ABG Quiz

The nurse is caring for a client who is in respiratory distress. The physician orders arterial blood gases (ABGs) to determine various factors related to blood oxygenation. What site can ABGs be obtained from? A. A puncture at the radial artery B. The trachea and bronchi C. The pleural surfaces D. A catheter in the arm vein

A. A puncture at the radial artery

A client who is being treated for pneumonia reports sudden shortness of breath. An arterial blood gas (ABG) is drawn. The ABG has the following values: pH 7.21, PaCO2 64 mm Hg, HCO3 = 24 mm Hg. What does the ABG reflect? A. Respiratory acidosis B. Metabolic alkalosis C. Respiratory alkalosis D. Metabolic acidosis

A. Respiratory acidosis

A. pH B. PaCO2 C. HCO3

A client has the following arterial blood gas (ABG) values: pH, 7.12; partial pressure of arterial carbon dioxide (PaCO2), 40 mm Hg; and bicarbonate (HCO3-), 15 mEq/L. These ABG values suggest which disorder? A. Metabolic alkalosis B. Metabolic acidosis C. Respiratory alkalosis D. Respiratory acidosis

B. Metabolic acidosis

B. pH 7.49, PaCO2 30 mm Hg, PaO2 89 mm Hg, and HCO3- 18 mEq/L

A nurse reviews the arterial blood gas (ABG) values of a client admitted with pneumonia: pH, 7.51; PaCO2, 28 mm Hg; PaO2, 70 mm Hg; and HCO3--, 24 mEq/L. What do these values indicate? A. Metabolic alkalosis B. Respiratory acidosis C. Respiratory alkalosis D. Metabolic acidosis

C. Respiratory alkalosis

A client with Guillain-Barré syndrome develops respiratory acidosis as a result of reduced alveolar ventilation. Which combination of arterial blood gas (ABG) values confirms respiratory acidosis? A. pH, 7.5; PaCO2 30 mm Hg B. pH, 7.40; PaCO2 35 mm Hg C. pH, 7.35; PaCO2 40 mm Hg D. pH, 7.25; PaCO2 50 mm Hg

D. pH, 7.25; PaCO2 50 mm Hg

The nurse is analyzing the arterial blood gas (ABG) results of a client diagnosed with severe pneumonia. Which of the following ABG results indicates respiratory acidosis? A. pH: 7.40, PaCO2: 40 mm Hg, HCO3-: 24 mEq /L B. pH: 7.50, PaCO2: 30 mm Hg, HCO3-: 24 mEq/L C. pH: 7.32, PaCO2: 40 mm Hg, HCO3-: 18 mEq/L D. pH: 7.20, PaCO2: 65 mm Hg, HCO3-: 26 mEq/L
