RN Comprehensive online practice 2019 B with NGN ( 180 Questions)
A nurse is reviewing the ABG values of a client. The client has a pH of 7.2, PaCO2 of 60 mm Hg, and HCO3 of 25 mEq/L. The nurse should identify that the client has which of the following acid-base imbalances?
The client does not have respiratory alkalosis because respiratory alkalosis is characterized by a low PaCO2 (less than 35 mm Hg) and a high pH (greater than 7.45)
The client does not have metabolic alkalosis because metabolic alkalosis is characterized by a high HCO3 (greater than 26 mEq/L) and a high pH (greater than 7.45).
The client has respiratory acidosis because respiratory acidosis is characterized by a high PaCO2 (greater than 45 mm Hg) and a low pH (less than 7.35).
The client does not have metabolic acidosis because metabolic acidosis is characterized by a low HCO3 (less than 22 mEq/L) and a low pH (less than 7.35).
Respiratory acidosis.
Rationale:
- A. Incorrect. The client does not have respiratory alkalosis because respiratory alkalosis is characterized by a low PaCO2 (less than 35 mm Hg) and a high pH (greater than 7.45).
- B. Incorrect. The client does not have metabolic alkalosis because metabolic alkalosis is characterized by a high HCO3 (greater than 26 mEq/L) and a high pH (greater than 7.45). - C. Correct. The client has respiratory acidosis because respiratory acidosis is characterized by a high PaCO2 (greater than 45 mm Hg) and a low pH (less than 7.35).
- D. Incorrect. The client does not have metabolic acidosis because metabolic acidosis is characterized by a low HCO3 (less than 22 mEq/L) and a low pH (less than 7.35).
