Canadian Practical Nurse Registration Examination (CPNRE) Practice Exam

Question: 1 / 595

Chronic Obstructive Pulmonary Disease (COPD) can lead to which of the following?

Severe allergic reactions

Acute lung infection

Barrel chest

Chronic Obstructive Pulmonary Disease (COPD) can lead to barrel chest as a result of long-term changes in the lungs and thoracic cavity. In COPD, particularly emphysema, the air sacs in the lungs become damaged, which causes the lungs to become hyperinflated. Over time, this hyperinflation can lead to structural changes in the chest wall. The rib cage may take on a rounded appearance, resembling a barrel, due to the chronic over-expansion of the lungs. This phenomenon is often accompanied by a paradoxical movement of the diaphragm and can lead to further complications in respiratory function.

Barrel chest is therefore a notable clinical manifestation in patients with advanced COPD, distinguishing it from the other conditions listed. Severe allergic reactions, acute lung infections, and anemia, while relevant to a broader healthcare context, are not direct resultants of COPD in the way barrel chest is.
