A client with a history of atrial fibrillation has experienced a TIA. In an effort to reduce the risk of cerebrovascular accident (CVA), the nurse anticipates the medical treatment to include which of the following?
A) Cholesterol-lowering drugs
B) Anticoagulant therapy
C) Monthly prothrombin levels
D) Carotid endarterectomy
B
Feedback:
Anticoagulant or antiplatelet therapy can prevent clot formation associated with cardiac dysrhythmias such as atrial fibrillation. Cholesterol-lowering drugs can be ordered if indicated to manage atherosclerosis. Prothrombin and international normalized ratio (INR) levels may be ordered to monitor therapeutic effects of anticoagulant therapy. Carotid endarterectomy would be anticipated only when the carotids have narrowing from plaque.
