A patient has blood chemistries listed below. Patient Values pH = 7.25 PCO2 = 60 mmHg PaO2 = 20 mmHg [HCO-3] = 15 mM serum base excess = 0 [Na+] = 143 mM [K+] = 4 mM [Cl-] = 107 mM [Ca2+] + [Mg2+] = 3 mM [other anions] = 1 mM [protein] = 6.5 g/dL Osm = 286 mOsm/kg Normal values pH = 7.35-7.45 PCO2 = 38-42 mmHg PaO2 = >90 mmHg [HCO-3] = 23-26 mM serum base excess = -2 to +2 [Na+] = 134-146 mM [K+] = 3.5-5.1 mM [Cl-] = 92-109 mM [Ca2+] + [Mg2+] = 3-4 mM [other anions] = 1-2 mM [protein] = 5.6-8.4 g/dL Osm = 274-296 mOsm/kg a) What type of disturbance does this person have? Briefly explain the nature and possible cause of the disturbance. (HINT: a balance diagram may be helpful and not all of the given values may be needed)
