A 23-year-old female presents to the hospital with complaints of abdominal pain, loose stools, wrist and ankle pain, and a sore throat three days prior. Upon examination, a non-blanching maculopapular rash is observed on her back, buttocks, and lower legs, and her blood pressure is elevated at 175/90 mmHg.

MRCP2-4073
A 39-year-old known ulcerative colitis (UC) patient presents to the emergency department with sudden onset severe pain in the left loin to groin area. The patient has no other medical issues and had a panproctocolectomy and ileostomy 4 years ago after a colitis flare that did not respond to medical treatment. During the examination, the patient is visibly in pain, and the urine dip shows 3+ RBCs. The patient is given diclofenac and 5 mg IV morphine, which helps alleviate the pain. After the patient is pain-free, their vital signs are normal.
The blood tests reveal:
– Hb 145 g/l – Platelets 455 * 109/l – WBC 11.9 * 109/l – Na+ 136 mmol/l – K+ 4.5 mmol/l – Urea 8.8 mmol/l – Creatinine 99 µmol/l – Calcium (adj) 2.48 mmol/L – CRP <10 mg/L
A KUB X-ray is performed, which shows a stone in the ureter on the left side. What type of renal stone is likely causing the patient’s symptoms?
MRCP2-4074
A 43-year-old woman with known systemic lupus erythematosus presents with a 3-month history of fatigue, bilateral leg swelling and increasing abdominal distension. On examination, she had periorbital oedema, ascites and pitting oedema to the groin. Her chest was clear, the heart sounds were normal and her jugular venous pressure was not raised. Investigations reveal abnormal results for haemoglobin, white cell count, platelets, mean corpuscular volume, albumin, sodium, potassium, bilirubin, urea, alkaline phosphatase, creatinine, aspartate transaminase, cholesterol, urinalysis and 24-hour urinary protein excretion. She was commenced on treatment with high-dose diuretics and immunosuppressant therapy. Several weeks later, she was readmitted with abdominal pain. On examination, she had mild pyrexia and was tender in both loins. Repeat investigation reveals abnormal results for haemoglobin, white cell count, creatinine, sodium, potassium, urea, urinalysis and blood. What is the most likely cause for the acute deterioration in renal function?
MRCP2-4075

Observations are as follows: temperature 36.3ºC, blood pressure 179/111 mmHg, heart rate 89/min, respiratory rate 16/min, saturations 97% on air
Urine: blood ++, nitrites -ve, leucocytes -ve, protein +++
What is the most likely underlying diagnosis for this 38-year-old patient?
MRCP2-4076
A 55 year-old man presents with right flank pain. The pain is 9/10 on the pain scale, and does not radiate anywhere. He has also suffered from thirst, polyuria and fatigue, which he has put down to stress from being off work due to a history of chronic lumbar back pain. He has a smoking history of 10 pack years and drinks on average a couple of pints of beer at the weekends. He has no relevant family history.
On examination, he has tenderness in the right flank and lower back and his blood pressure is 149/92 mmHg. Blood tests reveal Hb 9.9 g/dL, platelets 284 * 109/l, WBC 10.5 * 109/l, mean corpuscular volume 86 fl, Na+ 129 mmol/l, K+ 3.9 mmol/l, urea 16.3 mmol/l, creatinine 410 µmol/l, calcium 2.19 mmol/l, phosphate 1.79 mmol/l, and uric acid 0.40 mmol/l.
Urinalysis reveals protein ++, leucocytes +. Microscopy reveals renal papillary cells and casts. No organisms are identified. A plain abdominal x-ray is negative for calculi and calcification. Intravenous urogram reveals clubbed calyces and ring signs.
What is the most likely diagnosis?
MRCP2-4077
A 32-year-old man presents to the hospital with a 4-day history of feeling generally unwell, experiencing fatigue, joint pain, and itching. He had recently completed a 7-day course of antibiotics for a respiratory infection but has no significant medical history. On clinical examination, he has a widespread red rash. The following investigations were conducted: Haemoglobin (Hb): 130 g/l (normal range: 130-170 g/l) White cell count (WCC): 12.5 × 109/l (with eosinophilia) (normal range: 4.0-11.0 × 109/l) Platelets (PLT): 380 × 109/l (normal range: 150-400 × 109/l) Creatinine (Cr): 710 μmol/l (normal range: 60-110 μmol/l) Sodium (Na+): 138 mmol/l (normal range: 135-145 mmol/l) Potassium (K+): 5.0 mmol/l (normal range: 3.5-5.0 mmol/l) Urea: 20.0 mmol/l (normal range: 2.5-6.5 mmol/l) Urinalysis: Protein ++, blood + What is the most crucial investigation to establish the diagnosis?
MRCP2-4078
A 42-year-old Indian man is seen in the renal outpatient clinic. He has been experiencing a gradual decline in his renal function for the past 4 years due to poorly controlled type 2 diabetes mellitus. His eGFR is currently at 8 ml/min, but he is still able to pass urine. Recent ultrasound scans have indicated that he is a suitable candidate for a renal transplant. However, given his ethnicity, there is an uncertain wait for organ suitability should he choose to pursue this option. During the consultation, his 17-year-old daughter offers to donate a kidney due to the high likelihood of compatibility, which the patient is interested in exploring.
What would be the most appropriate course of action at this point?
MRCP2-4079
A 25-year-old man presents to his GP with a history of recurrent haematuria during upper respiratory tract infections or flu-like illnesses over the past year. On examination, there were no abnormalities detected. A dipstick test revealed micro-haematuria with mild proteinuria, and his urea and electrolytes were normal. The patient’s serum IgA levels were elevated. What is the most probable diagnosis?
MRCP2-4080

Based on these findings, what is the most likely diagnosis?
MRCP2-4081
A 35-year-old construction worker presents for review. He visited the doctor complaining of fatigue and weakness, abdominal discomfort and migraines. He works regularly on building sites.
