Answer : D
EHSAN

A. T10
4) in which of the following the occupational asthma is less likely :
A. bakery
B. metallic salts
2) Which of the following about pneumoconiosis is wrong :
A. X-Ray is the best way to diagnose it
B. caused by inhalation of organic dust
C. the comparison b/w two X-Rays is highly important for the diagnosis
D. caused by direct effect of inhaled dust on lung tissue
3) One of the following regarding BOOP is false :
Ans: it's associated with good prognosis, often healing within 2-8 months .
4) One of the following is not a fibrosing reaction of RPD :
Ans: Sarcoidosis
5) Which is false about Centriacinar emphysema :
Ans: Centriacinar is less common than panacinar
6)The least lung tumor associated with smoking is :
Ans: Adenocarcinoma
7) The paraneoplastic syndrome with hypercalcemia is associated with :
Ans: Squamous cell lung cancer
8) One of these doesn't cause chronic pneumonia :
-Histoplasma capsulatum
-MTB blastomyces
- Coccidioidomycosis
-Pseudomonas aeruginosa
9) Regarding atopic asthma, one statement is false :
Ans: associated with decreased levels of IgE
10) Which of the following organisms is responsible of acute exacerbation of
COPD :
Ans: Maroxella Catarrhalis
11) Which would not cause an Acute Exacerbations of COPD :
1. Streptococcus pneumoniae
2. Haemophilus influenzae
3. Moraxella catarrhalis
4. Pseudomonas aeruginosa
5. Streptococcus mutans
13- The latency period of pneumoconiosis is :
- 5 y
- 5 -10 y
- 10 -15
- 15-20 y
- >> 20 y
15- One of the following is true about pulmonary hypertension :
- Pulmonary circulation is normally of high resistance
- TGF-B signaling pathway plays a role in sporadic primary pulmonary hypertension
- The primary form is the most common form
- Plexiform lesion are characteristic of the primary (idiopathic) form
- A decrease in endothelin cause vasoconstriction and pulmonary hypertension
16- All might show interstitial pneumonia pattern except :
-Mycoplasma pneumonia
-Resp.syncitial virus
-Chlamydia
-Rickettsia
-Stap.aureus
17- All are features of asthma except :
- repeated immediate hypersensitivity and late phase reaction in lung
- intermittent and reversible airway obstruction
- chronic bronchial inflammation with eosinophils
- bronchial smooth muscle cell hypertrophy and hyperactivity
-atopic type show normal to decrease level of IgE
18- Reid index is used to confirming the diagnosis of :
chronic bronchitis
19- All are feature of restrictive lung disease except :
- decrease lung compliance
- increase in effort to breath
- damage to alveolar epithelium and vasculature leads to abnormalities in ventilation-perfusion
ratio and hypoxia
- X-ray will show canon ball pattern
- progression to respiratory failure, pulmonary hypertension is common in non-treated cases
20 - The main inflammatory pathogenesis in fibrosis in interstitial lung disease :
Ans: Macrophage
21- RB mutation is seen in :
-Small cell carcinoma
-Adenocarcinoma
-Squamous cell carcinoma
-Large cell carcinoma
-Adenosquamous carcinoma
22- The most common laryngeal carcinoma is :
-Squamous cell carcinoma
-Large cell carcinoma
-Lymphoma
-Adeoncarcinoma
23- One false about TB :
- once bacterimia develop in primary TB most patients would symptomatic
- the development of cell mediated immunity occurs approximately 3 week after exposure
- IFNγ release CD4+ T-cell is crucial in activating macrophage
- the genetic makeup of the individual may influence the course of the disease
- IL-12 , TNF and nitric oxide participate in killing the mycobacterium
24-ALL of the following are risk factor of aspiration causing hospital acquired
pneumonia except :
- abnormal swelling
- exaggerated gag reflex
-altered consciousness

-decrease gastric motility
25- Regarding asthma and COPD :
-asthma usually start in young while COPD in old
