Endocrine, Renal and Metabolic Emergencies
Interpret fluid, electrolyte, acid-base, glucose, renal and endocrine abnormalities in clinical context.
How to prepare for FRCEM SBA
Protect the full Emergency Medicine curriculum, prioritise the published item counts and practise the decisions expected of a clinician approaching independent practice.
Core concepts
Concept 1
Define the physiological disturbance, its cause, its tempo and whether correction itself creates risk.
Exam cue: Prioritise dangerous potassium disturbance, severe dysglycaemia, adrenal crisis, symptomatic sodium disorder, pulmonary oedema and dialysis indications.
Concept 2
Correct immediate threats with explicit rates, monitoring and stopping rules while treating the precipitant and involving renal or endocrine teams.
Exam cue: Use paired biochemical data, blood gas interpretation, ECG, volume assessment and serial response rather than isolated values.
Risk pitfalls and guardrails
Correcting a biochemical number too rapidly without accounting for chronicity, tonicity, renal function or treatment complications.
Guardrail: Do not select an option because it is technically true; select the one that best fits the patient's current physiology, evidence, urgency and decision point.
Choosing an answer that is generally true but does not fit the patient's physiology, urgency, evidence or current decision point.
Guardrail: Do not select an option because it is technically true; select the one that best fits the patient's current physiology, evidence, urgency and decision point.
Memory anchors
What frames decisions in endocrine, renal and metabolic emergencies?
Define the physiological disturbance, its cause, its tempo and whether correction itself creates risk.
Which endocrine, renal and metabolic emergencies findings change urgency?
Prioritise dangerous potassium disturbance, severe dysglycaemia, adrenal crisis, symptomatic sodium disorder, pulmonary oedema and dialysis indications.
How should investigation be planned in endocrine, renal and metabolic emergencies?
Use paired biochemical data, blood gas interpretation, ECG, volume assessment and serial response rather than isolated values.
What makes management complete in endocrine, renal and metabolic emergencies?
Correct immediate threats with explicit rates, monitoring and stopping rules while treating the precipitant and involving renal or endocrine teams.
What common error should be avoided in endocrine, renal and metabolic emergencies?
Correcting a biochemical number too rapidly without accounting for chronicity, tonicity, renal function or treatment complications.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A 24-year-old woman with type 1 diabetes has vomiting and abdominal pain. Glucose is 28 mmol/L, ketones 6.4 mmol/L, venous pH 7.12 and potassium 3.0 mmol/L. After starting intravenous isotonic fluid, what should happen before insulin infusion?
A 79-year-old woman with type 2 diabetes is confused and profoundly dehydrated. Glucose is 49 mmol/L, measured osmolality 342 mOsm/kg, ketones 0.7 mmol/L and pH 7.36. Which initial treatment is most appropriate?
