Test 4 Flashcards
Why are a BUN and Creatinine level important to kidney function?
An the ration of creatinine to BUN is used to determine if a patient is dehydrated (Normal ratio is 1:10. Other ratios such as 1:20 or 1:15 etc. can show dehydration). A high creatinine level can be an indicator of kidney damage as well
What is acute renal failure?
An abrupt reduction in the kidneys ability to function.
What is nephritis?
Inflammation of the kidneys that may involve the glomeruli, tubules or interstitial tissue surrounding them.
What is acute glomerulonephritis
Acute glomerulonephritis (GN) comprises a specific set of renal diseases in which an immunologic mechanism triggers inflammation and proliferation of glomerular tissue that can result in damage to the basement membrane, mesangium, or capillary endothelium
What is chronic renal failure?
A gradual decrees in the function of the kidneys over time.
What is Nephrosclerosis?
Nephrosclerosis, hardening of the walls of the small arteries and arterioles (small arteries that convey blood from arteries to the even smaller capillaries) of the kidney. This condition is caused by hypertension (high blood pressure).
What is creatinine clearance? How is it collected?
The amount of blood cleaned of creatinine by your kidneys is called the creatinine clearance. This is measured by a 24hr urine collection.
What is erythropoietin and what does it do?
Erythropoietin is a substance secreted by the kidneys that stimulates the production of red blood cells
What is creatinine?
Creatinine is produced by the breakdown of muscle and filtered out through the kidneys. Normal levels of creatinine are 0.5-1.1 and any elevation above this can be indicative of kidney disease or failure
What causes prerenal kidney failure?
Usually, prerenal acute renal failure is caused by sudden, severe interruptions to normal blood flow. Low blood volume or blood pressure can be caused by severe dehydration or severe bleeding such as that which results from a traumatic injury
What causes intrinsic kidney failure?
Results from an injury to the kidney. Can be caused by traumatic kidney injury or from drugs
What causes postrenal kidney failure?
Caused by blockage of urine that is produced by the kidneys from kidneys stones becoming lodged to tissue scarring in the ureters etc.
What does the glomerular filtration rate measure?
Measures how well your kidneys are cleaning your blood – taking out waste and extra water
What is hemodialysis?
Hemodialysis is used to filter out the blood of a patient with impaired renal functioning. Although dialysis is used to replace certain aspects of kidney function it cannot fully replicate the kidneys function and adjustments must be made in a persons diet and activity to compensate for such
What is peritoneal dialysis?
Peritoneal dialysis uses the peritoneum of the patients abdomen to filter out excess water and wastes. A catheter is placed in the patients peritoneum and a dialysis solution is infused in where it will absorb water and wastes to be drained at a later time.
What is continuous renal replacement therapy?
Is used for patients that are critically ill or are hypotensive and cannot afford any more fluid loss by gently removing wastes and fluids from the body
What can cause acute renal failure?
Acute tubular necrosis (ATN) 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
What can cause chronic renal failure?
Diabetes HTN Damage to kidney function Recurring kidney infections Inflammation in your kidneys’ filtration system Congenital kidney disease Obstruction of your urinary tract
What are some ways to treat acute renal failure?
Diuretics to treat fluid buildup
Potassium lowering drugs
Dialysis
What are some ways to treat chronic kidney failure?
Antianemics
Dialysis
What is active immunity?
Active immunity is a form of immunity that occurs from exposure to a disease organism where the body form antibodies to combat the disease
What are basophils?
Basophils are the rarest of all of the white blood cells and make up 1% or less of the circulating WBC. They are responsible for the inflammatory reaction during an immune response
