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."
The Correct Answer is C
A) Incorrect. Pulmonary embolism does not directly affect the bronchial tubes or cause airway constriction.
B) Incorrect. While inflammation can occur as a response to pulmonary embolism, its primary impact is on blood flow, not the alveoli.
C) Correct. The main effect of pulmonary embolism is the disruption of blood flow to lung tissue, reducing oxygen supply.
D) Incorrect. Excessive mucus production is not a characteristic effect of pulmonary embolism.
