In a person with normal kidneys and normal lungs who has chronic metabolic acidosis, you would expect to find all of the following, compared with normal, except:: (A) Increased renal excretion of NH4Cl, (B) Decreased urine pH, (C) Decreased urine HCO3- excretion, (D) Increased plasma HCO3- concentration
Answer is D. Chronic metabolic acidosis : is, by definition, associated with Decreased HCO3- Increased excretion of NH4Cl occurs with renal compensation for the acidosis Respiratory compensation for the acidosis increases the ventilation rate, resulting in Decreased plasma Pco2.
