ALU 201 Chapter 7: Respiratory System Exam Prep 2026 |
Questions & Answers
1. What condition is often associated with sleep apnea?
Bronchitis
Pneumonia
Obesity
Asthma
2. Describe the significance of measuring Maximum Voluntary Ventilation (MVV)
in pulmonary function tests.
MVV measures the maximum amount of air a person can breathe in
and out in one minute, indicating respiratory muscle strength and
overall lung function.
MVV determines the rate of airflow during forced expiration.
MVV evaluates the efficiency of gas exchange in the alveoli during
respiration.
MVV assesses the volume of air remaining in the lungs after exhalation,
reflecting lung capacity.
3. What is the name of the structures in the lungs where gas exchange takes
place?
Larynx
Bronchi
Trachea
Alveoli
,4. The most common way of obtaining visual assessment of the
tracheobronchial tree and acquire a sample is using a:
chest x-ray
magnetic resonance imaging (MRI)
fiberoptic bronchoscopy
endoscopy
5. What is the relationship between the progression of chronic lung diseases
and the severity of symptoms?
Progression is always rapid regardless of symptoms.
Symptoms are only present during acute episodes.
There is no correlation between progression and symptoms.
If progression has been slow, it may continue to be so, and
symptoms are persistent.
6. Which of the following components of a polysomnogram (PSG) is used to
monitor eye movements?
EMG
EEG
ECG
EOG
7. What are symptoms associated with OSA?
Frequent waking
Snoring
, Sleep fragmentation
All the above
8. What type of blood is received by the right ventricle of the heart?
Nutrient-rich blood
Oxygenated blood
Deoxygenated blood
Carbon dioxide-rich blood
9. Why is assessing functional residual capacity (FRC) more relevant than total
lung capacity (TLC) in diagnosing conditions like hyperinflation?
FRC is easier to measure than TLC, making it a preferred choice.
TLC measures the total lung volume, which is more relevant for
assessing lung diseases.
FRC provides a better indication of the air trapped in the lungs after
normal breathing, which is crucial for diagnosing hyperinflation.
TLC reflects the efficiency of gas exchange in the lungs.
10. What is the term used to describe the bulbous enlargement of the tips of the
fingers and toes associated with certain health conditions?
Clubbing
Cyanosis
Edema
Pallor
11. What is the number of lobes in the right lung?
, 3
2
4
5
12. In a patient experiencing central apneas while using CPAP, what would be
the most appropriate next step in their treatment plan?
Add supplemental oxygen
Increase the CPAP pressure
Switch to BiPAP therapy
Continue with CPAP without changes
13. Describe the significance of airflow cessation in diagnosing sleep apnea.
Airflow cessation is irrelevant to sleep apnea diagnosis.
Airflow cessation is a common symptom of insomnia, not sleep
apnea.
Airflow cessation only occurs in severe cases of sleep apnea.
Airflow cessation during sleep is a key indicator of sleep apnea, as
it disrupts normal breathing patterns.
14. Which of the following is the gold standard for detecting pulmonary emboli
CT scan
ventilation and perfusion scans
MRI
pulmonary arteriography
