Gas Exchange: Physiology, Impairments, and Nursing Care
Exam Newest 2026 Questions and Correct Detailed Answers
Already Graded A+
What is gas exchange? - CORRECT ANSWER-The process by which oxygen is
transported to cells and carbon dioxide is transported from cells.
Which systems interact during gas exchange? - CORRECT ANSWER-The
neurologic, respiratory, and cardiovascular systems.
What is the role of hemoglobin in gas exchange? - CORRECT ANSWER-
Hemoglobin carries oxygen from the lungs to cells and transports carbon dioxide
from cells to the lungs.
What happens when gas exchange is impaired? - CORRECT ANSWER-It can
lead to insufficient oxygen (hypoxia) and cessation of gas exchange can result in
anoxia.
What happens to infants born before 36 weeks of gestation regarding gas
exchange? - CORRECT ANSWER-They may lack sufficient surfactant, leading to
collapsed alveoli.
, What respiratory changes occur in older adults? - CORRECT ANSWER-
Diminished strength of respiratory muscles and reduced elasticity of alveoli,
leading to dyspnea.
What are some disorders that affect gas exchange? - CORRECT ANSWER-
Asthma, pneumonia, and chronic obstructive pulmonary disease (COPD).
What are the three broad categories representing problems associated with gas
exchange? - CORRECT ANSWER-Ventilation, transport, and perfusion.
How does aging affect erythrocyte levels? - CORRECT ANSWER-Older adults
experience a reduction in erythrocytes, increasing their risk of anemia.
What is the role of the diaphragm in gas exchange? - CORRECT ANSWER-It
contracts to create negative pressure that pulls in atmospheric air.
How does the nervous system regulate breathing? - CORRECT ANSWER-
Breathing is involuntary and regulated automatically by the nervous system to
maintain arterial blood gas levels.
