Question

A patient who has difficulty breathing because of damage that previous years of smoking caused to his lungs most likely has which condition?

A. Chronic obstructive pulmonary disease (COPD)
B. Asthma
C. Pneumonia
D. Tuberculosis

Answer 1

A patient with breathing difficulties from smoking most likely has Chronic obstructive pulmonary disease (COPD), a lung condition resulting from damaged alveoli and decreased elasticity, causing shortness of breath and insufficient gas exchange.

Step-by-step explanation:

The patient with breathing difficulties due to damage from years of smoking most likely has Chronic obstructive pulmonary disease (COPD). COPD is a lung condition that includes diseases such as emphysema and chronic bronchitis. Previous tobacco use is the primary cause of COPD, leading to the breakdown of lung connective tissues and a decrease in alveolar elasticity. This results in trapped air in the lungs and impaired gas exchange, which can cause low oxygen levels and an excess of carbon dioxide in the blood.

Patients with COPD experience symptoms like shortness of breath, a chronic cough with phlegm, and difficulty performing activities such as climbing stairs. While there is no cure for COPD, quitting smoking can slow its progression, and treatments like inhaled bronchodilators and supplemental oxygen can help alleviate symptoms. In very severe cases, lung transplantation may be considered.
