Which term describes a chronic, progressive, incurable lung disease that causes difficulty breathing?

• A. COPD
• B. Contracture
• C. CHF
• D. Converting measures

Answer: (A)

COPD, or chronic obstructive pulmonary disease, is a chronic, progressive lung disease where airflow is limited and breathing becomes increasingly difficult. It is not curable, but treatments can relieve symptoms and slow progression. This description fits because it emphasizes a long-lasting, worsening lung condition that causes trouble breathing.

In practice, CNAs support care by watching for increasing shortness of breath, changes in oxygen saturation, or color changes, and by helping position the patient to improve breathing (often sitting up or in a semi‑upright position). They also assist with energy conservation during activities, encourage prescribed breathing exercises or coughing techniques, and ensure medications and prescribed oxygen are used correctly and safely. Report any signs of respiratory distress promptly so the care team can respond.

Other terms listed don’t describe a chronic lung disease: a contracture is a joint tightness limiting movement; CHF is heart failure that can cause breathing trouble but is a heart condition, not a lung disease; and converting measures is not a medical term describing a lung condition.
