    21 year old medical student (not me) is revising for his exams (seriously, its not me...) and keeps eating Liquorice. He has hypertension.

    ABGs

    elevated pH
    normal bicarbonate
    slightly low pCO2
    low K+


    what is going on there?

    Yes it contains aldosterone, explains the hypertension and low K - but wud he not have a metabolic alkalosis - low pCO2 doesnt make any sense?

    Its an exam question, not a real case, what are they getting at?

    Low pCO2 and alkalosis suggests hyperventilation - also from exam stress? I don't see an obvious unifying cause so two benign causes (liquorice for upBP and downK together with breathing for downCO2 and uppH) sounds like the sort of thing Oxford might do.

    You're unlikely to get anything so obtuse on ?Tuesday?. At worst, dropping a few marks on a horrible question won't stop you from passing.

    Exam situation aside, why were they doing an ABG on him anyway?

      I hate it when people write like this. [obv you were prob writing tongue in cheek]

      Why do people put a question mark in front of a fact.
      i.e rip roraringly infected person comes in and the clerking F1 uts
      "imp: ?sepsis ?cause. Refer medics"

      I was joking indeed, loads of people hate it

      I'm sure we've all heard the "? Dark ? cause, refer to medics" orthopod jokes

      Yeah it might be that he was hyperventilating you're right. So two causes of alkalosis, id expect a really high bicarbonate. It was actually on the exam, this year - I was just curious

      Thanks for your help though!
