Remembering this distinction can help in identifying the correct diagnosis and management plan.

**Correct Answer: . Massive proteinuria**
