EDGT- Respiratory Questions 100% CORRECT SOLUTIONS 2023//2024 The bony structures that form the posterior walls of the nasal passages and are responsible for warming and humidifying inspired air are called the________? A.) cilia B.) Conchea C.) larynx D.) vibrissae - ANSWER conchae. -Conchae form the posterior walls of the nasal passages. They are responsible for warming and humidifying inspired air. The site(s) in which gas exchange occurs is (are) the___________? A.) bronchioles. B.) vibrissae. C.) alveoli. D.) nasopharynx. - ANSWER alveoli. -The alveoli are the sites in which gas exchange occurs via diffusion. Which of the following statements about the right lung is correct? A.)The right lung has three lobes. B.)The right lung is longer than the left lung. C.)The right lung is responsible for 40% of gas exchange. D.)The right lung is smaller than the left lung. - ANSWER The right lung has three lobes. -The right lung is shorter, wider, and larger than the left lung. It has three lobes and is responsible for 55% of gas exchange. Mrs. Walker's V/Q ratio is low. Pulmonary circulation is sufficient, but ventilation is not. This is referred to as A.) dead-space ventilation. B.) silent unit. C.) V/Q ratio of 4:5. D.) shunting. - ANSWER shunting. -Shunting occurs when the V/Q ratio is low. Pulmonary circulation is adequate but ventilation is not. The rate and depth of respirations are controlled by the A.) pons. B.) brain stem. C.) medulla. D.) lungs. - ANSWER medulla. -The medulla controls how fast we breathe (rate) and how deeply we breathe. Marian is deeply afraid of being enclosed in small spaces. She is riding in an elevator when it becomes "stuck" between floors. Marian begins to breathe very rapidly and very deeply for quite a while. Marian is in danger of developing A.) respiratory acidosis. B.) cardiac arrest. C.) respiratory alkalosis. D.) medulla malfunction. - ANSWER respiratory alkalosis -Rapid, deep breathing causes the elimination of excessive amounts of carbon dioxide, leading to respiratory alkalosis. Upon inspection of a patient's hands you notice clubbing of the fingers. This may be an indication of A.) hyperinflation of the lungs. B.) skeletal deformities. C.) tripod position. D.) long-term hypoxia. - ANSWER long-term hypoxia -Clubbing may be a sign of long-term hypoxia. Which of the following statements about gas exchange is accurate? A.) The right and left pulmonary arteries carry oxygenated blood from the lungs to the left side of the heart. B.) Carbon dioxide is removed from the alveolar capillaries during exhalation and exchanged for oxygen. C.) The venules collect deoxygenated blood from the veins. D.) Ventilation is the movement of gases through a semipermeable membrane. - ANSWER Carbon dioxide is removed from the alveolar capillaries during exhalation and exchanged for oxygen. -Carbon dioxide is removed from the alveolar capillaries during exhalation and exchanged for oxygen. The primary unit of gas exchange is the A.)acinus. B.)terminal bronchioles. C.)primary bronchi. D.)trachea. - ANSWER acinus. -The acinus is the primary unit of gas exchange. Stephan suffers from emphysema. During inspiration you would expect that A.) the pectoral mu
