Question Easy:
A 45-year-old woman presents with swelling in her legs and puffy eyes. You suspect nephrotic syndrome. Which of the following lab findings is most characteristic for this condition?
A) Hypercalcaemia
B) Hypermagnesaemia
C) Proteinuria
D) Leukocytosis
E) Hyperkalaemia
Explanations & Answers:
Question Easy Answer:
C) Proteinuria
Question Easy Explanation:
Proteinuria is a hallmark of nephrotic syndrome, often exceeding 3.5 grams per day. Nephrotic syndrome is characterised by massive protein loss in urine, low blood protein levels, high cholesterol levels, and swelling. The presence of proteinuria in this scenario helps confirm the diagnosis.
Question Medium:
A 70-year-old man presents with vomiting, confusion, and a gradual reduction in urine output over the past week. His plasma creatinine level is significantly elevated. Which of the following is the most likely diagnosis?
A) Chronic kidney disease
B) Acute kidney injury
C) Nephrolithiasis
D) Urinary tract infection
E) Polycystic kidney disease
Explanations & Answers:
Question Medium Answer:
B) Acute kidney injury
Question Medium Explanation:
Acute kidney injury (AKI) is often characterised by a rapid decline in renal function, leading to increased creatinine levels, reduced urine output, and possible fluid retention resulting in symptoms like vomiting and confusion. In accordance with NICE guidelines, AKI requires prompt identification and management to prevent complications.
Question Hard:
A 58-year-old man presents with an asymptomatic right renal mass found incidentally on CT scan. His blood tests are normal with no visible haematuria or weight loss. What is the most appropriate next step in management?
A) Immediate nephrectomy
B) Regular surveillance with imaging
C) Renal biopsy
D) Start chemotherapy
E) Initiate dialysis
Explanations & Answers:
Question Hard Answer:
B) Regular surveillance with imaging
Question Hard Explanation:
For small renal masses or renal cell carcinoma that do not show aggressive features and the patient is asymptomatic and stable, regular surveillance with imaging can be appropriate, especially in the elderly or those with significant comorbidities. This approach aligns with UK guidelines focusing on balancing the risks of intervention against the tumour behaviour.
