Renal Alterations Flashcards
Mean Arterial Pressure
Amount of pressure needed to perfuse the kidneys.
Calculated off of the BP
What is the minimum MAP to maintain normal kidney function?
70mmHg
What is the normal range for MAP?
70-90mmHg
What does Glomerular Filtration Rate (GFR) do?
Facilitates adequate reabsorption and waste removal.
What is the normal GFR?
80-125 mL/min (180L/day)
What is the normal urine output?
0.5-1 mL/kg or 30-60mL/hr
Where do pre renal issues happen?
Before the kidney.
Where do intrarenal issues occur?
Inside the kidney.
Where do post renal issues occur?
After the kidney.
What are the normal Urine Diagnostics?
- Color
- Turbidity
- ph
- Specific Gravity
- Blood
- Bacteria
- BUN and Creatinine
- Ketones
What is normal urine color?
Amber-yellow
What is normal urine turbidity?
Clear
What is normal urine pH?
4.6-8.0
If urine pH is closer to 8, what does that indicate?
Alkalinity which means bacteria is present.
What is normal urine Specific Gravity?
1.0 - 1.02
Do we expect to see blood in normal urine?
Negative for males
Possibly positive for females due to menstruation
How is bacteria represented in normal urine?
As a Yes/No instead of a value
What do we do if bacteria is present in the urine?
Culture it
What is Specific Gravity?
The weight of urine.
When Specific Gravity is High, what does that mean?
Contains bacteria, glucose, protein
When Specific Gravity is low, what does that mean?
The urine is dilute (clear)
BUN goes hand in hand with what?
Creatinine goes hand in hand
What does BUN stand for?
Blood, Urea, Nitrogen
How do we collect BUN and Creatinine?
Through a blood sample
What is BUN and Creatinine used to evaluate?
Normal kidney function
What does BUN measure?
Measures Urea in the blood
Where is Urea made?
In the liver
What is the normal range of BUN?
10-20mg/dL
What is the critical value of BUN?
> 100
What are the two markers of renal function?
BUN and Creatinine
Creatinine measures what?
Waste products of creatine in the blood
What is the normal range for Creatinine?
0.5-1.1 mg/dL
What is Creatinine Clearance?
How much creatinine the kidneys produce in a 24 hr period.
