Ch 3 Respiratory System WB Self Test

The major function of the respiratory system is to

1) provide oxygen for the blood

2) remove oxygen from the body tissue

3) provide carbon dioxide to body tissue

4) remove carbon dioxide from the blood

1 and 4

The lower respiratory system consists of the

a. nasopharynx

b. trachea

c. oropharynx

d. larynx

b. trachea

The gas exchange in the lung takes place in the

alveoli

On full inspiration, the diaphragm projects at the level of the

10th posterior intercostal space

A device that can measure the pulmonary capillary wedge pressure, cardiac output, and central venous pressure is a

Swanz-Ganz catheter

The disease process that is characterized by the secretion of excessive viscous mucus is

cystic fibrosis

Lack of lung development in premature infants that is radiographically demonstrated as an air bronchogram is

hyaline membrane disease

Major radiographic signs are pulmonary overinflation, alterations in pulmonary vascularization, and bullae formation in

emphysema

The most common work-related ling disease is

silicosis

Pneumoconiosis demonstrates radiographically as

scattered nodules and pleural thickening

Granulomas represent

scarred lung tissue due to infection

Lung cancers originating in the glandular structures of the bronchial tree are known as

bronchial adenoma

A staphylococcal infection primarily in the bronchi or bronchiolar mucosa describes

bronchopneumonia

Pneumonia appears radiographically as a

opacification

Tuberculosis survives outside the host for a long time because of its

waxy coat

A disease of the lung caused by fungus is

pulmonary mycosis

As a result of epithelial necrosis, the radiograph demonstrates an interstitial pneumonia in cases of

respiratory syncytial virus

If and upright image cannot be obtained, what other position or view would demonstrate pleural effusion?

lateral decub

Which of the following chest pathologies requires an decrease in technical factors from a "normal" chest radiograph?

a.atelectasis

b.pleural effusion

c.pneumonia

d.pneumothorax

d. pneumothorax

Which of the following chest pathologies requires an increase in technical factors from a "normal" chest radiograph?

a.atelectasis

b.pulmonary edema

c.pneumonia

d.pneumothorax

b.pulmonary edema

Which of the following respiratory pathologies is not associated with chronic obstructive pulmonary disease?

a.asthma

b.bronchitis

c.emphysema

d.croup

d.croup

Croup is

a viral infection of the subglottis

High-resolution CT has replaced V/Q scans in diagnosing

a.pulmonary edema

b.pulmonary effusion

c.pulmonary emboli

d.pulmonary mycosis

c.pulmonary emboli

A filling defect seen in the pulmonary artery is indicative of

a.pulmonary edema

b.pulmonary effusion

c.pulmonary emboli

d.pulmonary mycosis

c.pulmonary emboli

The abnormal connection between the pulmonary arteries and veins results in pulmonary

arteriovenous fistula

The condition in which the lung collapses, causing reduced lung volume, is described as

atelectasis

Pneumothorax radiographically appears as

an area without pulmonary markings

Thickened infected liquid or pus in the pleural space describes

empyema

The mediastinum contains

heart, trachea, esophagus, and thymus gland

To best demonstrate the mediastinum, the chest image must be completed with

no rotation, true PA positioning

Paradoxical movement of the diaphragm best demonstrated on fluoro dscribes

paralysis of the diaphragm
