Chapter 3: Respiratory System - Test Bank

External respiration takes place within the:

• Bronchi

• Bronchioles

• Alveoli

• Trachea

The lower respiratory system consists of:

• Oropharynx, bronchi, and bronchioles

• Trachea, nasopharynx, and alveoli

• Trachea, bronchi, and bronchioles

• Larynx, trachea, and bronchi

The thin-walled sac where oxygen and carbon dioxide are exchanged with the blood in the pulmonary circulatory system is a(n):

• Bronchiole

• Alveolus

• Tertiary bronchus

• Alveolar duct

The trachea is:

• A noncollapsible tubular structure of C-shaped cartilage

• A boxlike structure consisting of nine pieces of cartilage

• Connected to the nasopharynx superiorly

• A noncollapsible tubular structure of oval-shaped cartilage

The blood supply to nourish and support lung tissue is the:

• Low-pressure system

• Pulmonary circulation

• Bronchial circulation

The serous membrane lining that adheres to the chest wall is the:

• Parietal viscera

• Visceral pleura

• Parietal pleura

• Serous fibrous pleura

For what purpose is a chest radiograph obtained after endotracheal tube insertion?

• To check for pneumonia

• To insure proper placement/position

• To check for puncture of the trachea

• All of these are reasons to obtain a chest radiograph after endotracheal tube insertion.

What result can occur when an endotracheal tube is positioned too high?

• pneumothorax

• pneumomediastinum

• left lung atelectasis

• aspiration pneumonia

What is a common result of an endotracheal tube that is positioned too low and into the right main stem bronchus?

• pneumothorax

• pneumomediastinum

• left lung atelectasis

• right main stem bronchus puncture

What image is obtained to verify the correct placement of a central venous catheter?

• Chest radiograph

• KUB

• Soft tissue neck
