NURS 621 Respiratory Disorders 1 questions with
correct answers
1. Describe ventilation, diffusion, and perfusion. Correct Answer-
Ventilation is the movement of air into and out of lungs, Diffusion is the
movement of gases between air spaces in the lungs and the blood stream,
perfusion is the movement of blood into and out of the capillary beds of
lungs to body organs and tissue.
2. _____ airways provide a passage for the movement of air into and out
of the gas-exchanged structures of the lung. Correct Answer-Conducting
airways such as nasal passages, mouth, pharynx, trachea, bronchi, etc.
3. The bronchial walls have 3 layers of tissue lining, epithelial, smooth
muscle, connective. Which one has goblet cells? Correct Answer-
Epithelial layer has mucus secreting goblet cells.
4. Which Alveolar cells are involved with gas exchange and structure?
Correct Answer-Type 1 alveolar cells that are flat squamous single layer.
5. What are some functions of type 2 alveolar cells? Correct Answer-
Produce surfactant that coats inner surface of alveolus to help expansion
during inspiration and lower surface tension at end-expiration preventing
atelectasis. Inflammatory response, primary defense.
6. Does inhalation or exhaling require energy? Correct Answer-
Inhalation is an active process requiring contracting of muscles.
Exhaling is passive.
, 7. When inhaling, what does the diaphragm do? Correct Answer-
Contract and flatten, creating negative pressure in lungs.
8. Air moves from an area of high/Positive pressure to an area of?
Correct Answer-Low/negative pressure.
9. Amount of air that moves into and out of the lungs during a normal
breath. Correct Answer-Tidal Volume
10. Maximum amount of air that can be moved into and out of the lung.
Correct Answer-Vital Capacity.
11. Volume of air remaining in the lung after expiration. Always air left.
Correct Answer-Residual Volume
12. passageways or areas where gas exchange cannot occur. Correct
Answer-Dead Space.
13. The stretch. The ability of the lungs to expand. Correct Answer-
Compliance.
14. The tendency of lungs to return to the resting state after inspiration.
Correct Answer-Elastic recoil.
