Correct Answers | Verified | Latest Update 2026
What conducts air to the lower airways, protects the lungs from foreign matters,
warms, filters, and humidifies air. - CORRECT ANSWER -Upper respiratory tract
Participated in gas exchange, but oxygenating blood and excreting carbon dioxide
at the alveoli - CORRECT ANSWER -Lower respiratory tract
This type of respiratory failure occurs 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 - CORRECT ANSWER -Hypoxemic respiratory failure
This type of respiratory failure occurs when carbon dioxide in arterial blood is
greater than 50MmHg
• a common cause would be COPD and asthma. - CORRECT ANSWER -
Hypercapnic respiratory failure
What is true about all restrictive lung disorders? - CORRECT ANSWER -They
impair lung ventilation, and they impair lung inflation
, This is an infectious process that impairs gas exchange. - CORRECT ANSWER -
Pneumonia
In what infectious process are the alveoli filled with purulent material which
prevents the exchange of oxygen and carbon dioxide? - CORRECT ANSWER -
Pneumonia
This kind of pneumonia is caused by anaerobic bacteria, swallowed by the
oropharynx - CORRECT ANSWER -Aspiration pneumonia
What disorder is a pulmonary embolism, most commonly a complication of -
CORRECT ANSWER -Deep vein thrombosis
What is often caused by diseases that and pear, gas exchange or oxygenation? -
CORRECT ANSWER -Shortness of breath also known as dyspnea
A low blood oxygen level can trigger what - CORRECT ANSWER -Dyspnea
What is triggered by mechanical or chemical irritants to the airways including
excess mucus caused by inflammation - CORRECT ANSWER -Coughing
This disease affects the lower airways specifically the alveoli the crackles and
Ronke are suggestive of lower airway. Inflammation is fluid and pus from the
inflammatory process created sounds - CORRECT ANSWER -Pneumonia
