Questions and Answers

What is one of the mechanisms by which smoke inhalation leads to the development of emphysema?

  • Destruction of alveolar walls (correct)
  • Enhanced elastic recoil of the lungs
  • Increased production of mucus in the airways
  • Improved airflow during expiration

Which symptom is most indicative of chronic obstructive pulmonary disease (COPD) in the elderly?

  • Chronic cough (correct)
  • Increased appetite
  • Frequent headaches
  • Rapid weight gain

What is one possible consequence of a 40-year smoking history on lung function?

  • Reversal of previous lung damage
  • Development of irreversible airflow limitation (correct)
  • Increased lung capacity
  • Improvement in respiratory muscle strength

Study Notes

Patient Presentation

  • 90-year-old female patient.
  • Complaining of increased breathlessness (dyspnea) over the past 6 months.
  • 40-year history of smoking (10 cigarettes/day).
  • GP suspects Chronic Obstructive Pulmonary Disease (COPD).
  • Smoke inhalation causes lung damage leading to emphysema. The specific mechanism by which smoke causes damage to the lungs leading to emphysema is not stated.

Patient Presentation

  • 90-year-old female patient.
  • Complaining of increased breathlessness over the past six months.
  • 40-year history of smoking (10 cigarettes/day).
  • Physician suspects Chronic Obstructive Pulmonary Disease (COPD).

Emphysema Pathophysiology (due to smoke inhalation):

  • Smoke inhalation causes damage to the lungs in multiple ways.
  • One mechanism is the destruction of alveolar walls.
  • This results in fewer, larger alveoli, reducing the surface area for gas exchange.
  • This leads to the characteristic air trapping and reduced expiratory airflow in emphysema.
