NUR 323 Exam #2 UPDATED ACTUAL Questions and
CORRECT Answers
oxygenation the process of supplying O₂ to all cells of the body by way of the
cardiopulmonary system
airway system passageways for air to move in and out of lungs
alveolar system basic unit in lungs in contact with pulmonary capillaries
cardiovascular system heart and vessels (pump, hoses)
gas exchange Diffusion of gases from higher to lower pressure (high to low concentration).
Interactive process involving the neurologic, pulmonary, cardiovascular
systems
gas exchange is made possible through... 1. Ventilation (breathing) - neurologic
2. Respiration (gas exchange) - pulmonary
3. Perfusion - cardiovascular systems
changes in gas exchange result with conditions that temporary
are... long term
permanent
acute conditions that lead to gas exchange impairment asthma flare-up, pneumonia
chronic conditions that lead to gas exchange emphysema, chronic bronchitis, COPD
impairment
conditions involving a gas exchange impairment Neurologic: condition affecting brain and spinal cord
Cardiovascular: condition affection blood flow in heart, arteries, veins
Hematologic: anemia
, health situations interrelated/closely linked to gas acid base balance
exchange perfusion
mobility
fatigue
nutrition
anxiety
perfusion The transport of oxygenated blood through arteries to capillaries to cells
delivering oxygen and nutrients
perfusion requires... 1. the heart to pump enough blood to tissues
2. arteries and capillaries to be patent (open)
types of perfusion central
tissus
central perfusion relies on an intact blood delivery mechanism
heart functions & blood vessels
tissue perfusion relies on the amount of blood available to target tissues
Ineffective movement/blockages of blood flow in vessels (arteries, veins,
capillaries)
changes in perfusion result with conditions that are temporary
long term
permanent
conditions leading to perfusion impairment acute and chronic
conditions involving perfusion impairment Neurologic: interfering with blood flow within the brain
Pulmonary: impairing blood flow to and from the lungs
Cardiovascular: interfering with blood flow in heart, arteries and veins
health situations interrelated/closely linked to perfusion pain
cognition
elimination
gas exchange
mobility
nutrition
patient education
inflammation
intracranial regualtion
stress and coping
oxygenation AND perfusion cargo blood
nutrients
oxygen
factors effecting the respiratory and cardiovascular Level of Health (acute illness, chronic disease)
systems Physical Changes of Aging
Medications (CNS effects, heart rate)
Lifestyle
Environmental (air quality)
Psychological Health (stress, anxiety)
