 CCRN Acute Renal Failure – Review

As a part of our CCRN Online Review Course, this article will focus primarily on Acute Renal Failure.  This article will cover in great detail the pathophysiology, signs and symptoms, causes, complications, and treatments for patients with acute renal failure.  For practice questions related to acute renal failure, visit our CCRN Review section for further details.

CCRN Acute Renal Failure Overview

Acute renal failure occurs when your kidneys suddenly lose the ability to eliminate excess salts, fluids, and waste materials from the blood.  This elimination is the core of your kidney’s main function.  Body fluids can rise to dangerous levels when the kidneys lose their filtering ability.  The condition will also cause electrolyte and waste material to accumulate in your body, which can also be life-threatening.

Acute renal failure is also known as acute kidney injury or acute kidney failure.  It’s most common for people who are already in the hospital.  It may develop rapidly over a few hours.  It can also develop over a few days to weeks.  People who are critically ill and need intensive care have the highest risk of developing acute kidney failure.

Acute renal failure can occur for many reasons.  Among the most common reasons are:

  • Acute tubular necrosis
  • Severe or sudden dehydration
  • Toxic kidney injury from poisons or certain medications
  • Autoimmune kidney diseases, such as acute nephritic syndrome and interstitial nephritis
  • Urinary tract obstruction

Reduced blood flow can damage your kidneys.  The following conditions can lead to decreased blood flow to your kidneys:

  • Low blood pressure
  • Burns
  • Dehydration
  • Hemorrhage
  • Injury
  • Septic shock
  • Serious illness
  • Surgery

Certain disorders can cause clotting within your kidney’s blood vessels, and this can lead to acute kidney failure. These conditions include:

  • Hemolytic uremic syndrome
  • Idiopathic thrombocytopenia purpura
  • Malignant hypertension
  • Transfusion reaction
  • Scleroderma
