[Ca2+]↓ in serum [K+]↓ in serum [Na+]↓ in serum [Cl-]↓ in serum 2/20 the pH of plasma is determined by? the ratio of [HCO3] and [H2CO3] PaCO2 BE [HCO3] 3/20 which kind of acid-base disturbance does the increased AG usually occurs in? metabolic acidosis metabolic acidosis with normal [Cl-] metabolic acidosis with increases [Cl-] resiratory acidosis 4/20 primarily decreased [HCO3-] can occurs in? metabolic acidosis respiratory alkalosis metabolic alkalosis metabolic alkalosis plus respiratory alkalosis 5/20 severe renal failure can induce? metabolic acidosis with increased [Cl-] metabolic alkalosis respiratory acidosis metabolic acidosis with normal [Cl-] 6/20 [HCO3-] secondarily decreased can occur in? metabolic acidosis respiratory acidosis metabolic alkalosis respiratory alkalosis 7/20 the acidic urine in alkalosis means? hyponatremia hypokalemia hypocalcemia hypochloraemia 8/20 the electrolytic changes in respiratory acidosis are? hypokalemia and hypochloraemia hyperkalemia and hypochloraemia hyperkalemia and hyperchloraemia hypokalemia and hyperchloraemia 9/20 metabolic acidosis with increased AG can induced by? severe diarrhea overdoes of normal saline uncontrolled diabetes mellitus hyperkalemia 10/20 a patient with high fever has a laboratory as follows: pH 7.55 PaCO2 30 mmHg AB 23 mmol/L BE 1mmol/L SB24 mmol/L the diagnosis should be? metabolic alkalosis metabolic acidosis acute respiratory alkalosis chronic respiratory alkalosis 11/20 renal tubular acidosis can lead to? metabolic acidosis with normal [Cl-] metabolic acidosis with increased [Cl-] respiratory acidosis metabolic alkalosis 12/20 PaCO2 primarily increased can occur in? metabolic acidosis respiratory alkalosis respiratory acidosis metabolic alkalosis 13/20 hysteria can lead to? metabolic acidosis respiratory alkalosis respiratory acidosis metabolic alkalosis 14/20 metabolic acidosis with normal AG occurs in? shock severe diarrhea severe hypoxia uncontrolled diabetic mellitus 15/20 which is the best parameter that can reflect respiratory status in the body? PaCO2 pH SB BB AB 16/20 which kind of mixed acid-base disturbance does patient impossible develop? respiratory acidosis plus metabolic alkalosis respiratory acidosis plus respiratory alkalosis metabolic acidosis plus respiratory alkalosis metabolic acidosis plus metabolic alkalosis 17/20 the difference of parameters btween acute respiratory acidosis and chronic respiratory acidosis mainly induced by? buffering in ECF respiratory compensation renal compensation buffering in ICF 18/20 a patient with shock has a laboratory test as follows: pH 7.30PaCO2 30 mmHg AB 16 mmol/L BE -6 mmol/L the diagnosis should be? metabolic acidosis respiratory alkalosis metabolic alkalosis acute respiratory acidosis 19/20 cardiopulmonary arrest can usually lead to? metabolic acidosis respiratory acidosis metabolic alkalosis metabolic acidosis plus respiratory acidosis metabolic alkalosis plus respiratory acidosis 20/20 the buffering in ECF of metaboic acidosis can lead to? AB ↑ [HCO3-] ↑ HCO3- consumed PaCO2 ↑
