Matching Respiratory Disease Symptoms to Names

Steps:

• Identify key symptoms for disease 1: persistent cough with blood, chest pain, unexplained weight loss—hallmarks of lung cancer.
• Identify key symptoms for disease 2: progressive shortness of breath, wheezing, barrel-shaped chest—hallmarks of emphysema.
• Compare to choices: only D pairs lung cancer with disease 1 symptoms and emphysema with disease 2 symptoms.
• Eliminate mismatches based on symptom profiles.

Why D is correct:

• Lung cancer features malignant growth causing hemoptysis and systemic effects; emphysema involves alveolar destruction leading to air trapping, per pulmonary pathology definitions.

Why the others are wrong:

• A: Emphysema lacks cancer's bloody cough; lung cancer doesn't match emphysema's hyperinflation.
• B: Chronic bronchitis emphasizes mucus hypersecretion, not cancer's tumors or emphysema's destruction.
• C: Lung cancer and chronic bronchitis both involve cough but miss emphysema's distinct dyspnea without infection focus.

Final answer: D
