NUR 500 Module 2, Week 3 Pulmonology Questions With
Complete Solutions
Module Outcomes: 1. Identify the basic structure and function of
cells within the pulmonary system required for gas exchange. 2.
Identify main causes, and clinical manifestations of diseases,
conditions, and disorders of the pulmonary system. 3. Identify
age-related differences in structure and function of the
pulmonary system.
ARDS (acute respiratory distress syndrome) Correct Answer
Thickening of the walls and the fluid inside the alveoli that
prevents gas exchange
Can be fatal. If someone recovers, they are living with a lot of
scarring/damage
Bronchiolitis (pulmonary alterations in children) Correct
Answer Viral induced respiartory infection causing
inflammation and necrosis of bronchial epithelium
Most commonly caused by RSV (Respiratory Syncytial Virus)
S/S: rhinorrhea, tight/dry cough, decreased appetite, lethargy,
and fever
Describe what is happening during a physiological dead space
(V/Q mismatch) Correct Answer Here the alveolus is okay
but the actual arterial vessel is not working (no blood flow
whatsoever)
, Describe what is happening during a shunt (V/Q mismatch)
Correct Answer A poorly ventilated alveolus (might be caused
by COPD) causes poorly oxygenated blood flow which leads to
decreased oxygenation (shunt)
How does aging effect the pulmonary system? Correct Answer
- loss of elastic recall
- stiffening of chest wall
-alterations of gas exchange
- increases in flow resistance
- alveoli tend to lose alveoli wall tissues and capillaries
- decreased in PaO2 and diminished ventilatory reserve causing
a decrease in exercise tolerance
- decrease in respiratory muscle strength and endurance
How does the body achieve the exchange of oxygen and carbon
dioxide between the environment and the blood? Correct
Answer The pulmonary system utilizes ventilation or the
movement between the environment and the lungs via inhalation
and exhalation.
Oxygen dissociation curve Correct Answer A curve on a
graph that shows how saturated with oxygen haemoglobin is at
any given partial pressure.
Pulmonary alterations in children (Croup) Correct Answer
croup (subglottic edema from infection)
s/s: rhinorrhea, sore throat, low grade fever followed by harsh
seal like barking coughs
