UTA NURS 5315 MOD 6 PULM AND
SHOCK UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS
◉ Alveolar ventilation an only be assessed by measuring a
__________
Answer: PaCO2
◉ The ________ and the _____________ are located in the medulla and
are responsible for controlling breathing patterns
Answer: Dorsal respiratory group (DRG)
Ventral respiratory group (VRG)
◉ Where are the peripheral chemoreceptors located that monitor
?
Answer: aorta and carotid arteries
pH and PaO2 levels
◉ What is compliance used to describe?
Answer: how easily the lungs and chest wall can be stretched
◉ ________ compliance means that the lungs and chest wall are
difficult to inflate
,Answer: decreased
◉ Compliance ______ with COPD
Answer: increases
◉ What are 4 things in which you would see decreased
compliance?
Answer: - acute respiratory distress syndrome
- pneumonia
- pulmonary edema
- pulmonary fibrosis
◉ In normal physiology, the airway resistance is normally very
____
Answer: Low
◉ bronchoconstriction naturally ____________________
Answer: increases airway resistance
caused by smooth muscles of PNS
◉ _____ distribution of ventilation and perfusion is required for
effective gas exchange
Answer: Equal
, ◉ The bases of the lungs are better perfused when in the
_________________.
Answer: upright position
◉ Ventilation is greater than perfusion in the _____
Answer: apices (very top)
◉ Perfusion is greater than ventilation in the _____
Answer: bases of the lungs
◉ What is the ventilation perfusion ratio?
Answer: the relationship between ventilation and perfusion
-normal ratio is 0.8=amount by which perfusion exceeds
ventilation
◉ What is V/Q mismatch?
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)
