Intravenous tissue plasminogen activator (IV tPA) is a protein that is used to break up blood clots. A blood clot that forms in an artery can block the flow of blood “downstream.” Areas of brain that rely on the now-blocked blood vessel become starved for oxygen. When a part of the brain is starved for oxygen, it is called ischemia or a stroke. The area of brain where the stroke occurs de- termines the resultant neurologic problems. For instance, if the stroke occurs in a region of brain that controls movement, the person becomes weak. When a stroke happens, the use of tPA can open the blood vessel and restore proper blood flow to the brain. Treatment with IV tPA can minimize the damage from a stroke by allowing blood and oxygen to reach its destination. Stroke is a common neuro- logic condition. It is estimated that stroke occurs in 2.5%–2.7% of people living in the United States or one of its colonies (data from 2006 to 2010: the Centers for Disease Control and Prevention1). Sur- prisingly, fewer than 5% of patients with ischemic stroke receive treatment with IV tPA.2 Many factors may affect the use of tPA. For instance, tPA mu
