Fill in the blanks for compensatory response to renal injury
- Decrease # nephrons
- Compensatory increase in size and function of remaining nephrons
- Glomerular and tubular lesions
- Loss of nephrons greater than compensatory capacity
- Progressive decrease in GFR
- Azotemia
- Uremic syndrome
What two major conditions make up over 60% of sources in kidney injury/failure?
Diabetes and high blood tension
Normal glomerular capillary pressure is maintained by afferent vaso(dilation/constriction) and efferent vaso(dilation/constriction)
Normal glomerular capillary pressure is maintained by afferent vasodilation and efferent vasoconstriction
What happens to GFR, vasodilatory prostaglandins and angiontension II with the use of NSAIDs?
Low GFR, loss of vasodilatory prostaglandins increasing afferent resistance (vasoconstriction), increased angiotension II (vasoconstriction)
What happens to GFR, vasodilatory prostaglandins and angiontension II with the use of ACE-I or ARB?
Low GFR, slightly increase vasodilatory prostaglandins (vasodilation) and decreased angiotension II (vasodilation)
What are three major causes of intrinsic acute kidney injury (AKI)?
Sepsis, Ischemia, and nephrotoxins
Which of the following is not a common key element of progressive nephropathies in CKD?
A. Increased filtration area
B. Increased glomerular capillary pressure
C. Proteinuria
D. Glomerulosclerosis
A. Increased filtration area
Which of the following are key abnormalities that give rise to CKD-MBD?
A. Hypercalcemia
B. Impaired phosphate excretion
C. Decrease production of active Vit D
D. Decreased PTH production
B. Impaired phosphate excretion
C. Decrease production of active Vit D
Which of the following is most important in CDK patients along with Vit D?
A. Sodium
B. Potassium
C. Calcium
D. Magnesium
C. Calcium
What illness is due largely to the accumulation of organic waste products that are normally cleared by the kidneys?
Uremia
Identify the following for nephrotic syndrome:
-Onset
-Edema
-BP/Venous pressure
-Proteinuria
-Hematuria
-RBC casts
-Serum albumin
Explain the etiology
-Onset: Insidious
-Edema: High (++++)
-BP/Venous pressure: normal
-Proteinuria: High (++++)
-Hematuria: variable
-RBC casts: absent
-Serum albumin: low
High proteinuria leads to lower serum albumin which increases edema
Identify the following for nephritic syndrome:
-Onset
-Edema
-BP/Venous pressure
-Proteinuria
-Hematuria
-RBC casts
-Serum albumin
Explain the etiology
-Onset: abrupt
-Edema: slight raise (++)
-BP/Venous pressure: Raised
-Proteinuria: slight raise (++)
-Hematuria: Raised (+++)
-RBC casts: Present
-Serum albumin: Normal/slight reduce
Increased RBC casts leading to hematuria
What condition is inflammation of the glomeruli from Alport Syndrome, infections, drugs, and autoimmune disorders such as Lupus?
A. Pyelonephritis
B. Glomerulonephritis
C. Nephrolithiasis
D. Interstitial Nephritis
B. Glomerulonephritis
What condition presents inflammation of kidney tissue with causes from bacteria from blood or urinary tract?
A. Pyelonephritis
B. Glomerulonephritis
C. Nephrolithiasis
D. Interstitial Nephritis
A. Pyelonephritis
Which of the following is injury to renal tubules and interstitium? It is commonly undetected until decreases in renal function and primarily caused from drugs (antibiotics)
A. Pyelonephritis
B. Glomerulonephritis
C. Nephrolithiasis
