AACN Critical Care Nursing exam
2024 with 100% correct answers
Cellular respiration cannot be directly measured but is estimated by the amount
of - correct answer CO2 produced ( CO2) V̇ and the amount of O2 consumed
(V̇O2).
V̇CO2 - correct answer CO2 produced in celluar respiration
V̇O2 - correct answer and the amount of O2 consumed in cellular respiration
external respiration - correct answer The Exchange of O2 and CO2 at the alveolar-
capillary level.
It is the ratio of the CO2 produced to the O2 taken up per minute.
V̇CO2/min : V̇O2/min
Proper functioning of the respiratory circuit requires efficient interaction of the -
correct answer 1.
respiratory
2.circulatory
3.neuromuscular systems.
In addition to its primary function of O2 and CO2 exchange, the lung also carries out
metabolic and endocrine functions as a source of hormones and a site of hormone
metabolism.
In addition, the lung is a target of hormonal actions by other endocrine organs -
correct answer (e.g., surfactant production and potentially activation of
bradykinin).

, Anatomic divisions of Lungs:
Right lung:
Left Lung: - correct answer Right Lung: 3 lobes—upper, middle, lower
Left lung (two lobes—upper, lower).
Lobes are divided into bronchopulmonary segments - correct
answer 10 - RIGHT 9 - LEFT
Bronchopulmonary segments are subdivided into - correct answer secondary
lobules
Secondary Lobules - correct answer Independent respiratory
units of lung each bronchopulmonary segment is supplied
independently by:
a (tertiary) segmental bronchus a tertiary branch of pulmonary
artery - carry low oxygen ("venous") blood to lungs for oxygenation
a branch of bronchial artery
What does a a tertiary branch of pulmonary artery do for secondary lobules? -
correct answer - carries low oxygen ("venous") blood to lungs for oxygenation
Smallest gross anatomic units of lung tissue; contain the primary functional units of
the lung - correct answer Lobule:
Lobule (the smallest gross anatomic units of lung tissue) consists of - correct
answer 1. terminal bronchioles
2.alveolar ducts and sacs
3.pulmonary circulation
