Endocrinology and Nephrology
Interpret endocrine, renal, electrolyte and acid-base abnormalities in emergency presentations.
How to prepare for MRCEM SBA
Build clinical synthesis across stable adult care, resuscitation, injury, paediatrics, procedures and complex decisions while preserving the full RCEM clinical-syllabus breadth.
Core concepts
Concept 1
Diabetes, adrenal and thyroid disease, calcium disorders, acute kidney injury, chronic kidney disease, sodium and potassium disorders, fluid balance and acid-base.
Exam cue: Identify diagnosis, investigation, immediate treatment, longer management, disposition or professional action in the lead-in.
Concept 2
Use clinical volume state, paired laboratory results, trends and medicines to identify mechanism and treatment priority.
Exam cue: Use acuity, age, physiology, time course, comorbidity and response to treatment to rank plausible options.
Concept 3
Recognise hyperkalaemia, severe dysnatraemia, adrenal crisis, diabetic emergency and indications for urgent renal support.
Exam cue: Choose the single fully correct action at this point in care and know when senior, specialty or critical-care escalation is required.
Concept 4
Use the current Year 1-3 RCEM capabilities and the full clinical syllabus at the understanding-and-applying level expected before higher specialist training.
Risk pitfalls and guardrails
Correcting a number without identifying chronicity, compartment, renal handling, endocrine driver and safe rate of change.
Guardrail: Do not choose an option merely because it is true; select the one that fits the exact patient, urgency and time point.
Choosing a true statement that does not answer the exact time point or clinical task.
Guardrail: Do not choose an option merely because it is true; select the one that fits the exact patient, urgency and time point.
Inventing a paper-specific or subcategory weighting that RCEM has not published.
Guardrail: Do not choose an option merely because it is true; select the one that fits the exact patient, urgency and time point.
Memory anchors
Endocrinology and Nephrology: scope
Diabetes, adrenal and thyroid disease, calcium disorders, acute kidney injury, chronic kidney disease, sodium and potassium disorders, fluid balance and acid-base.
Endocrinology and Nephrology: clinical synthesis
Use clinical volume state, paired laboratory results, trends and medicines to identify mechanism and treatment priority.
Endocrinology and Nephrology: safety boundary
Recognise hyperkalaemia, severe dysnatraemia, adrenal crisis, diabetic emergency and indications for urgent renal support.
Endocrinology and Nephrology: common trap
Correcting a number without identifying chronicity, compartment, renal handling, endocrine driver and safe rate of change.
Endocrinology and Nephrology: MRCEM SBA sequence
Identify the clinical task and acuity, synthesise history, examination and investigations, choose the safest evidence-based decision, then check disposition and escalation.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
