Acute blood loss

Question 4

How will you assess for renal AKI/other causes of AKI

Answer 4

ATN from contrast / drugs - stop these drugs
Glomerulonephritis/acute interstitial nephritis
Rhabdomyolysis

Question 5

Post-renal causes of AKI

Answer 5

Stones
Cancer - bladder, prostate, retroperitoneal
BPH
Neurogenic bladder

Question 6

Invx for AKI

Answer 6

Urinalysis
Infection - leucocytes and nitrites
Acute nephritis - protein and blood

Na level excreted in kidney - less excretion in post renal

Medications
Glomerulonephritis
PKD

Question 23

Investigation for CKD

Answer 23

eGFR/creatinine

ACR/PCR to quantify proteinuria

haematuria with urine dip/micrsoppcy

USS

BP, HBA1c, Lipid profile, nephritis screen

Question 24

Answer 24

Control underlying disease e.g. diabetes
BP control
Minimise proteinuria

ACEi/ARB
SGLT2
Exercise

Question 25

Problems due to CKD

Answer 25

Anaemia - loss of EPO - give erythropoetin/iron Acidosis Bones - give Vit D Clearance Drugs Electrolytes Fluid balance

Question 26

AV Fistula auscultation signs

Answer 26

machinery murmur thrill

Question 27

AV fistula complications

Answer 27

Hand ischemia - STEAL syndrome High output failure

Question 28

Tunnelled dialysis lines

Answer 28

Over clavicle Tunnelled dialysis lines / tesio lines for haemodialysis

Question 29

Tenckhoff catheter use vs tesio line

Answer 29

For peritoneal dialysis - tenkckhoff catheter tesio line = haemodialysis

Question 30

Why are ACE inhibitors differentially preferred in AKI vs CKD

Answer 30

Efferent arteriole vasodilation, less glomerular flow - bad in AKI But this is protective in CKD

Question 31

When do you give ACEi in chronic kidney disease?

Answer 31

Anyone with proteinuria should be on an ACEi
