explain metab acidosis differentials
idk if this is really within scope
- introduce self
- check student's identity and level of experience
- ensure patient (if applicable) is safe in department
- set learning objectives
- explain how to calculate anion gap
- explain confounding factors
- extremes of albumin (high/low) → high anion gap without acidosis can be caused by high albumin
- normal anion gap + metab acidosis implies loss of HCO3
- details possible causes: addisons, GI/renal losses, diuretics (acetazolamide)
- high anion gap + metab acidosis
- contextualise to patient
- elicit questions
- signpost to further learning material
