Intrarenal kidney failure causes are actual damage to the nephrons and the functions of the tissues in the kidneys. This damaged could be grouped together under kidney disease or acute tubular necrosis. ATN could be reversible but it may take weeks or months before adequate perfusion returns (Ludwig, Mathews, Gregg 2012). Postrenal kidney failure is caused by obstruction to the urine flow or excretion. Common problems would tumors, benign prostatic hypertrophy (BPH), or kidney stones.
In objective data the nurse can actually see what is going on with the patient. Objective data can include: • Noticed swelling in arms and legs • Seeing the patient vomiting • Monitoring lab results • Mo... ... middle of paper ... ...failure is patient education. Knowing the signs will determine how well they will be able to recover. Long term care of renal failure may result in taking medications for life, being on long term dialysis and possible kidney transplant. Living a healthy lifestyle by staying away from foods that are bad for you and maintaining adequate fluids and exercise.
Explain the pathophysiology of acute renal failure. Include prerenal, intrarenal and postrenal causes. The pathophysiology of acute renal failure takes place when the kidney no longer works properly. Prerenal causes of acute kidney failure are a lack of prefusion to the kidney. The primary cause of prerenal is ischemia, or inadequate blood flow to the kidney.
Prerenal, intrarenal and postrenal are sub classification for acute renal failure. Prerenal is the most common form of kidney failure. Blood flow to the kidney that is reduce/interrupted may cause damage to the tissues and recue the ability of the kidney to function. This includes burns, loss of blood volume, heart failure, shock, long-term vomiting/diarrhea/bleeding, injury to the kidney, and certain types of surgery. Prerenal failure if identified early and treated correctly may be reversible.
Not getting the proper amount of fluids may cause an ambulance and lead to a prerenal ARF. The use of diuretics can flush out large amounts of fluids, also dehydrating the patient and causing an imbalance in fluid and electrolytes. Patients who have heart conditions take diuretics to prevent other problems and that puts them at a higher risk for prerenal problems. A few other risk factors may include hemorrhage, cardiac dysrhythmias, anaphylaxis, and embolism. Intrarenal/Intrinsic This acute renal failure occurs within the kidneys.
Prerenal kidney failure occurs suddently when a reduction in blood flow to the kidneys causes loss of kidney function. Prerenal renal failure is the most common type of acute renal failure. This complication is product of many diseases, conditions, and medications that decrease the normal amount of fluid and blood especially in the body. Some examples of these medications are ACE Inhibitors and NSAIDS, severe dehydration, and burns. Another type of kidney faiulre is Intrarenal.
1. Explain the pathoplysiology of acute renal failure. Including perenal,intraernal and posternal causes. Acute renal failure is when the kidneys have suddenly stopped working this disease disables the body’s mechanism of excreting waste products and maintaining fluid electrolyte balance. According to WebMD, the causes are characterized as a sudden decrease of blood flow to the kidneys, damage from some medications, poisons, or infections, a sudden blockage that stops urine from flowing out of the kidney.
However, in some cases an individual may develop acute renal failure. Its rapid development impairs the kidneys unless the underlying cause of the problem is found immediately and treated properly. When the cardiovascular system fails to perfuse the kidneys adequately with blood, the result is acute renal failure. In acute renal failure (ARF) the kidneys suddenly loses its ability to excrete wastes, concentrate urine, conserve electrolytes, and maintain fluid balance (Schrier, Wang, Poole & Mitra, 2004). The glomerulus, or the capillary network inside the Bowman’s capsule, is responsible for the entire filtrating system of our kidneys.
The basic function of a working kidney is to remove toxic waste from the bloodstream, balances body fluids and forms urine. (WebMd, 2013) When the kidney, which is an essential part of the human body fails and blood flow is compromised by electrolyte and acid base abnormalities this is Acute Renal Failure (ARF) also known as Acute Kidney Injury. There are three major causes of acute renal failure. First being Prerenal, which is primarily a severe drop in blood pressure and cessation of blood flowing to the kidneys caused by a traumatic injury or a severe illness. Secondly, another cause is Intrarenal which is the Middle stage of renal Failure, manifested by edema, toxins, drugs and decreased blood supply.
When we get sick such as running a fever, vomiting and diarrhea cause fluid loss. These can lead to Dehydration which can cause kidney not to filter correctly.. Even drug treatments with diuretics can cause fluid loss. . Intrarenal is due to the functional unit of the kidney having some type of damage done to it.
