[{'content': 'If blood gas analysis reveal pH = 7.52, pCO = 30 ; pO2 = 105. This will be compensated by ? \nSelect and explain. \nA. Compensatory respiratory acidosis, B. Compensatory respiratory alkalosis, C. Compensatory metabolic acidosis, D. Compensatory metabolic alkalosis', 'role': 'user'}, {'content': 'Answer: C \nExplanation: First step\n\nDetermine whether it is acidosis or alkalosis\nIncrease in pH suggests alkalosis\nSecond step\nLook at CO2 or HCO3- to determine the cause\nDecreased PCO2 suggests respiratory alkalosis\nRespiratory alkalosis\nRespiratory alkalosis occurs because CO2 is blown off in excess equation shifts to left and H+ conc. decrease which leads to alkalosis.\nNow the kidneys compensate for this alkalosis by excreting more HCOO3-. This shifts the equation to right thus H+ conc. decreases.', 'role': 'assistant'}]
