The nurse's best response would be b. "An aspirin a day can help prevent some of the blockages that can cause chest pain or heart attacks." While the patient may not have any pain currently, taking aspirin daily can help reduce the risk of developing blockages in the coronary arteries, which can lead to chest pain or heart attacks.
