Question Easy: 🚽 A 30-year-old woman presents to her GP with dysuria and increased urinary frequency. A urine dipstick test shows positive nitrites and leukocytes. Which of the following is the most appropriate initial treatment?
A) Trimethoprim
B) Nitrofurantoin
C) Amoxicillin
D) Ciprofloxacin
E) Co-amoxiclav
Explanations & Answers:
Question Easy Answer: B) Nitrofurantoin

Nitrofurantoin is effective against common UTI pathogens and has good urinary excretion.
Question Medium: 💧 A 52-year-old man presents with polyuria, polydipsia, and a serum sodium level of 150 mmol/L. His urine osmolality is 100 mOsm/kg after a water deprivation test, which then increases to 500 mOsm/kg after administration of desmopressin. What is the most likely diagnosis?
A) Primary polydipsia
B) Central diabetes insipidus
C) Nephrogenic diabetes insipidus
D) Hyperglycaemia
E) Acute tubular necrosis
Question Medium Answer: B) Central diabetes insipidus
Question Medium Explanation: Central diabetes insipidus results from a deficiency of antidiuretic hormone (ADH). The key diagnostic feature is a significant increase in urine osmolality after desmopressin administration during a water deprivation test. In this scenario, the patient’s urine osmolality increased only after desmopressin, indicating a central cause.
Question Hard: 🔬 A 70-year-old man with a history of hypertension and diabetes presents with a dull, aching pain in the flank and a palpable abdominal mass. An abdominal ultrasound shows a large, solid renal mass with mixed echogenicity. Which of the following is the most likely diagnosis?
A) Renal cell carcinoma
B) Angiomyolipoma
C) Simple renal cyst
D) Urothelial carcinoma
E) Oncocytoma
Question Hard Answer: A) Renal cell carcinoma
Question Hard Explanation: Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults. It is often characterized by a triad of symptoms: flank pain, palpable mass, and hematuria. The ultrasound findings, combined with the patient’s age and symptoms, are suggestive of RCC.
