Residents with chronic obstructive pulmonary disease (COPD) primarily have trouble with?

Residents with chronic obstructive pulmonary disease (COPD) primarily have trouble with breathing due to the nature of the disease. COPD is a progressive respiratory condition that encompasses primarily emphysema and chronic bronchitis, both of which lead to obstructed airflow from the lungs. As a result, individuals with COPD experience symptoms such as shortness of breath, wheezing, and chronic coughing. The condition affects the ability to effectively exchange gases, leading to difficulties in obtaining enough oxygen and properly expelling carbon dioxide during respiration.

Other options like urination, losing weight, or vision do not directly relate to the primary effects of COPD. While it's true that individuals with COPD may experience weight changes or complications affecting their overall health, the fundamental issue remains their compromised lung function, which directly impacts their ability to breathe.
