UTA Nurs 5315 Mod 6 Dr. Gonzalez
Exam 2026 Questions and Answers
Minute Ventilation is a ___________ - Correct answer-Measure of how effective
ventilation is
RR x volume of air per breath
Alveolar ventilation an only be assessed by measuring a __________ - Correct
answer-PaCO2
The ________ and the _____________ are located in the medulla and are
responsible for controlling breathing patterns - Correct answer-Dorsal respiratory
group (DRG)
Ventral respiratory group (VRG)
Where are the peripheral chemoreceptors located that monitor ? - Correct answer-
aorta and carotid arteries
pH and PaO2 levels

,What is compliance used to describe? - Correct answer-how easily the lungs and
chest wall can be stretched
________ compliance means that the lungs and chest wall are difficult to inflate -
Correct answer-decreased
Compliance ______ with COPD - Correct answer-increases
What are 4 things in which you would see decreased compliance? - Correct
answer-- acute respiratory distress syndrome
- pneumonia
- pulmonary edema
- pulmonary fibrosis
In normal physiology, the airway resistance is normally very ____ - Correct
answer-Low
bronchoconstriction naturally ____________________ - Correct answer-increases
airway resistance
caused by smooth muscles of PNS
_____ distribution of ventilation and perfusion is required for effective gas
exchange - Correct answer-Equal

, The bases of the lungs are better perfused when in the _________________. -
Correct answer-upright position
Ventilation is greater than perfusion in the _____ - Correct answer-apices (very
top)
Perfusion is greater than ventilation in the _____ - Correct answer-bases of the
lungs
What is the ventilation perfusion ratio? - Correct answer-the relationship between
ventilation and perfusion
-normal ratio is 0.8=amount by which perfusion exceeds ventilation
What is V/Q mismatch? - Correct answer-Ideally, ventilation is matched to
perfusion in order for adequate gas exchange. (normally with exercise V/Q
approaches 1)
- imbalance in ventilation and perfusion of the alveoli
Apex of lung, V/Q = 3 (wasted ventilation)
Base of lung, V/Q = 0.6 (wasted perfusion)
