25 year old male presents to ED feeling generally unwell. He complains that he is feeling weak and has been unable to complete his gym workouts recently. He has no background history, and denies any current medication or illicit drug use. He is a professional body builder.  O/E Vitals normal limits. Very muscular physique, marked acne on his back. VBG:

  1. Describe and interpret the VBG
  2. What performance enhancing drugs should be considered when assessing body builders and what complications can these drugs cause?

  1. Impression: Highly suspicious for stanozolol abuse. Would consider other anabolic steroids as alternative explanation.

    Metabolic alkalosis with severe hypokalemia. Slightly reduced chloride.
