_______ is associated with blood vessels and not the fluid within the ventricles of the brain. Localized ischemia with areas of necrosis noted on CT angiography is incorrect in that there is blood flow to the area. Ischemia is associated with decreased arterial flow resulting in the death of brain tissue. In arteriovenous malformations, a tangle of arteries and veins acts as a bypass between the cerebral arterial and venous circulation, in place of the normal capillary bed. However, the capillaries are necessary to attenuate the high arterial blood pressure before this volume drains to the venous system. As a result, the venous channels experience high pressure, making hemorrhage and rupture more likely; the lack of perfusion of surrounding tissue causes neurologic deficits such as learning disorders. Headaches are severe, and people with the disorder may describe them as throbbing (synchronous with their heartbeat). Increased tissue profusion means that more oxygenated blood is brought to the area, which is not the case. The elevated arterial and venous pressures divert blood away from the surrounding tissue, impairing tissue perfusion. A. ischemic stroke B. arteriovenous malformation C. Tribbing malfromation

B. arteriovenous malformation

Passive helper cells B. tumor necrosis factor-a and IL-1 C. CD4 T helper

Whether the client has a family history of seizure disorders is not relevant to the treatment being administered. The type of seizure activity and the client's allergies to medications is important for the nurse to determine, but these will not inform the treatment plan to the same extent as knowing the client's medication history. A client with a history of ______ is brought to the emergency department due to seizure activity. This is the information about the client is most important for the nurse to collect. A. epilepsy B. Seizures C. MS
