Which of the following terms refers to a sudden and severe disruption of blood flow to the brain?

The term that refers to a sudden and severe disruption of blood flow to the brain is "Cerebrovascular Accident." This medical event is commonly known as a stroke, which occurs when blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Without timely treatment, brain cells begin to die within minutes, which can lead to lasting disabilities or even death.

A cerebrovascular accident can occur due to a variety of reasons, including a blockage in the arteries that supply blood to the brain (ischemic stroke) or the rupture of blood vessels (hemorrhagic stroke). Understanding this condition is crucial for caregivers, as recognizing the signs and symptoms of a stroke (such as sudden confusion, difficulty speaking, or balance issues) can be life-saving and lead to prompt medical intervention.

The other choices relate to different medical situations that do not involve a sudden interruption of blood flow to the brain. Chronic Obstructive Pulmonary Disease is a long-term lung condition, Cardiopulmonary Resuscitation is a lifesaving procedure used in emergencies, and Do Not Resuscitate is a legal order regarding medical intervention. These are important concepts but do not specifically address the acute nature of the disruption of blood flow to
