Q

In CKD patients can experience:

  • loss of appetite
  • nausea
  • vomiting
  • encephalopathy
  • headaches
  • blurred vision
  • pericarditis

What is the primary call for all of these symptoms?

1 - dehydration
2 - uraemia
3 - anaemia
4 - hyponatraemia

A

2 - uraemia
- essentially build up of toxins in the blood of urea
- ammonia produced from amino acid metabolism can also be high and cause these symptoms
- ammonia is converted to urea in kidney

Q

What is the primary reason for anaemia in CKD?

1 - haematuria
2 - insufficient anti- coagulant proteins causing bleeding
3 - high levels of erythropoietin
4 - low levels of erythropoietin

A

4 - low levels of erythropoietin
- erythropoietin stimulates bone marrow to make more RBCs

Q

How can CKD cause weak and brittle bones?

1 - unable to activate vitamin D
2 - re-absorbs too much Ca2+
3 - uraemia inhibits PTH release
4 - all of the above

A

1 - unable to activate vitamin D
- Ca2+ is not re-absorbed as well, no increase in Ca2+ absorbed from GIT
- PTH is released to increase Ca2+ from bone
- over time this causes renal osteodystrophy

Q

Why can CKD result in hyperventilation?

A

4 - all of the above
- hyperkalaemia causes metabolic acidosis
- HCO3- is insufficient to compensate

Q

Diabetes is the leading cause of CKD, and is linked with non-enzymatic glycation (due to hyperglycaemia) that causes hyaline atherosclerosis, a thickening of the basement membranes. In relation to the kidney where does this affect 1st?

Q

Diabetes is the leading cause of CKD. Which of the following is NOT an affect that leads to CKD in patients with diabetes?

1 - non-enzymatic glycation (due to hyperglycaemia) that causes hyaline atherosclerosis
2 - narrowing of afferent arteriole

2 - narrowing of afferent arteriole
- can occur, but typically it is the efferent arteriole affected, which makes it harder for blood to leave glomerulus

Q

Hypertension can cause CKD. Which of the following is NOT an affect that leads to CKD in patients with hypertension?

A

1 - renal arteries dilate

2 - Co-development of HF and CKD
- diabetes, sepsis, etc..

62
Q

Treating patients with cardio-renal syndrome can be difficult. What should the primary aim of treating patients with CRS be?

1 - reduce eGFR
2 - reduce cardiac workload
3 - offload fluid
4 - increase cardiac output

A

3 - offload fluid
- larger than usual dose of diuretics may be required

63
Q

Treating patients with cardio-renal syndrome can be difficult. in patients with CHF, which of the following is often resistant to diuretics?

1 - hyponatraemia
2 - hypernatraemia
3 - hypercalcaemia
4 - hypocalcaemia

A

1 - hyponatraemia

  • if diuretic resistant dialysis or filtration may be used
64
Q

Treating patients with cardio-renal syndrome can be difficult. The kidneys are especially sensitive to nephrotoxic drugs. Which of the following is NOT nephrotoxic?

1 - NSAID
2 - ACE inhibitors
3 - diuretics
4 - aminoglycosides (Gentamicin)

A

3 - diuretics

  • ACE inhibitors are great for cardiac function, but can be bad for the kidneys
  • ACE inhibitors can also cause hyperkalaemia, which can be made worse with CKD that cannot filter out K+
65
Q

In a patient with liver cirrhosis there is a reduced effective blood volume. What can this lead to an increase in?

1 - increased aldosterone
2 - decreased RAAS activation
3 - decreased ADH
4 - increased TSH

A

1 - increased aldosterone
- reduced effective blood volume causes hypotension and activation of the RAAS
- RAAS system stimulates the release of aldosterone

66
Q

In a patient with liver cirrhosis there is a reduced effective blood volume, which leads to increased activation of RAAS and aldosterone levels. What electrolyte is often increased in liver cirrhosis?

1 - K+
2 - Na+
3 - Mg2+
4 - Ca2+

A

2 - Na+
- made worse if you have a salty meal
- patients often do not respond to diuretics

MUST REDUCE SALT INTAKE IF SALT INTAKE EXCEEDS NA+ EXCRETION AS INCREASES WATER RETENTION

67
Q

In patients hospitalised with liver cirrhosis, AKI is much more likely. Of those with an AKI, what is the most common cause of CKD?

1 - pre-renal
2 - intra-renal
3 - post-renal
4 - all equally affected

A

1 - pre-renal

68
Q

In patients hospitalised with liver cirrhosis, AKI is much more likely. Of those with an AKI, the most likely cause of CKD was pre-renal pathology. This can be divided into fluid responsive and fluid unresponsive. Of the the fluid responsive patients, which of the following is a likely cause of the CKD?

1 - infection
2 - vasodilators
3 - hypovolaemia
4 - all of the above

A

4 - all of the above

69
Q

In patients hospitalised with liver cirrhosis, AKI is much more likely. Of those with an AKI, the most likely cause of CKD was pre-renal pathology. This can be divided into fluid responsive and fluid unresponsive. Of the the fluid responders patients, which of the following is a likely cause of the AKI?

1 - CHF
2 - hepato-renal syndrome
3 - encephalopathy
4 - pulmonary oedema

A

2 - hepato-renal syndrome

70
Q

Patients with hepato-renal syndrome typically have which of the following?

1 - portal hypertension
2 - severe alcoholic hepatitis
3 - alcoholic liver cirrhosis
4 - metastatic tumour
5 - all of the above

A

5 - all of the above

  • as liver function declines so to does perfusion of the kidneys, leading to AKI and eventually CKD
71
Q

Does hepato-renal syndrome have a good or bad prognosis?

A
  • bad prognosis
72
Q

There are 2 types of hepato-renal syndrome (HRS). Which of the following is type 1 and type 2 HRS?

1 - Diuretic resistant ascites: Less rapid deterioration in renal function; associated with refractory ascites and poor survival (months)

2 - HRS-AKI: Oliguric, doubling of serum creatinine within 2 weeks; outcome is poor (days to weeks) with a precipitating insult

A

1 - Diuretic resistant ascites: Less rapid deterioration in renal function; associated with refractory ascites and poor survival (months)
= TYPE 2

2 - HRS-AKI: severe and rapid decline, oliguric, doubling of serum creatinine within 2 weeks; outcome is poor (days to weeks) with a precipitating insult (i.e. infection) and often need recurrent paracentesis
= TYPE 1

73
Q

n hepato-renal syndrome, does type 1 or type 2 have a better mortality rate?

A
  • type 2
  • type 1 = 2 weeks
  • type 2 = 4-6 months
74
Q

In hepato-renal syndrome, why is creatinine often a bad marker?

1 - patients levels become too high to measure
2 - slow to respond to changes
3 - patients are cachexic, malnourished and liver disease)
4 - creatinine does not reach the kidneys

A

3 - patients are cachexic, malnourished and liver disease)

  • they don’t have the levels of creatinine to rise, but kidney damage is present
75
Q

The prognosis in hepato-renal syndrome (HRS) is poor and treatment is often supportive in nature. Which of the following is NOT an aspect of treatment in HRS?

1 - Na+ and H20 restriction
2 - albumin supplements
3 - treat tigger of HRS
4 - terlipressin
5 -

A
76
Q

Terlipressin, which is a vasopressin analogue can be used in patients with hepato-renal syndrome (HRS). Where does Terlipressin have its main effects?

1 - blood flow to kidneys
2 - increased preload to heart and increase blood flow to the kidneys
3 - reduces afterload in patients
4 - vasoconstricts the splanchnic circulation

A

4 - vasoconstricts the splanchnic circulation

  • Terlipressin = vasoconstrictor
  • increased vasoconstriction of the splanchnic circulation will aim to increase perfusion of the kidneys
77
Q

Terlipressin, which is a vasopressin analogue can be used in patients with hepato-renal syndrome (HRS). Which 2 of the following can be performed in one of the specialist liver units if available?

1 - Transjugular intrahepatic portosystemic shunt (TIPS)
2 - Transplantation
3 - Dialysis
4 - all of the above

A

4 - all of the above

  • TIPS = removes fluid from portovenous system and redivert blood flow to the kidneys
  • dialysis = not great, prolongs suffering and not great treatment
  • lung transplantation is often not suitable either
