WGU D236 Pathophysiology –
Respiratory System Exam
What conducts air to the lower airways, Upper respiratory tract
protects the lungs from foreign matters,
warms, filters, and humidifies air.
Participated in gas exchange, but Lower respiratory tract
oxygenating blood and excreting
carbon dioxide at the alveoli
This type of respiratory failure occurs Hypoxemic respiratory failure
when the pressure of oxygen in arterial
blood is lower than 60 mmHg with
normal arterial carbon dioxide.
Ex include;
• pulmonary edema
• PE
• pneumonia
• Pneumothorax
This type of respiratory failure occurs when Hypercapnic respiratory failure
carbon dioxide in arterial blood is greater
than 50MmHg
• a common cause would be
COPD and asthma.
What is true about all restrictive lung They impair lung ventilation, and they impair lung inflation
disorders?
This is an infectious process that impairs gas Pneumonia
exchange.
In what infectious process are the alveoli Pneumonia
filled with purulent material which
prevents the exchange of oxygen and
carbon dioxide?
This kind of pneumonia is caused by Aspiration pneumonia
anaerobic bacteria, swallowed by the
oropharynx
What disorder is a pulmonary embolism, Deep vein thrombosis
most commonly a complication of
What is often caused by diseases that and Shortness of breath also known as dyspnea
pear, gas exchange or oxygenation?
A low blood oxygen level can trigger what Dyspnea
, What is triggered by mechanical or chemical Coughing
irritants to the airways including excess
mucus caused by inflammation
This disease affects the lower airways Pneumonia
specifically the alveoli the crackles
and Ronke are suggestive of lower
airway.
Inflammation is fluid and pus from the
inflammatory process created sounds
What is most commonly caused by bacteria, Pneumonia
but can also be caused by viruses or fungi?
• common cold Upper respiratory tract
• epiglottitis
• Laryngitis
• pharyngitis (sore throat)
• sinusitis(sinus infection)
• mono
• Rhinitis
The above are all infections that affect what
part of the respiratory tract
• bronchitis The lower respiratory tract
• pneumonia
• Bronchiolitis
• Tuberculosis
The above infections affect what part of the
respiratory tract
This is a long term lung disease caused by Call workers pneumoconiosis
inhaling large amount of crystalline silica
dust.
• the lungs are damaged: silicosis
What causes bronchial obstruction due to Asthma
hypersensitive or hyperresponsive
airways
This is triggered by a type one Extrinsic asthma
hypersensitivity reactions
This has an adult onset due Intrinsic asthma
to hyperresponsive airway
tissue
• cold Asthma attack
• exercise
• Stress
• Inhalant of irritant
These are all triggers, or risk factors of what
