Diabetes and Metabolic Emergencies
Manage diabetic emergencies and individualise long-term glucose, vascular, renal, retinal and foot care.
How to prepare for MRCP(UK) Part 2 Written
Use the official likely question distribution to protect breadth, then practise extracting decisive clinical and visual evidence before selecting one best answer.
Core concepts
Concept 1
Glucose, ketones, acid-base or osmolality, fluid state, potassium, precipitant and treatment history.
Exam cue: DKA, HHS, severe hypoglycaemia, dangerous potassium change or treatment-related cerebral or cardiac risk.
Concept 2
Coordinate fluids, insulin, electrolytes and trigger treatment, then individualise prevention and complication review.
Exam cue: Use repeated biochemical and physiological measures to confirm the syndrome and judge resolution.
Risk pitfalls and guardrails
Treating glucose alone while overlooking potassium, osmolality, volume state or the precipitating illness.
Guardrail: Do not select an option merely because it is true; choose the one that best fits the exact clinical task, urgency and time point.
Selecting an option that is true in isolation but does not best answer the exact clinical task.
Guardrail: Do not interpret a visual pattern without the modality, clinical context and the exact task in the stem.

Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
