CCTC NUR 120 RESPIRATORY DISORDERS Exam Questions
with 100% Correct Answers Latest Graded A+
Question:
Ventilation-
Answer:
movement of air in and out of the airways
Question:
Function of upper respiratory tract:
Answer:
warms and filters inspired air so that the lower respiratory tract (the lungs) can accomplish gas
exchange or diffusion
Question:
Upper respiratory tract consists of:
Answer:
nose, paranasal sinuses, pharynx, tonsils, adenoids, larynx, and trachea
Question:
Where does gas exchange occur?
Answer:
alveoli
Question:
Apnea-
Answer:
temporary cessation of breathing
Question:
Compliance-
Answer:
,measure of the force required to expand or inflate the lungs
Question:
Dyspnea-
Answer:
difficulty breathing
Question:
Hypoxemia-
Answer:
decrease in arterial oxygen tension in the blood
Question:
Hypoxia-
Answer:
decrease in oxygen supply to the tissues and cells
Question:
Pulmonary diffusion-
Answer:
exchange of gas molecules (oxygen and carbon dioxide) from areas of high concentration to areas
of low concentration
Question:
pulmonary perfusion-
Answer:
blood flow through the pulmonary vasculature
Question:
respiration-
Answer:
gas exchange between atmospheric air and the blood and between the blood and cells of the body
,Question:
lateral portion of the body verses the front portion of the body
Answer:
lateral should be smaller than the front
Question:
Cells in the Alveoli: Type 1-
Answer:
95% of alveoli have type 1 cells. They provide a barrier between the air the pt is breathing and the
alveolar surface
Question:
Cells in the alveoli: Type 2-
Answer:
produces surfactant and type 1 cells
Question:
Cells in the alveoli: Type 3-
Answer:
alveolar macrophage, they are phagocytic cells that ingest foreign matter and as a result provide an
important defense mechanism
Question:
Type 1 and Type 2 cells in the alveoli make up the:
Answer:
alveolar epithelium
Question:
Surfactant-
Answer:
reduces surface tension and improves overall lung function
Question:
, How many alveoli is the lung made up of?
Answer:
about 300 million
Question:
visceral pleura:
Answer:
covers the lungs
Question:
Parietal pleura:
Answer:
lines the thoracic cavity, lateral wall of the mediastinum, diaphragm, and inner aspects of the ribs
Question:
Mediastinum:
Answer:
in the middle of the thorax, between the pleural sacs that contain the two lungs. It contains all the
thoracic tissue outside the lungs
Question:
Things that affect the volume in someones lungs:
Answer:
age, health condition, capacity
Question:
Oxygen Transport:
Answer:
Oxygen is supplied to, and carbon dioxide is removed from, cells by way of the circulating blood
through the thin walls of the capillaries. Oxygen diffuses from the capillary through the capillary
wall to the interstitial fluid. At this point, it diffuses through the membrane of tissue cells, where it
is used by mitochondria for cellular respiration.
