What is the Renal Medicine ST4 interview, and how do you practise for it?
The Renal Medicine ST4 interview assesses how you reason and communicate under pressure in front of a panel. The most effective preparation is rehearsing your answers out loud to realistic questions — with MedMock you practise against an AI panel that asks the demanding follow-ups and get instant feedback.

Knowing the material is not the same as performing on the day
The Renal Medicine ST4 interview is won in the room, not on paper. Strong candidates lose offers because they ramble, lose their thread on a follow-up, or fail to convey their reasoning clearly under pressure.
The solution is rehearsal — out loud, against someone who probes like a real panel. Yet mock interviews are hard to arrange, expensive when available, and candidates rarely get more than one or two before the real interview.
Renal Medicine ST4 interview practice, on demand
JRCPTB / NHS England Medical Hub Physician Higher Specialty Training national selection for ST4 entry into Renal Medicine (Nephrology). Two examiner-led stations / four questions, anchored to the Renal SAC curriculum and to KDIGO, UK Kidney Association (UKKA) standards, NICE NG148 (AKI) / NG203 (CKD) / NG228, BTS / NHSBT transplant guidance and the Internal Medicine Stage 1 Capabilities in Practice. Station 1 (15 min) — Q1 Clinical Scenario + Q2 Ethical Scenario with a parallel communication mark. Station 2 — Q1 Medical Registrar Suitability (opens with a 1-minute candidate presentation on managing the acute unselected take; probes CiP1 + CiP2) + Q2 Suitability & Commitment to renal medicine.
MedMock gives you an interview panel that challenges your answers, available 24/7.

How it works
Choose a question
Choose the kind of question or scenario you want to rehearse — ethics, motivation, a clinical dilemma, and more.
Have the conversation
Speak naturally, out loud. The AI panel listens and asks the demanding follow-ups, exactly like the real interview.
Get instant feedback
The moment you finish, you get specific, examiner-style feedback and a score — what you did well, what cost you marks, and precisely what to fix before the next attempt.
Why candidates practise with MedMock
Practise out loud, any time
No study partner, no booking, no rota clash. Open MedMock at 6am or midnight and run a full question in minutes.
All 4 questions, endless variations
You will never simply memorise answers. Each run is different, so you build the real skill — adapting in the moment.
Examiner-level feedback in seconds
Know exactly where you lost marks and how to address it, instead of guessing why a mock session went poorly.
Turn nerves into muscle memory
By the time you sit the Renal Medicine ST4, the format feels familiar — because you have already done it dozens of times.
A fraction of the cost of courses
Avoid the hundreds of pounds you would spend on a one-off interview course, and practise unlimited scenarios instead.
Practise anywhere, from your phone
On a break, during the commute, between jobs on the ward — your preparation goes wherever you do.
Practise every scenario
MedMock covers the questions you will face in the Renal Medicine ST4 interview. Rehearse each one until it feels routine.
Clinical Scenario
Station 1 Q1. 2-3 min pre-read of a brief clinical scenario, then panel-led probing on next steps, investigations, potential treatments, communication with patients/family/colleagues, and any other factors using your clinical experience. Registrar-grade acute nephrology — severe hyperkalaemia, rapidly progressive glomerulonephritis / ANCA vasculitis, AKI on CKD with crash-landing onto RRT, dialysis emergencies (intradialytic hypotension, line sepsis, peritonitis on PD), tumour-lysis syndrome, thrombotic microangiopathy (HUS/TTP), hepatorenal syndrome, contrast-associated AKI, transplant rejection and CNI toxicity. Probes KDIGO-anchored reasoning, modality choice (HD vs CVVH vs PD vs plasma exchange), prescription detail, escalation thresholds and MDT working with ICU, urology and transplant surgery. Communication is marked in parallel across the whole station.
Ethical Scenario
Station 1 Q2. Verbal ethical scenario delivered after the clinical scenario (no advance preparation). Tests moral, ethical, legal considerations rather than clinical knowledge — capacity and shared decision-making around dialysis initiation, conservative kidney management vs RRT, withdrawal of dialysis, transplant listing ethics (age, frailty, BMI, adherence concerns, paired / altruistic donation), living-donor consent and HTA workup, advance care planning, Duty of Candour HSCA 2008 Reg 20 after a dialysis adverse event, raising concerns about colleague performance or unit safety, GIRFT / UKKA-anchored renal-services governance, KQuIP improvement framework. Anchored to MCA 2005 and GMC Good Medical Practice 2024.
Medical Registrar Suitability
Station 2 Q1. Non-clinical medical-registrar competencies anchored to two Internal Medicine Stage 1 Capabilities in Practice — CiP1 (managing the acute unselected medical take) and CiP2 (multi-disciplinary team management including effective discharge planning). Opens with a strict one-minute candidate presentation summarising acute-take leadership experience: roles & duration, level of responsibility / degree of supervision, MDT size & profile, number of patients directly and indirectly responsible for, non-clinical duties undertaken. No slides; notes for own use only; stopped at the bell. Panel then probes named examples from your practice — competing priorities, MDT conflict, complex discharge, difficult family conversation, raising concerns proportionately.
Suitability & Commitment to Renal Medicine
Station 2 Q2. Suitability for and commitment to higher specialty training in renal medicine. Expanding on your application form — motivation anchored to dated touchpoints (named taster with named consultant and dates, dedicated renal block, UKKA / Renal Association Trainees Network (RaTN) engagement, regional renal meetings); completed audit or QIP with named standard, denominator, intervention, re-audit and measurable change (vascular access, AKI bundle, transplant follow-up); research output (basic science, clinical trial recruitment, UKKA registry work, MD / PhD plan); teaching with feedback evidence; SCE Nephrology booking; calibrated career plan and OOPR intent. Slogan motivation will not score.
Example scenarios
A sample of the scenarios you will practise — each plays out as a live, spoken conversation, not a script to read.
“A 72-year-old man two weeks post-deceased-donor renal transplant presents with fever, oliguria, a tender allograft and a creatinine that has risen from 130 to 280 µmol/L. Tacrolimus trough is 14 ng/mL. Talk me through your differential, immediate investigations, and how you would prioritise rejection workup versus infection in the first six hours.”
“You are the renal registrar called to a 58-year-old anuric patient on the AMU with a potassium of 7.4 mmol/L, peaked T-waves on ECG, pH 7.18 and a creatinine of 920 µmol/L. He has had no urine output for 18 hours and no functioning AV access. Walk me through your medical management and your plan for urgent RRT initiation, including line site and dialysis prescription.”
“A frail 84-year-old woman with CKD stage 5 (eGFR 8), heart failure and progressive cognitive decline is being pushed by her son towards starting haemodialysis. She tells you 'I just want to be left in peace at home'. The renal consultant is on annual leave. Discuss how you would approach this conversation, your capacity assessment, and the conservative kidney management pathway.”
“A junior trainee tells you in confidence that a tunnelled-line insertion list has had three pneumothoraces in the last month and the consultant has not declared them. Walk me through your Duty of Candour, governance and proportionate escalation steps.”
“Give us your one-minute summary of leading the acute unselected medical take. We will then ask you about a take in which two patients deteriorated simultaneously while the AMU sister was asking you to clear cubicles for ED breach pressure.”
“Tell us about a closed-loop audit you have led in nephrology — named standard, denominator, intervention, re-audit and measurable change — then explain why renal medicine specifically and what in the last 12 months beyond your application form confirms that commitment.”
Renal Medicine (ST4) practice — your questions answered
How realistic is MedMock's Renal Medicine ST4 practice?
Every scenario is built around the real Renal Medicine ST4 interview format and the domains examiners assess. You speak out loud and the AI panel asks genuine follow-ups, so it feels far closer to the day than reading notes or rehearsing silently.
How does the feedback work?
As soon as you finish a question, MedMock gives you instant, examiner-style feedback and a score — highlighting what you did well, what cost you marks, and exactly what to work on next.
Can I practise specific Renal Medicine ST4 questions?
Yes. You can pick any of the 4 questions to drill a weak area, or run a mixed set to simulate the real interview.
Do I need a study partner or a fixed time slot?
No. That is the point — MedMock is available 24/7 and you practise alone, out loud, whenever it suits you. No coordinating diaries, no waiting for a course date.
Is MedMock right for me if I am sitting the Renal Medicine ST4?
If your Renal Medicine ST4 interview involves speaking — thinking on your feet in front of a panel — then spoken rehearsal is exactly what MedMock is built for.
