COLLAPSE OF ALVEOLI PREVENTING AIR EXCHANGE
- A.
TACHYPNEA
- B.
PNEUMOTHORAX
- C.
ATELECTASIS
Correct Answer
C. ATELECTASISExplanation
Atelectasis refers to the collapse or closure of alveoli, which are tiny air sacs in the lungs responsible for gas exchange. This condition prevents the proper exchange of air, leading to impaired oxygenation and carbon dioxide removal. Tachypnea, on the other hand, is an increased respiratory rate, while pneumothorax is the presence of air in the pleural cavity, causing lung collapse. However, the collapse of alveoli preventing air exchange is specifically described by atelectasis, making it the correct answer.Rate this question:

Emphysema is a diease of the
- A.
Pleura
- B.
Bronchi
- C.
Alveoli
Correct Answer
C. AlveoliExplanation
Emphysema is a disease of the alveoli. The alveoli are tiny air sacs in the lungs where oxygen is taken in and carbon dioxide is released. In emphysema, these air sacs become damaged and lose their elasticity, leading to difficulty in breathing. This condition is often caused by long-term exposure to irritants such as cigarette smoke. As a result of the damage to the alveoli, the lungs are unable to efficiently exchange oxygen and carbon dioxide, leading to shortness of breath and other respiratory symptoms.Rate this question:

Chest drainage serves two purposes, choose the two
- A.
Removes blood,air,and fluid from the pleural space
- B.
Restores neg pressure
- C.
Restores positive pressure
Correct Answer(s)
A. Removes blood,air,and fluid from the pleural space
B. Restores neg pressureExplanation
Chest drainage serves two purposes: removing blood, air, and fluid from the pleural space, and restoring negative pressure. By removing these substances from the pleural space, chest drainage helps to prevent complications such as pneumothorax or hemothorax. Additionally, restoring negative pressure helps the lungs to expand and function properly. Restoring positive pressure, on the other hand, is not a purpose of chest drainage and would not be beneficial in this context.Rate this question:

Hypoxia worsens when affected persons lung is positioned
- A.
Up
- B.
Down
- C.
Higher than good lung
Correct Answer
B. DownExplanation
When a person's lung is positioned downwards, it can worsen hypoxia. This is because the lung will be compressed by the weight of the body, reducing its ability to expand and take in oxygen. This can lead to a decrease in oxygen levels in the blood, exacerbating the symptoms of hypoxia. Therefore, positioning the affected lung downwards can further impair the already compromised oxygenation in the body.Rate this question:

Pneumonia
- B.
Pulmonary embolisim
- C.
Asthma
Correct Answer
B. Pulmonary embolisimExplanation
The given condition presents with dyspnea (difficulty breathing) accompanied by abrupt, constant, nonradiating pain that worsens on inspiration. These symptoms are indicative of a pulmonary embolism, which occurs when a blood clot blocks one or more arteries in the lungs. Pneumonia, on the other hand, typically presents with symptoms such as cough, fever, and chest pain that worsens with deep breaths. Asthma is characterized by wheezing, shortness of breath, and chest tightness, but it does not typically cause constant, nonradiating pain. Therefore, the correct answer is pulmonary embolism.Rate this question:

Air exchange in the lungs is by the process of
- A.
Osmosis
- B.
Transport
- C.
Diffusion
Correct Answer
C. DiffusionExplanation
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the lungs, oxygen from the inhaled air moves from the alveoli (where it is highly concentrated) into the bloodstream (where it is lower in concentration), while carbon dioxide moves from the bloodstream into the alveoli to be exhaled. This movement of gases occurs due to the concentration gradient created between the alveoli and the bloodstream, allowing for the exchange of gases to occur efficiently. Therefore, diffusion is the correct process for air exchange in the lungs.Rate this question:
