Acute Renal Failure
A client arrives at a clinic with with complains of asthenia, malaise, headache,
weight gain, and a decrease in urination. A tentative diagnosis of acute renal failure is
made. Explain the pathophysiology of acute renal failure. Include prerenal, intrarenal and
postrenal cause. Acute kidney failure occurs when the kidneys are no longer able to
filture waste products from your blood. Unfortunatley this leads to unbalanced levels
of waste accumilated in the blood making this a very serious problem. This condition
can be fatal and requires intensive treatment. Fortunately, however this may be reversible. 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. This condition occurs when direct damage to the kineys causes a sudden loss of kidney function. Acute tubular nerosis is a very common cause of Intrarenal renal failure, a condition in which the small filtering tubes in the kidney are injured. Other causes are complicated surgeries
ACUTE RENAL FAILURE 3 (cardiovascular or abdominal), severe burns, or extreme muscle ingury. Postrenal kidney failure occurs when an obstruction in the urinary track below the kidney causes waste to build up in the kidney. Blockage in the urinary tract may produce an obstruction in one or both kidneys. Overtime the build up may prevent the normal flow of the urine, leading to postrenal acute renal failure. Unfortunetly, very serious conditions follow for example kidney stones, enlarged prostate, blood clots in the ureters or urethra, cancer of the prostate, cervix or colon. Immediate treatment is required.
What diagnostic exams would be used to diagnose acute renal failure? How do these tests change as renal failure progresses through its three stages? Discuss compare and contrast the three stages. Some tests and diagnosis include urine output measurments, urine tests, blood tests, imaging tests(ultrasound and computerized tomography), and the most invasive a kidney biopsy. The primary health care provier will usually start with the least inavsive procedure and as the stages or severity changes to more serious and ...
