The client is experiencing respiratory acidosis as a result of COPD is likely to present with which of the following clinical signs? (Select 4 options that apply)

Rationale: A. Dysrhythmias may occur due to increased CO₂ levels and acid-base imbalance affecting cardiac conduction. B. Barrel chest is a common physical finding in clients with chronic COPD due to air trapping and lung hyperinflation. C. Difficulty arousing the client may indicate CO₂ narcosis, a sign of worsening respiratory acidosis. D. Confusion and disorientation, such as repeatedly asking "Where am I?", are neurological signs of elevated CO₂ levels. E. Deep, rapid respirations (Kussmaul respirations) are typical of metabolic acidosis, not respiratory acidosis from COPD.
