A nurse is educating a client on how a pulmonary embolism can impact lung function. What should the nurse emphasize regarding the physiological effects?
"A pulmonary embolism directly affects the bronchial tubes, causing airway constriction."
"It primarily causes inflammation in the alveoli, leading to impaired oxygen exchange."
"Pulmonary embolism disrupts blood flow to the lung tissue, reducing oxygen supply."
"The condition leads to excessive mucus production, obstructing the air passages."
