RNRS 396 Med Surg ATI Study Guide- Azusa Pacific University

Med-surge ATI: I. NERVOUS SYSTEM: 1. Cerebral Angiogram: - Allows for visualization of cerebral blood vessels. A catheter is placed into an artery (usually in the groin) and threaded up the blood vessels in the brain, dye is injected, x-ray are taken.  Pre-procedure:  NPO 4-6 hrs prior.  Assess for allergy to iodine or shellfish.  Assess kidney function (BUN, creatinine) to determine if kidneys can excrete the dye.  Post-procedure:  Check insertion site for bleeding, check extremity distal to puncture site (pulses, capillary, refill, temperature, color) 2. EEG: - Analyzes electrical activity in the brain. It is used to identify seizure activity, sleep disorders, behavioral changes. 1 hrs. - Pre-procedure patient instructions:  Wash hair prior to procedure  Arrive sleep-deprived (as this increases chance of seizures)  No NPO is needed. Avoid stimulates, sedative medications 12-24hrs before procedure.  Flashing light, hyperventilate (to increase electrical activity) 3. Intracranial pressure (ICP) monitoring: RANGE 10-15 mmHg. - Inserted into cranial cavity in the OR to measure pressure. HUGE RISK OF INFECTION.  GCS score of 8 or less or coma  SYMTOMP:  Irritability (early sign!),  Restlessness, headache, decreased LOC  Pupil abnormalities, abnormal breathing ( EX: Cheyne Stokes)  Abnormal posturing
