Question 1 of 5
The following arterial blood gas results would demonstrate to the nurse that the client is experiencing which acid-base imbalance? pH 7.31 PaCO2 40,HCO3 18 pa02 92
Correct Answer: D
Rationale: The given ABG results show a low pH (acidosis), low HCO3 (metabolic component), and normal PaCO2 (compensated respiratory component). This indicates a metabolic acidosis with respiratory compensation. The low HCO3 is the primary indicator of the metabolic acidosis. The normal PaCO2 suggests the respiratory system is compensating by decreasing ventilation to retain CO2 and increase pH.
Choices A, B, and C can be eliminated as they do not match the ABG results provided.
Choice D is correct as it aligns with the low pH and HCO3 levels, indicating metabolic acidosis with respiratory compensation.
