NSG-530 Quiz 2 Questions and Answers
Question 1.
alveoli epithelial cells
Correct Answer: Type I alveolar cells (alveolar structure) Type II alveolar cells
(surfactant production)
Question 2.
1.Which of the following is TRUE regarding the pulmonary system? A.Each lobe is divided
into bronchi. B.The left lobe is divided into three lobes. C.The mediastinum contains the
lungs and heart. D.The larynx connects the upper and lower airways.
Correct Answer: Correct Answer: D The larynx connects the upper and lower
airways. The mediastinum is located between the lungs and contains the heart,
great vessels, andesophagus. The right lung has three lobes, and the left lung
has two. Each lobe is divided into segments and lobules
Question 3.
Neurochemical control: Respiratory center
Correct Answer: •Dorsal and ventral respiratory groups •Pneumotaxic and
apneustic centers
Question 4.
Neurochemical control: Lung receptors
Correct Answer: •Irritant receptors •Stretch receptors
Question 5.
Neurochemical control: Chemoreceptors:
Correct Answer: Central chemoreceptors Peripheral chemoreceptors
Question 6.
Muscles of Breathing: Major muscles of inspiration
Correct Answer: Diaphragm External intercostals
Question 7.
Muscles of Breathing: Accessory muscles of inspiration
Correct Answer: ØSternocleidomastoid muscle ØScalene muscles
Question 8.
Mechanics of Breathing: Gas Transport
Correct Answer: Four steps ØVentilation of the lungs ØDiffusion of oxygen from
, the alveoli into the capillary blood ØPerfusion of systemic capillaries with
oxygenated blood ØDiffusion of oxygen from systemic capillaries into the cells
Diffusion of CO2 occurs in reverse order
Question 9.
1.A patient has bulbous enlargement of the distal segments of the fingers. Which disease
is associated with this condition? A.Cystic fibrosis B.Acute pneumonia C.Sickle cell disease
D.Acute myocardial infarction
Correct Answer: A This condition describes clubbing, in which there is
enlargement of the distal segment of the finger. It is associated with conditions
of decreased oxygenation such as bronchiectasis, cystic fibrosis, pulmonary
fibrosis, lung abscess, and congenital heart disease.
Question 10.
Open pneumothorax
Correct Answer: An open wound to the chest that allows air to enter the pleural
space and cause lung collapse
Question 11.
tension pneumothorax
Correct Answer: a pneumothorax with rapid accumulation of air in the pleural
space causing severely high intrapleural pressures with resultant tension on the
heart and great vessels.
Question 12.
Spontaneous (primary) pneumothorax
Correct Answer: Occurs in the absence of a traumatic injury to the chest or a
known lung disease
Question 13.
secondary pneumothorax
Correct Answer: Underlying lung disease leads to weakened small airways which
collapse with respirations.
Question 14.
Pleural effusion
Correct Answer: fluid in pleural space ØTransudative (watery) ØExudative
(WBCs and plasma proteins) ØHemothorax (blood) ØEmpyema (pus) Chylothorax
(chyle)
Question 15.
Acute respiratory distress syndrome (ARDS)
Question 1.
alveoli epithelial cells
Correct Answer: Type I alveolar cells (alveolar structure) Type II alveolar cells
(surfactant production)
