The family of a patient who experienced a stroke after percutaneous coronary revascularization asks the nurse what caused the stroke to occur. How should the nurse respond to the family?
1. "A stroke could have been caused by clot particles from the procedure."
2. "Stroke is usually caused by ruptured plaque inside the coronary artery."
3. "Stroke is caused by heart failure."
4. "No one knows what causes strokes."
Correct Answer: 1
After percutaneous coronary revascularization clot particles can migrate leading to a stroke. Plaque inside a coronary artery would travel downstream and lodge in a smaller vessel in the heart. Heart failure does not cause a stroke. Stating that no one knows what causes strokes is not a true statement; blood clots and ruptured vessels cause strokes.
