The nurse is caring for a client with severe diarrhea. The nurse recognizes that the client is at risk for developing which acid-base imbalance? Respiratory acidosis Metabolic alkalosis Metabolic acidosis Respiratory alkalosis

ANS: Metabolic acidosis

Which set of arterial blood gas (ABG) results requires further investigation? pH 7.49, PaCO2 30 mm Hg, PaO2 89 mm Hg, and HCO3- 18 mEq/L pH 7.35, PaCO2 40 mm Hg, PaO2 91 mm Hg, and HCO3- 22 mEq/L pH 7.44, PaCO2 43 mm Hg, PaO2 99 mm Hg, and HCO3- 26 mEq/L 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

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

When a client's ventilation is impaired, the body retains which substance? Oxygen Nitrous oxide Sodium bicarbonate Carbon dioxide

ANS: Carbon dioxide

Which could be a potential cause of respiratory acidosis? Diarrhea Vomiting Hypoventilation Hyperventilation

ANS: Hypoventilation

A client has a respiratory rate of 38 breaths/min. What effect does breathing faster have on arterial pH level? No effect Decreases arterial pH Increases arterial pH Provides long-term pH regulation

ANS: Increases arterial pH

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? pH, 7.40; PaCO2 35 mm Hg pH, 7.25; PaCO2 50 mm Hg pH, 7.35; PaCO2 40 mm Hg pH, 7.5; PaCO2 30 mm Hg

ANS: pH, 7.25; PaCO2 50 mm Hg
