Role Of Oxygen In Respiration! Trivia Facts Quiz

2.

What are the two critical elements of gas exchange?

Oxygen and Carbon Dioxide
Oxygen and Carbon Monoxide
Nitrogen and Oxygen
Nitrogen and Carbon Monoxide

Correct Answer

A. Oxygen and Carbon Dioxide

Explanation

The two critical elements of gas exchange are oxygen and carbon dioxide. During gas exchange, oxygen is taken in by the body and carbon dioxide is expelled. Oxygen is necessary for cellular respiration, where it is used to produce energy. Carbon dioxide is a waste product of cellular respiration and needs to be removed from the body. Therefore, the correct answer is oxygen and carbon dioxide.

Respiratory failure associated with an oxygen demand exceeding oxygen delivery is known as _____________.

Hypoxemic
Hypercapnic
Hyperoxemia
Hypocapnic

Correct Answer

A. Hypoxemic

Explanation

Respiratory failure associated with an oxygen demand exceeding oxygen delivery is known as hypoxemic. This means that there is a deficiency of oxygen in the blood, leading to inadequate oxygenation of the body's tissues. Hypercapnic refers to respiratory failure caused by an excess of carbon dioxide in the blood. Hyperoxemia refers to an excessive amount of oxygen in the blood. Hypocapnic refers to respiratory failure caused by a deficiency of carbon dioxide in the blood.

Asthma and COPD are both common causes of hypoxemia and hypercapnia.

True
False

Correct Answer

A. True

Explanation

Asthma and COPD are both respiratory conditions that can lead to hypoxemia (low oxygen levels in the blood) and hypercapnia (high carbon dioxide levels in the blood). In asthma, the airways become inflamed and narrow, making it difficult to breathe. This can result in decreased oxygen levels and increased carbon dioxide levels in the blood. Similarly, in COPD (chronic obstructive pulmonary disease), the airways become obstructed, causing difficulty in breathing and impaired gas exchange. Therefore, it is true that both asthma and COPD can be common causes of hypoxemia and hypercapnia.

5.

Respiratory failure is always associated with respiratory disease.

True
False

Correct Answer

A. False

Explanation

Respiratory failure is not always associated with respiratory disease. It can also occur due to other factors such as trauma, drug overdose, or neurological conditions. Therefore, the statement that respiratory failure is always associated with respiratory disease is false.

Common modifiable risk factors associated with respiratory disease include all of the following except:

Tobacco use
Physical inactivity
Age
Occupational agents
Allergens

Correct Answer

A. Age

Explanation

Age is not a modifiable risk factor for respiratory disease because it is a natural and unavoidable process. While tobacco use, physical inactivity, occupational agents, and allergens can all be modified or controlled to reduce the risk of respiratory disease, age cannot be changed.

What is the name of a patient office visit in which the physician completes a full health interview, a physical exam, reviews imaging, PFTs and/or laboratory tests?

Evaluation and management (E&M)
Visit and Discharge (V & D)
Management and Assessment (M&A)
Interview and Discharge (I&D)

Correct Answer

A. Evaluation and management (E&M)

Explanation

The correct answer is Evaluation and management (E&M). This term refers to a patient office visit where the physician conducts a comprehensive health interview, performs a physical examination, and reviews any necessary imaging, pulmonary function tests (PFTs), and/or laboratory tests. It encompasses the overall assessment and management of the patient's health condition during the visit.

All of the following are commonly found with restrictive lung disease except:

Reduced lung compliance
Decrease VC
High to normal FEV1/FVC ratio
Low FEV1/FVC ratio

Correct Answer

A. Low FEV1/FVC ratio

Explanation

Restrictive lung disease is characterized by reduced lung compliance, which means the lungs are less able to expand and fill with air. This leads to a decrease in vital capacity (VC), the maximum amount of air that can be exhaled after a maximum inhalation. In restrictive lung disease, the FEV1/FVC ratio is typically high to normal, indicating that the forced expiratory volume in one second (FEV1) is relatively preserved compared to the forced vital capacity (FVC). Therefore, the correct answer is "Low FEV1/FVC ratio."

Asthma, bronchitis and emphysema are all classified as restrictive lung diseases.

True
False

Correct Answer

A. False

Explanation

Asthma, bronchitis, and emphysema are not classified as restrictive lung diseases. They are actually classified as obstructive lung diseases. Restrictive lung diseases are characterized by a decrease in lung volume and a restriction in the ability of the lungs to expand. Obstructive lung diseases, on the other hand, are characterized by an obstruction in the airways, making it difficult to exhale air. Asthma, bronchitis, and emphysema all involve inflammation and narrowing of the airways, leading to obstructive symptoms such as wheezing and shortness of breath. Therefore, the correct answer is False.

10.

Respiratory disease can only be classified as either restrictive or obstructive as there is never overlap seen in the clinical setting.

True
False

Correct Answer

A. False

Explanation

This statement is false. In the clinical setting, it is possible for respiratory diseases to have both restrictive and obstructive components. For example, conditions such as chronic obstructive pulmonary disease (COPD) can present with both obstructive airflow limitation and restrictive lung function due to lung tissue damage and fibrosis. Therefore, respiratory diseases can have overlapping features and cannot be solely classified as either restrictive or obstructive.
