Which of the following conditions is most likely to explain his clinical course?
A 60-year-old man has a 90 pack year history of smoking. For the past 5 years, he has had a cough productive of copious amounts of mucoid sputum for months at a time. He has had episodes of pneumonia with Streptococcus pneumonia and E. coli cultured. His last episode of pneumonia is complicated by septicemia and brain abscess and he dies. At autopsy, his bronchi microscopically demonstrate mucus gland hypertrophy.
A. Squamous cell carcinoma B. Congestive heart failure C. Chronic bronchitis D. Bronchial asthma E. Centrilobular emphysema F. Panlobular emphysema G. Bronchiectasis
The answer to this is letter C. Based on the symptoms that the man has displayed, he had this condition before he died. He has shown that he had a persistent cough that sometimes lasted for months. There are two main reasons why some people are more prone to chronic bronchitis.
It is because of constantly being exposed to air pollution and smoking. The inflamed bronchial tubes usually come up with more mucus that will make it more difficult for people who have this condition to breathe. People who are also exposed to a lot of dust for an extended period of time may be more prone to acquiring this condition more than others.
Chronic bronchitis -(c) correct. chronic bronchitis is defined clinically as a person who has persistent cough with sputum production for at least 3 months in at least 2 consecutive years. air pollution and smoking are key causes for chronic bronchitis.(a) incorrect. though lung cancers are more common in persons who smoke, his findings are not explained by a mass lesion, and his symptoms have persisted for years.(b) incorrect. congestive heart failure will produce pulmonary edema, if it is primarily left heart failure. if severe, there can be rusty colored sputum.(e) incorrect. as a smoker, he is at risk for development of emphysema, but this does not explain his sputum production. sometimes, smokers have elements of both emphysema and chronic bronchitis.(g) incorrect. bronchiectasis is not a typically complication of smoking.
