A 3-year old boy presents with an abdominal mass. Which of the following is associated with Wilms tumour (nephroblastoma)?
Your Answer: Beckwith-Wiedemann syndrome
Explanation:Beckwith-Wiedemann syndrome is a inherited condition associated with organomegaly, macroglossia, abdominal wall defects, Wilm’s tumour and neonatal hypoglycaemia. Wilm’s tumour is a kidney cancer that usually occurs in children. The causes are unknown, however, risk factors include race and family history. Of note, Wilm’s tumour can occur as part of the following syndromes: WAGR syndrome, Denys-Drash syndrome, and Beckwith-Wiedmann syndrome and not the other listed options in this question.

A 48-year-old male with a history of bipolar disorder presents with acute confusion. In-transit to hospital he had a generalized seizure which terminated spontaneously after around 30 seconds. On arrival to the emergency department, his GCS is 14/15 and he is noted to have a coarse tremor. Suspecting a diagnosis of lithium toxicity, intravenous access is obtained, a blood sample was drawn for investigations and a saline infusion is started. The blood investigations revealed:
Lithium level: 4.2 mmol/l
Na+: 136 mmol/l
K+: 4.6 mmol/l
Urea: 8.1 mmol/l
Creatinine: 99 µmol/l
Bicarbonate: 18 mmol/l
What is the most appropriate management for the patient?Your Answer: Arrange haemodialysis

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: 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.

A 3-year-old girl is brought to the clinic by her mother due to burning micturition, frequency and urgency. She is also experiencing some suprapubic tenderness. Which of the following investigations should be done initially?
Your Answer: Clean catch of urine for Culture &Sensitivity
Explanation:Urine culture and sensitivity is used to diagnose a urinary tract infection (UTI). A mid-stream clean catch urine sample is the most common type of sample collected. It is important to follow the clean catch process to have accurate results from an uncontaminated sample. Urine cultures can also check for infections of the bladder or kidney.

Question 6
Correct
-
A 71-year-old female presents for investigation of fatigue and weight loss.
Investigations reveal:
Haemoglobin 9.0 g/dL (11.5-16.5)
White cell count 2.0 x109/L (4-11 x109)
Platelet count 250 x109/L (150-400 x109)
Total protein 74 g/L (61-76)
Albumin 28 g/L (37-49)
Urea 16 mmol/L (2.5-7.5)
Creatinine 250 mol/L (60-110)
Plasma glucose 6.5 mmol/L (3.0-6.0)
Urine dipstick analysis: Protein+ & blood+
Renal ultrasound: Normal
Which one of the following investigations would be most appropriate for this patient?Your Answer: Plasma protein electrophoresis
Explanation:This patient’s symptoms of anaemia, leukopenia, and elevated non-albumin protein concentration with fatigue and weight loss, point to myeloma. Thus plasma protein electrophoresis or Serum Protein Electrophoresis (SPE) is indicated when there is suspicion of myeloma.

Question 7
Correct

A 69-year-old woman is admitted with confusion. She's known to have a history of multiple myeloma. Blood exam reveals the following: Na+ = 147 mmol/l, K+ = 4.7 mmol/l, Urea = 14.2 mmol/l, Creatinine = 102 μmol/l, Adjusted calcium = 3.9 mmol/l. What is the single most appropriate management?
Your Answer: IV 0.9% saline
Explanation:NICE guidelines on hypercalcemia recommend that maintaining good hydration equals drinking 3-4 L of fluid/day, provided there are no contraindications. A low calcium diet is not necessary because intestinal absorption of calcium is reduced. The patient should avoid any other drugs or vitamins that could worsen the hypercalcemia. Mobilization is encouraged and any symptoms of hypercalcemia should be reported.

Question 8
Incorrect
-
A 61-year-old woman with a history of hypothyroidism and inflammatory arthritis is admitted after slipping on ice and falling over. Some routine blood tests are performed:
Na+ 141 mmol/l
K+ 2.9 mmol/l
Chloride 114 mmol/l
Bicarbonate 16 mmol/l
Urea 5.2 mmol/l
Creatinine 75 µmol/l
Which one of the following is most likely to explain these results?Your Answer: Renal tubular acidosis (type 4)
Correct Answer: Renal tubular acidosis (type 1)
Explanation:The patient’s underlying arthritis has most likely led to Renal tubular acidosis RTA type 1, which presents with the following symptoms consistent with the presentation of the patient: Normal anion gap metabolic acidosis/acidaemia, hypokalaemia and hyperchloremia. Comparatively, the other conditions are ruled out because Aspirin and diabetic ketoacidosis is associated with a raised anion gap, Conn’s syndrome explains hypokalaemia but not the metabolic acidosis, and RTA type 4 is associated with hyperkalaemia.

A 40-year-old man presents with periorbital and pedal oedema. 24h urine shows 9g of protein/d and serum cholesterol of 7 mmol/L. What would be the most likely diagnosis?
Your Answer: FSGS
Correct Answer: Membranous glomerulonephropathy
Explanation:Membranous glomerulonephritis . However some authors believe FSGS a more commoner cause of nephrotic syndrome.

Question 10
Correct
-
A 58-year-old lady was admitted to hospital with increasing thirst and generalised abdominal pain. She was diagnosed with breast carcinoma three years previously and treated with a radical mastectomy.
Investigations showed:
Serum corrected calcium 3.5 mmol/L (NR 2.2-2.6)
Serum alkaline phosphatase 1100 IU/L
Her serum calcium was still elevated following 4 litres of 0.9% saline intravenous infusion.
Which of the following is the most appropriate next step?Your Answer: Pamidronate 60 mg intravenously
Explanation:This case has hypercalcaemia most likely associated with the bony metastases from her pre-existing breast carcinoma. The most appropriate next step is to give Pamidronate 60mg intravenously, a bisphosphonate, to immediately inhibit bone resorption and formation.
