Question 1
Correct
-
An 83-year-old gentleman presents to his GP with increasing oedema and ascites. He is hypertensive, for which he takes amlodipine. There is shortness of breath on exercise. His alcohol history is two cans of stout per day.
ECG is normal, and CXR reveals normal heart size and no signs of cardiac failure. Serum albumin is 23 g/dl; urinary albumin excretion is 7 g/24 h, with no haematuria. He has mild anaemia with a normal MCV. Total cholesterol is elevated.
What diagnosis fits best with this clinical picture?Your Answer: Nephrotic syndrome
Explanation:Nephrotic syndrome usually presents with the symptoms in this patient: low albumin, abnormal cholesterol, increased urinary albumin excretion, oedema, and as a consequence, hypertension as well.

Question 2
Correct
-
A patient with chronic renal failure, treated with regular haemodialysis, attends the renal clinic. He has been treated for six months with oral ferrous sulphate, 200 mg three times a day. His haemoglobin at this clinic attendance is 7.6. His previous result was 10.6 six months ago.
Which of the following is the most appropriate treatment?Your Answer: IV iron and subcutaneous erythropoietin
Explanation:The patient should be prescribed IV iron and subcutaneous erythropoietin to enhance erythropoiesis to address the dropped haemoglobin.

Question 3
Incorrect
-
A 35-year-old gentleman presents to the Emergency Department with abdominal pain. This started earlier on in the day and is getting progressively worse. The pain is located on his left flank and radiates down into his groin. He has no history of this pain or any other condition. Examination reveals a gentleman who is flushed and sweaty but is otherwise unremarkable. What is the most suitable initial management?
Your Answer: IM diclofenac 75 mg + start bendroflumethiazide to prevent further episodes
Correct Answer: IM diclofenac 75 mg
Explanation:Because of the patient’s presentation with flank pain that radiates to the groin, we are suspecting renal colic. We should follow guidelines for acute renal management and prescribe IM diclofenac for immediate relief of pain.

Question 4
Correct
-
A 50-year-old gentleman with renal cell carcinoma has a haemoglobin of 19 g/dl. Which investigation will conclusively prove that this patient has secondary polycythaemia?
Your Answer: Erythropoietin level
Explanation:Erythropoietin (EPO) is used to distinguish between primary and secondary polycythaemia. Secondary polycythaemia can be caused by tumours in the kidney that may secrete EPO or EPO-like proteins.

Question 5
Correct
-
A 26 year-old gentleman presented with complaints of multiple bruises over his body and reddish urine after a road traffic accident. Labs showed deranged renal function. The best management step would be?
Your Answer: IV normal saline
Explanation:Rhabdomyolysis occurs after severe muscles injury and the patient presents with myoglobinuria and deranged RFTS. The best initial step in management is fluid resuscitation with normal saline. If initial management fails to treat the patient, we can go to haemodialysis.

Question 6
Correct
-
A 48-year-old patient with type 1 diabetes and chronic kidney disease attends for review. His blood tests show:
Haemoglobin 11.2 g/dl (13.0 - 18.0 g/dL)
MCV 87 fl (80 - 96 fL)
Sodium 133 mmol/l (137 - 144 mmol/L)
Potassium 4.3 mmol/l (3.5 - 4.9 mmol/L)
Urea 19.1 mmol/l (2.5 - 7.5 mmol/L)
Creatinine 267 μmol/l (60 - 110 μmol/L)
Ferritin 150 μg/l (15 - 300 μg/L)
C reactive protein <5 mg/l (< 10 mg/L)
What is the most appropriate management of his anaemia?Your Answer: Monitor haemoglobin, no treatment required at present
Explanation:Because the patient has chronic kidney disease, we need to consider the associated adverse effects of trying to maintain normal haemoglobin levels (14-18g/dl in this patient) and instead only instigate therapy when the level falls below 11 g/dl. Thus, in this case we should just monitor the haemoglobin levels and not initiate therapy just yet.

Question 7
Correct
-
In renal patients, bone reabsorption and fractures are significant due to high level of parathyroid hormone. Which one of the following is a major culprit for this high level of parathyroid hormones?
Your Answer: Hyperphosphataemia
Explanation:Hyperphosphatemia is the cause known to enhance the production of PTH through parathyroid glands in renal patients. Hypercalcaemia and Hypophosphatemia decrease PTH production. Phosphate binders also reduce PTH level. Serum ALP is an indicator of rapid bone turnover.

Question 8
Incorrect
-
A 3-year-old boy presents with facial puffiness, frothy urine, lethargy and oliguria for two weeks. Urine analysis reveals proteinuria. Which of the following is the most appropriate treatment for this child?
Your Answer: Diuretics
Correct Answer: Prednisolone
Explanation:The presentation is suggestive of nephrotic syndrome. A trial of corticosteroids is the first step in treatment of idiopathic nephrotic syndrome. Diuretics are useful in managing symptomatic oedema. Cyclosporin and cyclophosphamide are indicated in frequently relapsing and steroid dependant disease.

Question 9
Correct
-
A 26-year-old patient, previously fit and well, is admitted with fluctuating confusion and frank haematuria. He has recently been complaining of generalised malaise and joint pains. Examination reveals jaundice, splenomegaly, and petechiae. His blood pressure is 155/84 mmHg, temperature 37.9oC.
Initial investigations reveal:
Haemoglobin 9.5 g/dl
White cell count 12 × 109/l
Platelets 40 × 109/l
Creatinine 142 μmol/l
Sodium 139 mmol/l
Potassium 4.5 mmol/l
Urea 9.2 mmol/l
Lactate dehydrogenase 495 U/l (10-250)
Urinalysis Protein ++, blood +++
Blood film shows schistocytes
What treatment should NOT be given to this patient?Your Answer: Platelet transfusion
Explanation:There is a strong suspicion of Thrombotic Thrombocytopenic Purpura (TTP) in this patient as he presents with neurological changes (from confusion to convulsions and coma), fever, haemolysis, thrombocytopenia, and renal failure. Additionally, TTP cases may present with jaundice, splenomegaly, and hypertension as seen in this patient. With a diagnosis of TTP, recent studies have shown that platelet transfusion is not recommended in this case because it has been shown to increase the risk for arterial thrombosis and mortality possibly due to increased aggregations.

Question 10
Correct
-
A 28-year-old male has presented to his doctor with hypertension. Upon examination, he is found to have palpable kidneys. An abdominal ultrasound shows enlarged cystic kidneys on both sides. From the list of options, choose the most likely condition present in this patient.
Your Answer: Polycythaemia
Explanation:The most likely diagnosis for this patient is adult polycystic kidneys. This disease is associated with the following: valvular heart abnormalities, incompetence, and aneurysms of the cerebral circulation. It can also be associated with excessive erythropoietin production and polycythaemia. There is an increased incidence of aortic incompetence, and mitral valve prolapse occurs in 25 per cent of patients. Hepatic cysts can also occur, and present in 70 per cent of patients – these can also involve the pancreas in 10 per cent of patients and the spleen. Cerebral berry aneurysms are present in around 5-8 per cent of patients, but familial clustering is also observed. That is if there is a family history, over 20 per cent of patients will also have an aneurysm. Diverticular disease is also thought to be increased in patients with polycystic kidney disease.
