2. Pulmonary Path-1

Question 1

A 43 year old man comes into the doctor’s office with a productive cough for the past 2 months. He has been producing a orangish sputum. If the microbiological test was positive for fungal ifection which test would be have been used?

A. KOH prep
B. PCR
C. Gram stain
D. Antibiotic sensitivity 
E. DNA detection 

RFA

Answer 1

ANS. A KOH is used for fungi

B. & E PCR & DNA detection- viral

C & D- Antibiotic sensitivity & Gram Stain- Bacteria

Question 2

A 48 year old women has a tissue sample taken from her bronchioles. Which cell type would be able to confirm the tissue was taken from the bronchioles?

A. Ciliated Columnar 
B. Goblet Cells
C. Clara Cells
D. Basal Cells 
E. Neuroendocrine cells 

RFA

Answer 2

ANS. C- Clara cells- would be found only in the epithelium of bronchioles

A. Ciliated columnar cells- are found in both the bronchi and the bronchioles so would not be able to be used to confirm the tissue belongs to the Bronchioles

B, D,E - are all cell type only found in Bronchi

Question 3

Which of the following is not a function/characteristic of Type II pneumocytes?

A. Produce surfactant 
B. Repair alveolar epithelium
C. Cover 95% of alveolar surface
D. Regenerate alveolar epithelium 
E. Site of gas exchange

SZ

Answer 3

Ans. C & E

95% of the alveolar surface is covered with Type I pneumocytes. This is the site of gas exchange.

Type II pneumoncytes produce surfactant and can repair and regenerate alveolar epithelium if there is damage.

Question 4

Which of the following in Pulmonary Function Test describes the volume of air exhaled with force following maximal inhalation?

A. Tidal Volume
B. Forced Vital Capacity 
C. Forced Expiratory Volume
D. Forced Expiratory Flow
E. Residual Volume

SZ

Answer 4

Ans. B Forced Vital Capacity

Forced expiratory volume is the volume of air exhaled with force over a given period of time (usually 1 second)

Question 5

A 55 year old male presents with SOB, barrel chest, and pursed lip breathing. He is diagnosed with emphysema. His condition involves damage to alveolar septae; what type of cells are responsible for producing type I pneumocytes? (MG)

A. Alveolar macrophages
B. Endothelial cells
C. Type II pneumocytes
D. Pleuripotent stem cells

Answer 5

C. Type II pneumocytes

regen both types I and II and repair respiratory epithelium

Question 6

Which acronym represents the spirometry value for the volume of air exhaled with force following maximal inhalation? (MG)

A. TLC
B. TV
C. RV
D. FVC
E. FEV
F. FEF

Answer 6

D. FVC

forced vital capacity
