Answers:
Bilirubin = 107 umol/L. That is elevated.
Bilirubin gets elevated either due to increase production or reduced elimination (Like any other substance in the body). That can be caused by a malfunction in any of the three phases of bilirubin production.
Question 1:
PH = 7.23, that is moderate acidaemia.
pCO2 = 62 mmHg, S we have respiratory acidosis, this can be acute or chronic.
87 year old man with history of COPD and type 2 DM on insulin and metformin, was found unconscious. His VBG showed the following.
PH = 7.23
pCO2 = 62 mmHg
80 year old man presented with shortness of breath. This patient had history of CHF and COPD. His venous blood gases showed the following
Question 1:
PH = 7.299 that is mild acidaemia
pCO2 = 80 mmHg, So we have metabolic acidosis. Next we need to calculate the compensation.
77 year old lady referred by GP for shortness of breath on exertion. Her venous blood gases showed the following:
PH = 7.299
pCO2 = 80 mmHg
Question 1:
For synovial fluid analysis. WBC level more than 50,000 (especially if more than 80,000) is suggestive of septic arthritis.
60 year old man with painful knee effusion. Synovial fluids analysis showed the following:
Question 1:
PH = 7.19, that is severe acidaemia.
HCO3 = 14 mmol/L, So we have metabolic acidosis. Next, we need to calculate respiratory compensation and anion gap.
