What triad of symptoms is indicative of nephritic syndrome?

Nephritic syndrome is characterized by a specific set of clinical findings resulting from glomerular inflammation. The hallmark symptoms typically include the presence of hematuria (blood in the urine), oliguric state (reduced urine output), and hypertension (high blood pressure).

Hematuria occurs due to damage to the glomeruli, allowing red blood cells to enter the urine. Oliguria can be attributed to reduced kidney function resulting from inflammation, while hypertension typically arises from fluid retention and increased vascular resistance associated with glomerular damage.

The other options present symptoms that either do not align with nephritic syndrome or are more typical of nephrotic syndrome or other conditions. For example, nephrotic syndrome is characterized by significant proteinuria, hypoalbuminemia, and edema, which are not key features of nephritic syndrome.
