After having a pulmonary angiogram, a client is diagnosed with a pulmonary embolism (PE). Which intervention is most important for the nurse to include in the client's plan of care?

A. While pain management is important, it is not the most critical intervention compared to monitoring for bleeding, which can be life-threatening. B. Teaching the client how to use incentive spirometry is important for improving lung function and preventing complications like atelectasis. However, in the context of a pulmonary embolism (PE), the immediate priority is to monitor for signs of increased bleeding due to the anticoagulant or thrombolytic therapy often used to treat PE. This is crucial to prevent potentially life-threatening complications. C. Confusion and restlessness could indicate hypoxia, which is important to monitor in a PE patient. However, the immediate risk of bleeding due to anticoagulation therapy takes precedence. D. Patients with a pulmonary embolism are typically treated with thrombolytic or anticoagulant therapy to prevent further clot formation and to help dissolve the existing clot. Anticoagulants significantly increase the risk of bleeding, making it crucial to monitor for signs of increased bleeding as a priority in the plan of care.
