Question 1 of 5
A patient has end-stage chronic obstructive pulmonary disease (COPD). Which acid-base imbalance would be predictable in a patient with COPD?
Correct Answer: A
Rationale: The correct answer is A: Respiratory acidosis. In COPD, there is impaired gas exchange leading to retention of carbon dioxide, causing respiratory acidosis. This is because the lungs cannot effectively eliminate CO2 due to airway obstruction and decreased lung function. Metabolic alkalosis (
C) is not typically associated with COPD, as it is more related to excess bicarbonate or loss of acid. Respiratory alkalosis (
B) would not be expected in COPD as it results from hyperventilation, leading to a decrease in CO2 levels. Metabolic acidosis (
D) is not a typical acid-base disorder in COPD, as it is more related to issues like renal failure or diabetic ketoacidosis.
