For each set of the following biochemical and arterial blood gas parameters:
- a) Describe the abnormalities.
- b) Give one example of an associated clinical scenario.
Any reasonable scenario accepted that was both biochemically correct AND clinically likely.
Answer and interpretation
- Increased anion gap and normal anion gap metabolic acidosis with appropriate respiratory
- Clinical scenario – diabetic ketoacidosis with ketonuria or DKA with N saline resuscitation.
- Increased anion gap, metabolic alkalosis and respiratory alkalosis.
- Clinical scenario – salicylate overdose.
- Increased anion gap metabolic acidosis and metabolic alkalosis.
- Clinical scenario – acute renal failure with vomiting .
- Acute respiratory acidosis with metabolic alkalosis.
- Clinical scenario – acute respiratory failure in COAD (Acute on chronic respiratory failure.
- Acute respiratory alkalosis.
- Clinical scenario – Psychogenic hyperventilation.
