NSG 300 Exam 3 Solution Manual Fully Solved Latest Update 2025 Already Passed
3 steps in the process of oxygenation: - Answers ventilation, perfusion, and diffusion
Is inspiration an active or passive process? - Answers active; stimulated by chemical receptors in the
aorta
Is expiration an active or passive process? - Answers 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. - Answers FALSE
What is lung capacity based off of? - Answers Age
Gender
Height
Where does pulmonary circulation begin? - Answers pulmonary artery
which receives poorly oxygenated blood from the right ventricle
What affects the rate of gas diffusion in the lungs? - Answers the thickness of the alveolar capillary
membrane
What issues cause a thicker alveolar membrane? - Answers -pulmonary edema
-pulmonary infiltrates
-pulmonary effusion
What chronic diseases alter the amount of alveolar capillary membrane surface? - Answers -emphysema
-pneumothorax
-lobectomy
TRUE or FALSE: you can never give too much O2 to a patient with COPD - Answers 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? - Answers 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? - Answers rate, depth, and rhythm
What does the cerebral cortex regulate in terms of respiration? - Answers voluntary control of
respiration
What does chemical regulation do in terms of respirations? - Answers 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? - Answers aortic and carotid bodies
TRUE or FALSE: oxygen decreases as a secondary effect with anemia. - Answers TRUE
What would increase in someone with chronic hypoxemia? - Answers RBCs (polycythemia)
this is the adaptive response of the body to increase the amount of hemoglobin.
What nervous system diseases may affect breathing? - Answers myasthenia gravis, polio, & guillain-
barre
TRUE or FALSE: sickle cell anemia patients could have low SpO2. - Answers TRUE
What are some conditions that may affect chest wall mvement? - Answers pregnancy
obesity
neuromuscular disease
musculoskeletal abnormalities
trauma
CNS alterations
Normal PaCO2 (arterial carbon dioxide): - Answers 35-45 mm Hg
Normal PaO2 (arterial oxygen): - Answers 80-100 mm Hg
S/S of hypoventilation: - Answers - mental status changes
- dysrhythmias
- potential cardiac arrest
