Interpretation of the Arterial Blood Gas

The solution that would be most alkalotic would be the one would be the one with a pH of: A. Four B. Seven C. Nine D. Fourteen The normal pH range for blood is: A. 7.0-7.25 B. 7.30-7.40 C. 7.35-7.45 D. 7.45-7.55 The respiratory system compensates for changes in the pH level by responding to changes in the levels of: A. CO2 B. H2O C. H2CO3 D. HCO3 The kidneys compensate for acid-base imbalances by excreting or retaining: A. Hydrogen ions B. Carbonic acid C. Sodium bicarbonate D. Water All of the following might be a cause of respiratory acidosis except: A. Sedation B. Head trauma C. COPD D. Hyperventilation A answer- A patient with a prolonged episode of nausea, vomiting and diarrhea has an ABG ordered on admission. You might expect the results to show: A. Metabolic acidosis B. Metabolic alkalosis C. Respiratory acidosis D. Respiratory alkalosis A calculated ABG value that indicates excess of insufficiency of sodium bicarbonate in the system is: A. HCO3 B. Base excess C. PaO2 D. pH Which of the following may be a reason to order an ABG on a patient? A. The patient suddenly develops shortness of breath B. An asthmatic is starting to show signs of tiring C. A diabetic has developed Kussmaul respirations D. All of the above You are reviewing the results of an ABG. When the pH and the PaCO2 values are moving in opposite directions, the primary problem is: A. Respiratory B. Renal C. Metabolic D. Compensation When an acid-base imbalance is caused by a metabolic disturbance, the pH and the HCO3 will move: A. In opposite directions B. Totally independent of each other C. In the same direction The oxyhemoglobin dissociation curve represents the relationship between the: A. O2 saturation and hemoglobin level B. O2 saturation and PaO2 C. PaO2 and the HCO3 D. PaO2 and the pH On the normal oxyhemoglobin curve, if the O2 saturation is 88%, it would correlate with a PaO2 of approximately: A. 60mm Hg B. 80mm Hg C. 90mm Hg D. 100mm Hg pH 7.33 pCO2 60 HCO3 34 A.
