Question 1 of 5
A nurse is analyzing the ABG results of a client who is in respiratory acidosis. Which of the following mechanisms should the nurse identify as responsible for this acid-base imbalance?
Correct Answer: A
Rationale: The correct answer is A: Retention of carbon dioxide. In respiratory acidosis, there is an excess of carbon dioxide (CO2) in the blood, leading to a decrease in pH. This imbalance occurs when the lungs are unable to eliminate enough CO2 through respiration, causing it to accumulate in the bloodstream. This excess CO2 combines with water in the blood to form carbonic acid, leading to acidosis.
Choices B, C, and D are incorrect as they do not directly relate to the accumulation of CO2 in respiratory acidosis. Loss of bicarbonate (
B) would lead to metabolic acidosis, excessive vomiting (
C) would cause metabolic alkalosis, and hyperventilation (
D) would actually help in decreasing CO2 levels, which is not the case in respiratory acidosis.
