Understanding Acute Kidney Injury: Nclex Questions Acute Kidney Injury
Acute kidney injury (AKI), formerly known as acute renal failure, is a sudden loss of kidney function. It can range from mild to severe and can be caused by a variety of factors, including dehydration, sepsis, and certain medications. AKI can lead to a buildup of waste products in the blood, which can be life-threatening if not treated promptly.
Pathophysiology of Acute Kidney Injury
The pathophysiology of AKI is complex and involves a number of different mechanisms. In general, AKI occurs when the kidneys are unable to filter waste products from the blood. This can be caused by a decrease in blood flow to the kidneys, damage to the kidney cells, or obstruction of the urinary tract.
- Decreased blood flow to the kidneyscan occur due to a number of factors, including dehydration, sepsis, and heart failure. When blood flow to the kidneys is reduced, the kidneys are unable to filter waste products from the blood.
- Damage to the kidney cellscan occur due to a number of factors, including toxins, infections, and certain medications. When kidney cells are damaged, they are unable to filter waste products from the blood.
- Obstruction of the urinary tractcan occur due to a number of factors, including kidney stones, tumors, and blood clots. When the urinary tract is obstructed, urine is unable to flow out of the kidneys, which can lead to a buildup of waste products in the blood.
Stages of Acute Kidney Injury
AKI is typically classified into three stages: mild, moderate, and severe. The stage of AKI is determined by the level of creatinine in the blood. Creatinine is a waste product that is produced by the muscles. When the kidneys are unable to filter creatinine from the blood, the level of creatinine in the blood will increase.
- Mild AKIis defined as a creatinine level of 1.5 to 1.9 times the upper limit of normal.
- Moderate AKIis defined as a creatinine level of 2.0 to 2.9 times the upper limit of normal.
- Severe AKIis defined as a creatinine level of 3.0 times the upper limit of normal or greater.
Clinical Manifestations of Acute Kidney Injury
Acute kidney injury (AKI) is a sudden decline in kidney function. It can be caused by a variety of factors, including sepsis, dehydration, and certain medications. AKI can range in severity from mild to severe, and it can lead to a number of complications, including fluid overload, electrolyte imbalances, and death.
The clinical manifestations of AKI can vary depending on the severity of the injury. Mild AKI may cause few symptoms, while severe AKI can lead to a number of serious complications. The most common symptoms of AKI include:
- Decreased urine output

Fluid and Electrolyte Management in Acute Kidney Injury
Fluid and electrolyte management is a crucial aspect of managing acute kidney injury (AKI). It involves maintaining fluid and electrolyte balance, preventing fluid overload, and correcting electrolyte abnormalities.
The goal of fluid management is to maintain adequate hydration while avoiding fluid overload, which can exacerbate AKI. Fluids are typically administered intravenously, and the type and amount of fluid used depend on the patient’s individual needs.
Types of Fluids Used in AKI
- Isotonic fluids, such as normal saline (0.9% sodium chloride) and lactated Ringer’s solution, are used to maintain fluid balance and electrolyte levels.
- Hypotonic fluids, such as 0.45% sodium chloride, are used to correct hypernatremia.
- Hypertonic fluids, such as 3% sodium chloride, are used to correct hyponatremia.
Electrolyte Management in AKI
Electrolyte abnormalities are common in AKI and can lead to serious complications. The nurse plays a vital role in monitoring and managing electrolyte balance.
