A

RAAS

4
Q

Function of prostaglandins

A

Control glomerular functions

5
Q

Excess urine

6
Q

Definition of dysuria

A

Pain when passing urine

7
Q

Definition of haematuria

A

Blood in urine

8
Q

Definition of proteinuria

A

Protein in urine

9
Q

Definition of uraemia

A

Excess urea in blood

10
Q

Renal function is measured by (3)

A

Serum urea
Serum creatinine
24hr urine collection (creatinine clearance)

11
Q

Renal failure involves (4)

A

Loss of renal excretory function
Loss of water and electrolyte balance
Loss of acid base balance
Loss of renal endocrine function (EPO, calcium metabolism, renin secretion)

12
Q

Renal failure can be (2)

A

Acute (usually reversible)

Chronic

13
Q

Features of acute renal failure

A

Rapid loss of renal function, usually over hours/days

14
Q

Features of chronic renal failure

A

Gradual loss of renal function, usually over many years

15
Q

Causes of renal failure (3)

A

Pre-renal
Renal
Post-renal

16
Q

Definition of pre-renal failure and examples (3)

A

Hypo-perfusion of kidney
Shock
Renal artery disease
Aorta disease

17
Q

Examples of renal failure (4)

A

Chronic disease
Drug damage
Trauma
Rhabdolysis

18
Q

Definition of rhabdolysis

A

Breakdown of skeletal muscle

19
Q

Examples of post-renal failure

A

Renal outflow obstruction

20
Q

Acute renal failure involves (5)

A
Rapid loss of renal function
Anuric initially with volume overload
Gradual progression to polyuria
Development of hyperkalaemia
Development of uraemia and acidosis
21
Q

Weight gain
23
Q

Effects of acidosis (3)

24
Q

Main cause of acute renal failure

A

Pre-renal cause

25
Q

Specific cause and example of acute renal failure (2)

A

Trauma/drug-induced

Crush injury –> muscle breakdown –> uraemia –> kidneys blocked –> acute failure

30
Q

Complications of glomerulonephritis

A

Nephrotic syndrome

31
Q

Nephrotic syndrome involves (4)

A

Excessive loss of protein in urine (leads to hypoalbuminaemia)
Loss of plasma oncotic pressure
Tissue swelling (oedema)
Hypercoagulable state (loss of clotting factors)

32
