Emphysema
Post-Test for Emphysema
Jennifer Kong
- True
- False
2. Repeated injury to the lungs, via inhaled irritants, will stimulate what response? Select all that apply.
- Recruitment of leukocytes to the lung tissue with the inhaled irritant
- Promotion of alveolar cell growth in size
- Remodelling of elastin-containing lung tissue into non-elastic fibrous tissue
- Increased production of elastin in lung tissue to trap inhaled irritants
- Decreased production of mucous to allow for easier inhalation
3. Fill in the blanks.
“Barrel chest” in emphysema develops because there is an _____ in chest volume. The chest volume is determined by alveolar air space which has _____ due to coalescing of alveolar air space after _____ is destroyed. In addition, the bronchioles have become _____ due to _____ production and loss of _____ thus making it easier to collapse and close during _____. The result is air trapping which progressively _____ the lung & chest volume, yet the actual amount of exhaled volume _____.
4. Fill in the blanks with the following words:
hypercapnia, weight loss, productive cough, fatigue, cyanosis, wheezing
_____ and _____ occurs when insufficient gas exchange occurs at the alveoli. _____ is felt when there is a decrease in oxygenated blood in circulation. _____ and _____ occur due to narrowed airways blocking air flow out during exhalation. _____ occurs due to the increased work of breathing.
Answer Key
1. False
2. Recruitment of leukocytes to the lung tissue with the inhaled irritant, remodelling of elastin-containing lung tissue into non-elastic fibrous tissue
3. Increase, increased, alveolar wall, narrowed, mucous, elastin, exhalation, increases, decreases
4. Cyanosis, hypercapnia, fatigue, wheezing, productive cough, weight loss
