ISPN考试模拟试题(215)

Question:

A client is admitted to the hospital with a diagnosis of a pulmonary embolism. Which of the following problems should the nurse address first?

1. Nonproductive cough.

2. Activity intolerance.

3. Difficulty breathing.

4. Impaired gas exchange.

 

Emboli obstruct blood flow, leading to a decreased perfusion of the lung tissue. Because of the decreased perfusion, a ventilation-perfusion mismatch occurs, causing hypoxemia to develop. Arterial blood gas analysis typically will indicate hypoxemia and hypocapnia.

A priority objective in the treatment of pulmonary emboli is maintaining adequate oxygenation. A nonproductive cough and activity intolerance do not indicate impaired gas exchange. The client does not demonstrate an ineffective breathing pattern; rather, the problem of impaired gas exchange is caused by the inability of blood to flow through the lung tissue.

CN: Physiological adaptation; CL: Synthesize
Answer:4
