ExplanationA group of lung diseases characterized by obstruction to airflow that interferes with normal breathing.
#11
What is the function of surfactant in the lungs?
Facilitates lung expansion and prevents collapse
ExplanationA substance produced by the lungs that reduces surface tension, allowing the lungs to expand easily during inhalation and preventing collapse during exhalation.
#12
Which condition is characterized by the enlargement of air sacs in the lungs, causing breathing difficulties?
Emphysema
ExplanationA lung condition where the air sacs in the lungs are damaged and enlarged, leading to difficulty in breathing.
#13

#16
Which of the following is a common symptom of sleep apnea?
Excessive daytime sleepiness
ExplanationA sleep disorder characterized by pauses in breathing during sleep, leading to poor sleep quality and daytime sleepiness.
#17
Which of the following statements about the diaphragm is correct?

#19
What is the medical term for the act of coughing up and spitting out saliva or mucus?
Expectoration

#20
Which of the following is a condition characterized by the collapse of a lung or a portion of it?
Atelectasis
ExplanationA condition where part or all of a lung collapses, resulting in reduced or absent gas exchange.
#21
Which term refers to the surgical removal of a lung?
Pneumonectomy
ExplanationSurgical removal of all or part of a lung, often performed to treat lung cancer or severe lung diseases.
#22
In the acronym ARDS, commonly associated with severe respiratory distress, what does the letter 'R' stand for?
Respiratory
ExplanationAcute Respiratory Distress Syndrome, a severe lung condition characterized by fluid buildup in the air sacs, leading to low oxygen levels in the blood.
#23
Which of the following conditions is characterized by the accumulation of fluid in the pleural cavity, leading to compression of the lungs?
Pleural effusion
ExplanationA condition where fluid accumulates in the space between the lungs and chest wall, exerting pressure on the lungs and impairing their function.
#24
In the context of respiratory health, what does the term 'auscultation' refer to?
Listening to breath sounds with a stethoscope
ExplanationA diagnostic technique involving listening to sounds within the body, typically using a stethoscope, to assess respiratory and cardiac health.
