Question 1 of 5
A nurse is reviewing the arterial blood gas values for a client. The nurse should recognize that the values indicate which of the following acid-base imbalances? pH: 7.56 PaCO2: 55 mmHg HCO3: 33 mEq/L
Correct Answer: A
Rationale: The correct answer is A: Metabolic Alkalosis. A pH of 7.56 indicates alkalosis. The elevated HCO3 level of 33 mEq/L suggests a metabolic component. The normal PaCO2 of 35-45 mmHg rules out respiratory compensation. Metabolic Alkalosis occurs when there is an excess of bicarbonate ions in the blood, leading to elevated pH levels.
Choices B, C, and D are incorrect because they do not align with the given values. Metabolic Acidosis is characterized by low pH and low HCO3 levels. Respiratory Alkalosis is indicated by low PaCO2 levels. Respiratory Acidosis is characterized by high PaCO2 levels.
