2026 Update) Foundations of Nursing
Exam | Questions with Verified Answers |
100% Correct | Grade A – GCU.
What is lung capacity based off of? Age
Gender
Height
Where does pulmonary circulation begin? pulmonary artery
which receives poorly oxygenated blood from the right ventricle
What affects the rate of gas diffusion in the lungs? the
thickness of the alveolar capillary membrane
What issues cause a thicker alveolar membrane? -pulmonary
edema
-pulmonary infiltrates
-pulmonary effusion
,What chronic diseases alter the amount of alveolar capillary
membrane surface? -emphysema
-pneumothorax
-lobectomy
TRUE or FALSE: you can never give too much O2 to a patient with
COPD 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?
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? rate,
depth, and rhythm
What does the cerebral cortex regulate in terms of respiration?
voluntary control of respiration
, What does chemical regulation do in terms of respirations?
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? aortic and
carotid bodies
TRUE or FALSE: oxygen decreases as a secondary effect with
anemia. TRUE
What would increase in someone with chronic hypoxemia?
RBCs (polycythemia)
this is the adaptive response of the body to increase the amount
of hemoglobin.
What nervous system diseases may affect breathing?
myasthenia gravis, polio, & guillain-barre
TRUE or FALSE: sickle cell anemia patients could have low SpO2.
TRUE
