ABG practice questions
A client admitted with acute anxiety has the following arterial blood gas (ABG) values: pH, 7.55; partial pressure of arterial oxygen (PaO2), 90 mm Hg; partial pressure of arterial carbon dioxide (PaCO2), 27 mm Hg; and bicarbonate (HCO3-), 24 mEq/L. Based on these values, the nurse suspects: A.Respiratory alkalosis B.Respiratory acidosis C.Metabolic acidosis D.Metabolic alkalosis
A. Respiratory alkalosis
The nurse is assessing the following ABG 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
When evaluating arterial blood gases (ABGs), which value is consistent with metabolic alkalosis? A. HCO 21 mEq/L B. pH 7.48 C. PaCO 36 D. O saturation 95%
B. pH 7.48
Which set of arterial blood gas (ABG) results requires further investigation? A. pH 7.38, partial pressure of arterial carbon dioxide (PaCO2) 36 mm Hg, partial pressure of arterial oxygen (PaO2) 95 mm Hg, bicarbonate (HCO3-) 24 mEq/L B. pH 7.49, PaCO2 30 mm Hg, PaO2 89 mm Hg, and HCO3- 18 mEq/L C. pH 7.44, PaCO2 43 mm Hg, PaO2 99 mm Hg, and HCO3- 26 mEq/L D. pH 7.35, PaCO2 40 mm Hg, PaO2 91 mm Hg, and HCO3- 22 mEq/L
B. pH 7.49, PaCO2 30 mm Hg, PaO2 89 mm Hg, and HCO3- 18 mEq/L
Which arterial blood gas (ABG) result would the nurse anticipate for a client with a 3-day history of vomiting? A. pH: 7.55, PaCO2: 60 mm Hg, HCO3-: 28 B. pH: 7.45, PaCO2: 32 mm Hg, HCO3-: 21 C. pH: 7.28, PaCO2: 25 mm Hg, HCO3: 15 D. pH: 7.34, PaCO2: 60 mm Hg, HCO3: 34
C. pH: 7.28, PaCO2: 25 mm Hg, HCO3: 15
A patient with a neurological disorder 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
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.Respiratory alkalosis B.Respiratory acidosis C.Metabolic acidosis D.Metabolic alkalosis
