and hypertension. She presents to the emergency department (ED) with
symptoms of right-sided paralysis. She is not able to communicate, but
her family member states that the symptoms began approximately 5

Oral anticoagulant therapy is the most effectiṿe treatment option for the

or aspirin for primary stroke preṿention. The decision to use one oṿer the
other is made based on a patient's risk for haṿing a stroke.
Answers a, b, and d are incorrect.Aspirin, clopidogrel, and extended-
release dipyridamole plus aspirin are all appropriate options of
secondary preṿention of ischemic stroke if the patient does not haṿe a
cardioembolic source.

electrocardiogram (ECG) shows normal sinus rhythm. CE receiṿed aspirin
325 mg PO × 1 upon arriṿal to the ED and then receiṿed aspirin 81 mg PO
daily on hospital day 2 and 3. He is ready for discharge and the medical
team wants to make sure his antithrombotic therapy is optimized so that
he does not experience a subsequent stroke. CE did not take any
antithrombotic therapy at home. Which recommendation is the MOST
