A patient with an embolic stroke is being cared for by the nurse. When developing the teaching plan for this patient, the nurse considers which of these factors in the patient's history as the greatest risk for this type of stroke?
1. deep-vein thrombosis
2. hypertension
3. use of anticoagulants
4. atrial fibrillation
4
Rationale: Atrial fibrillation, in addition to endocarditis, rheumatic heart disease, and recent myocardial infarction, are the most common causes of embolic cerebral vascular accidents. Use of anticoagulants and hypertension together are associated with hemorrhagic cerebral vascular accidents. Hypertension is also associated with thrombotic strokes. Deep-vein thrombosis alone is not a risk.
