A nurse is caring for a client whose arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The nurse should identify that the client is experiencing which of the following acid-base imbalances?
Correct Answer: B
Rationale: Low pH (7.3) and high PaCO2 (50 mm Hg) indicate respiratory acidosis from CO2 retention. Other imbalances do not fit.

Question 4 of 5
A nurse is caring for a client who has hypovolemic shock. Which of the following should the nurse recognize as an expected finding?
Correct Answer: B
