Question

1. emphysema causes shortness of breath and a:

○ chicken chest
○ pigeon chest
○ barreled chest
○ dyschondroplastic chest

1. the incubation period for influenza is from ____ to ____ days.

○ 3 to 7 days
○ 10 to 14 days
○ 1 to 3 days
○ 7 to 10 days

Explanation:

Question 41

Emphysema is a lung disease that affects the air sacs, leading to difficulty in breathing. A key physical change associated with emphysema is the development of a barrel - shaped chest. This is because the lungs become overinflated and the ribcage expands to accommodate the trapped air, resulting in a chest that looks like a barrel. Chicken chest (pectus carinatum) and pigeon chest (pectus excavatum) are congenital chest wall deformities, and dyschondroplastic chest is related to a different type of skeletal disorder, not emphysema.

The incubation period of influenza (the time from exposure to the virus to the appearance of symptoms) is typically 1 to 3 days. The other options (3 - 7, 10 - 14, 7 - 10 days) do not match the known incubation period for influenza.

Answer:

Barreled Chest
