HESI Med Surg Hematological system ( 54 Questions)
The given ABG results indicate a low pH (acidosis), an elevated PaCO2 (respiratory component), and a normal HCO3 (metabolic component) The low pH and increased PaCO2 suggest respiratory acidosis. The normal HCO3 indicates that the metabolic component is normal. This ABG profile is consistent with metabolic acidosis with respiratory compensation.
Metabolic alkalosis is characterized by an elevated pH and HCO3 levels. The given ABG results do not indicate metabolic alkalosis.
Respiratory acidosis is characterized by a low pH and an elevated PaCO2. While the patient does have an elevated PaCO2, the normal HCO3 levels indicate a metabolic component. This ABG profile is not consistent with pure respiratory acidosis.
Respiratory alkalosis is characterized by a high pH and low PaCO2. The given ABG results do not indicate respiratory alkalosis.
Choice A rationale:
The given ABG results indicate a low pH (acidosis), an elevated PaCO2 (respiratory component), and a normal HCO3 (metabolic component) The low pH and increased PaCO2 suggest respiratory acidosis. The normal HCO3 indicates that the metabolic component is normal. This ABG profile is consistent with metabolic acidosis with respiratory compensation.
Choice B rationale:
Metabolic alkalosis is characterized by an elevated pH and HCO3 levels. The given ABG results do not indicate metabolic alkalosis.
Choice C rationale:
Respiratory acidosis is characterized by a low pH and an elevated PaCO2. While the patient does have an elevated PaCO2, the normal HCO3 levels indicate a metabolic component. This ABG profile is not consistent with pure respiratory acidosis.
Choice D rationale:
Respiratory alkalosis is characterized by a high pH and low PaCO2. The given ABG results do not indicate respiratory alkalosis.
