Question 13 - Single Best Answer
A 12 year old white male presents with a history of wheezing and a cough. He also has diarrhea. Several other family members have had the same symptoms at one time or another. On physical exam, he has wheezing, clubbing of the fingers and toes(this is found in patients who have chronic lung disease), and nasal polyps. Because of his family history, cystic fibrosis is suspected. It is an autosomal recessive disease in which there is thick, copious secretions with increased amount of chloride ion. A sweat test is done. The chloride is 200 mEq/L(normal is <60 mEq/ L). Which structure would help to clear mucous from the airway?
A) goblet cell
B) cilia
C) dust cell
D) type II pneumocyte
Question 14 - Single Best Answer
Cultures of his sputum grew Staphylococcus aureus and Pseudomonas aeruginosa(bacteria). These microorganisms are usually found in the lungs of these patients. They cause inflammation of the lungs(pneumonia). Which item plays a direct role in the prevention of alveolar collapse?
A) surfactant
B) mucous
C) good air movement in the lungs
D) eating "Wheaties"
Question 15 - Single Best Answer
Asthmatics also wheeze. It is a phenomenon that occurs when the size of the airway decreases. With the patient above, mucous plugs are the cause. In asthmatics, there is smooth muscle contraction that decreases airway size along with inflammation/mucous. Which of the following is least likely to be affected during an asthmatic attack?
A) bronchi
B) bronchiole
C) alveoli
Question 16 - Single Best Answer
Emphysema is a lung disease which tends to occur after many years of smoking cigarettes. It is manifested as shortness of breath because the lung parenchyma is destroyed and therefore there are changes in alveolar volume. Which depicts emphysema?
