NSG300 Exam 3 2025, NSG 300 nursing exam, nursing
questions and answers, clinical nursing exam, intermediate
nursing concepts, NSG300 test prep
3 steps in the process of oxygenation: - ans -ventilation, perfusion, and diffusion
Is inspiration an active or passive process? - ans -active; stimulated by chemical
receptors in the aorta
Is expiration an active or passive process? - ans -passive; depends on the elastic
recoil properties of the lungs, requiring little or no muscle work
TRUE or FALSE: clubbing will not occur in patients with asthma. - ans -FALSE
What is lung capacity based off of? - ans -Age
Gender
Height
Where does pulmonary circulation begin? - ans -pulmonary artery
which receives poorly oxygenated blood from the right ventricle
What affects the rate of gas diffusion in the lungs? - ans -the thickness of the
alveolar capillary membrane
What issues cause a thicker alveolar membrane? - ans --pulmonary edema
-pulmonary infiltrates
-pulmonary effusion
What chronic diseases alter the amount of alveolar capillary membrane surface? -
ans --emphysema
-pneumothorax
-lobectomy
TRUE or FALSE: you can never give too much O2 to a patient with COPD - ans -
FALSE
, if you do so then they will not be able to properly expel CO2
What three things influence the capacity of the blood to carry O2? - ans -1. the
amount of dissolved O2 in the plasma
2. the amount of hemoglobin
3. the ability of the hemoglobin to bind with O2
What does the CNS regulate in terms of respiration? - ans -rate, depth, and
rhythm
What does the cerebral cortex regulate in terms of respiration? - ans -voluntary
control of respiration
What does chemical regulation do in terms of respirations? - ans -maintains
appropriate rate and depth based on changes in CO2, O2, and hydrogen ion
concentrations in the blood (pH).
Where are chemoreceptors found in the body? - ans -aortic and carotid bodies
TRUE or FALSE: oxygen decreases as a secondary effect with anemia. - ans -TRUE
What would increase in someone with chronic hypoxemia? - ans -RBCs
(polycythemia)
this is the adaptive response of the body to increase the amount of hemoglobin.
What nervous system diseases may affect breathing? - ans -myasthenia gravis,
polio, & guillain-barre
TRUE or FALSE: sickle cell anemia patients could have low SpO2. - ans -TRUE
What are some conditions that may affect chest wall mvement? - ans -pregnancy
obesity
neuromuscular disease
musculoskeletal abnormalities
trauma
