A patient is admitted with Hematuria, Oliguria and Hypertension. The most likely diagnosis is?

Appeared in: WCL Staff Nurse - 2019

Explanation

  • The patient's symptoms—hematuria, oliguria, and hypertension—form the classic triad of acute nephritic syndrome.
  • Glomerulonephritis, an inflammation of the kidney's filters (glomeruli), is the most common cause of acute nephritic syndrome.
  • Inflammation damages the glomeruli, causing red blood cells to leak into the urine (hematuria), reducing the filtration rate (oliguria), and leading to fluid retention and high blood pressure (hypertension).
  • The presence of all three key symptoms makes glomerulonephritis the most likely diagnosis over the other options.

Why Other Options Were Wrong

  • Option A: Cushing's syndrome is an endocrine disorder caused by excess cortisol. While it can cause hypertension, its hallmark signs are central obesity, moon face, purple striae, and muscle weakness. Hematuria and oliguria are not primary features.
  • Option B: Nephrotic syndrome is primarily characterized by massive proteinuria (greater than 3.5 g/day), severe edema, hypoalbuminemia, and hyperlipidemia. While mild hematuria can occur, it is not the dominant feature, and hypertension is less common and severe than in nephritic syndrome.
  • Option D: A urinary tract infection (UTI) typically presents with symptoms of lower urinary tract irritation, such as dysuria (painful urination), frequency, and urgency. While hematuria can be present, significant hypertension and oliguria are not characteristic of a typical UTI.

Clinical Relevance
  • Nursing practice connection: Use the key finding related to Differential diagnosis of renal disorders based on clinical presentation to guide bedside assessment, documentation, and the next nursing action.
  • Nurses must be able to recognize the triad of hematuria, oliguria, and hypertension as a potential sign of acute glomerulonephritis, which requires prompt medical attention to prevent complications like acute kidney injury and hypertensive encephalopathy.
  • Key nursing interventions for a patient with acute glomerulonephritis include strict monitoring of blood pressure, maintaining an accurate fluid intake and output chart, daily weight measurement to assess fluid status, and enforcing dietary restrictions (sodium, fluid, and sometimes protein).
  • What if? If the patient's primary symptom was severe, generalized edema and frothy urine with minimal hematuria, the priority diagnosis would shift from glomerulonephritis (nephritic) to nephrotic syndrome, and management would focus more on managing the massive protein loss and severe edema.
How to Approach the Question
  • First, identify the key clinical findings presented in the question stem: hematuria, oliguria, and hypertension.
  • Recognize that this combination of symptoms forms a classic clinical triad.
  • Systematically evaluate each option to see which disease process best explains this specific triad.
  • Rule out Cushing's syndrome as it's primarily an endocrine disorder with a different set of hallmark signs.
  • Differentiate between nephritic syndrome (glomerulonephritis) and nephrotic syndrome. Recall that nephritic syndrome is characterized by inflammation and hematuria, while nephrotic syndrome is defined by massive proteinuria.
  • Eliminate UTI as it typically causes irritative voiding symptoms, not the systemic signs of oliguria and hypertension.
Concept Tested & Keywords
  • Concept Tested: Differential diagnosis of renal disorders based on clinical presentation.
  • Stem keywords: Hematuria, Oliguria, Hypertension
  • Lead-in keywords: most likely diagnosis
  • Clinical cues: The combination of hematuria, oliguria, and hypertension is a classic triad pointing towards acute nephritic syndrome.
