#1
Which gas is primarily responsible for the process of oxygenation in the human body?
Oxygen
ExplanationOxygen is essential for the oxygenation of tissues and organs in the body.
#2
What is the medical term for difficulty in breathing?
Dyspnea
ExplanationDyspnea refers to the sensation of difficulty or discomfort in breathing.
#3
What is the primary function of the respiratory system?
Facilitate gas exchange
ExplanationThe primary function of the respiratory system is to facilitate the exchange of oxygen and carbon dioxide between the body and the environment.
#4
What is the term for the tiny air sacs in the lungs where gas exchange occurs?
Alveoli
ExplanationAlveoli are the small air sacs in the lungs where oxygen and carbon dioxide exchange occurs.
#5
What is the term for the process of breathing out air from the lungs?
Expiration
ExplanationExpiration is the process of exhaling air from the lungs.
#6
Which of the following conditions is characterized by low levels of oxygen in the blood?
Hypoxemia
ExplanationHypoxemia indicates an inadequate amount of oxygen in the bloodstream.
#7
Which respiratory condition is characterized by the inflammation of the bronchial tubes?
Bronchitis
ExplanationBronchitis involves inflammation of the bronchial tubes, leading to coughing and mucus production.
#8
Which respiratory disorder is characterized by the collapse of lung tissue?
Atelectasis
ExplanationAtelectasis involves the collapse of lung tissue, impairing oxygen exchange.
#9
What is the term for the involuntary cessation of breathing during sleep?
Apnea
ExplanationApnea refers to a temporary pause in breathing during sleep.
#10
Which of the following is a treatment option for severe hypoxemia?
Oxygen therapy
ExplanationOxygen therapy is administered to increase oxygen levels in the blood of patients with severe hypoxemia.
#11
Which of the following is NOT a potential complication of prolonged hypoxia?
Hypothermia
ExplanationHypothermia is not directly related to prolonged hypoxia but to low body temperature.
#12
Which of the following is a common symptom of acute respiratory distress syndrome (ARDS)?
Cyanosis
ExplanationCyanosis, characterized by a bluish discoloration of the skin, is a common symptom of ARDS due to oxygen deprivation.
#13
What is the primary function of surfactant in the lungs?
Prevent alveolar collapse
ExplanationSurfactant reduces surface tension in the alveoli, preventing them from collapsing during exhalation.
#14
Which of the following is a common cause of acute respiratory distress syndrome (ARDS)?
Pulmonary embolism
ExplanationPulmonary embolism, a blockage in the pulmonary artery, can lead to ARDS by reducing blood flow to the lungs.
