Explanation
Answer: d. Preventing complications of hypoxia
Explanation: Oxygen therapy is indicated in clients with COPD to prevent complications of hypoxia, such as tissue damage and respiratory failure.
Incorrect choices: a. Maintaining oxygen saturation above 95% is not the primary indication for oxygen therapy in clients with COPD. Target oxygen saturation levels may be lower due to the risk of suppressing the respiratory drive.
b. Correcting underlying lung pathology may require other interventions but does not solely indicate oxygen therapy.
c. Relieving shortness of breath may be a beneficial outcome of oxygen therapy, but it is not the primary indication in this case.
