Interferon gamma release essay (IGRA)

Question 18

This is a chronic resp. disease consisting of recurrent episodes of dyspnea, coughing, and wheezing leading to bronchial inflammation and muscle contraction

Answer 18

asthma

Question 19

what is the most common type of asthma?

Answer 19

extrinsic (allergic or atopic): allergic triggers from outside the body

Question 20

this is an exaggerated inflammatory response triggered by inhalation of an environmental allergen such as dust pollen, or smoke

Answer 20

extrinsic asthma

Question 21

the triggers of this asthma is emotional stress, GERD, obesity..usually seen inadults

Answer 21

intrinsic

Question 22

what does COPD stand for?

Answer 22

chronic obstructive pulmonary disorder

Question 23

what are the two most common types of COPD?

Answer 23

emphysema and chronic bronchitis

Question 24

what is the physiology of the respiratory system?

Answer 24

Respiratory tract from nasal cavity to lungs/passageway for air exchg.
- Fresh air inhaled in the nasal cavity into lungs
- Exhaled air contains carbon dioxide (air that leaves the body)
- Gas exchange (at the cellular level) occurs in the alveoli at ends of bronchioles
- Cardiovascular system works w/ the respiratory system to pump oxygenated bl.
from lungs to all cells in the body and deoxygenated bl. back to the lungs.

Question 25

what are the categories of respiratory assessment?

Answer 25

A. Vital Signs
B. Spirometry (p. 1111)
C. Pulse Oximetry (test that measures Oxygen saturation levels)
D. Chest X-ray (ck. for radiopacities in the lungs)
E. Blood Gas Analysis
F. Cytology (body cells and fluids) to determine the presence of microorganisms.

Question 26

how does TB develop?

Answer 26

• Inhaled tubercle bacilli travel to the lung where the infection begins.
• TB can affect any organ but M. tuberculosis can survive in high oxygen, such as the lungs.

Question 27

what types of oral manifestations occur with TB?

Answer 27

Occurs in the oral cavity from pulmonary organisms in infected sputum brought on by coughing.

• Classic lesion-painful, deep, irregular ulcer (Fig. 66-5, p. 1118.)
• You can also find lesions on the palate, lips, bm, and gingiva.
• A biopsy confirms dx. of TB.
• Glandular swelling in cervical and submand. Lymph nodes can be affected w/ TB.

Question 28

What are the types of asthma?

Answer 28

A. Extrinsic (allergic or atopic): allergic triggers from outside the body.
B. Intrinsic (non-allergic): non-allergic triggers from within the body.
C. Drug- or food-induced (non-allergenic, non-atopic).
D. Exercised-induced: vigorous physical activity.
E. Infection-induced: lung infections caused by viruses, bacteria, or fungi.

Question 29

what is one of the five types of antibodies produced by the body

Answer 29

IgE

Question 30

IgE breaks down the allergens and removes them from the body. Normally, this activity does not produce noticeable symptoms.

Answer 30

normal inflammatory reaction

Question 31

People with asthma are believed to “hyperreact” and produce more IgE antibodies than normal. This can result in symptoms of asthma: wheezing, coughing, dyspnea.

Answer 31

asthmatic hypersensitivity reaction

Question 32

what are the oral manifestations of asthma?

Answer 32

 Beta-2 agonist inhalers cause a decrease in salivary flow
 Dental biofilm pH and are associated with xerostomia and a possible increase in caries and gingivitis in patients.
 Increase in gastroesophageal reflux disease (GERD) with use of beta-2 agonists and theophylline, which may contribute to enamel erosion.
 Oral candidiasis may occur with high dosage or frequency of inhaled corticosteroids.
 Occurrence may decrease with use of a “spacer” or aerosol-holding chamber attached to metered-dose inhaler and rinsing mouth with water after each use.

Question 33

described as a widening of the airways destroying the alveolar walls of the bronchioles.

Answer 33
