Question

1. when lung tissue swells as a result of distention and loss of elasticity in the alveoli, the condition is called:

croup
asthma
pertussis
emphysema

1. colds are treated symptomatically, which means:

symptoms are unobservable
symptoms run their course
symptoms are ignored
symptoms are treated with medications

Explanation:

Question 13

• Croup is a respiratory infection affecting the larynx, trachea, and bronchi, not related to alveolar distention.
• Asthma is a chronic inflammatory disease with airway constriction, not alveolar elasticity loss.
• Pertussis (whooping cough) is a bacterial infection causing severe coughing, not alveolar issues.
• Emphysema is a lung condition where alveoli are damaged, leading to distention, loss of elasticity, and lung tissue swelling.

• "Symptoms are unobservable" is incorrect; cold symptoms are observable.
• "Symptoms run their course" means letting the illness resolve without targeted treatment, but symptomatic treatment involves addressing symptoms.
• "Symptoms are ignored" is wrong; symptomatic treatment addresses symptoms.
• "Symptoms are treated with medications" is correct for symptomatic treatment (e.g., using decongestants for nasal congestion in colds).

Answer:

D. emphysema
