Test 4 Flashcards

1
Q

Why are a BUN and Creatinine level important to kidney function?

A

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

Q

What is acute glomerulonephritis

A

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

Q

What is Nephrosclerosis?

A

Q

What is creatinine clearance? How is it collected?

A

The amount of blood cleaned of creatinine by your kidneys is called the creatinine clearance. This is measured by a 24hr urine collection.

Q

What is creatinine?

A

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

Q

What causes prerenal kidney failure?

A

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

Q

What is hemodialysis?

A

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

Q

What is peritoneal dialysis?

A

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.

Q

What is discoid lupus

A

Discoid lupus erythematosus is the most common type of chronic cutaneous lupus, an autoimmune skin condition on the lupus erythematosus spectrum of illnesses. It presents with red, inflamed, coin-shaped patches of skin with a scaling and crusty appearance, most often on the scalp, cheeks, and ears.
Can be treated with anti inflammatory medicines, steroids, or immunosuppressants

24
Q

What is an erythrocyte sedimentation rate?

A

Is used to test the inflammatory process in the body. The sed rate test measures the distance red blood cells fall in a test tube in one hour. The farther the red blood cells have descended, the greater the inflammatory response of your immune system

30
Q

What is passive immunity?

A

Introduction of antibodies from one person to another

Q

What is HIV/AIDS?

A

What is HIV/AIDS?

A

HIV is a virus that attacks the immune system and increases the patients susceptibility to infection

Q

What criteria must be met for HIV to be considered AIDS?

A

HIV affects t cells within the body with t cells normal levels being 500-1600 cells per mm of blood. When HIV develops into aids the t cell threshold falls below 200

A

Pernicious anemia occurs due to a lack of blood cells being produced due to a shortage of B12 vitamin in the body. It will present as paleness, weakness, SOB, dizziness, etc.

40
Q

What is aplastic anemia and what are the signs and symptoms? How would this be treated?
