    1. NURS2520 Health Assessment II Unit Five Neurological Assessment

    2. Objective One Assess the components of the basic neurological assessment

    3. Neurological System Functions through transmission of chemical and electrical signals between the body and the brain Receives, processes, and sends out information Controls and coordinates the functioning of all other systems in response to environment/surroundings Involves cognition, emotion, memory, sensation and perception, and regulation of homeostasis Comprised of the central nervous system (CNS) and the peripheral nervous system (PNS) CNS = Brain and spinal cord PNS = Cranial and spinal nerves

    5. Two neurons with synapse (from MyNursingLab)

    7. Brain and spinal cord (from MyNursingLab)

    8. Age-Related Considerations Birth reflexes include rooting, sucking, palmar grasp, tonic neck reflex, and Moro Disappear during infancy May return w/stroke or trauma Denver Developmental Screening Test II (DDST) used to screen young children Neurons decrease over lifetime, resulting in slowed reaction time, problem-solving skills, and voluntary movement Decreases in intelligence and memory not normal in the elderly, and indicate a neurological deficit Medication effects, dehydration, Alzheimer’s dementia, etc

    9. Cerebral Function Level of consciousness (LOC) Arousal (alert, lethargic, stuporous, comatose) Verbal stimuli Tactile stimuli Painful stimuli Orientation (person, place, time) Mental status and cognitive function Behavior, appearance, response to external stimuli, speech, recent and remote memory, communication, judgment Posture, gait, motor movements, dress, hygiene/grooming, mood, affect, facial expression Consider language/education/culture during neuro exam

    11. Objective Two Demonstrate the proper technique for the assessment of reflex activity

    12. 12 Reflex Function Deep tendon reflex is tested with a rubber percussion hammer to tap a slightly stretched muscle Normal response = muscle contraction Response grading scale: 0 = No response detected +1 = Diminished response +2 = Response normal +3 = Response somewhat stronger than normal +4 = Response hyperactive with clonus Clonus refers to involuntary continuous contractions of a muscle or group of muscles Superficial reflexes are tested by lightly touching the body with the base of a reflex hammer or tongue blade, beginning with the most peripheral part of the limb Graded as positive or negative Determine sensory loss area by testing every 1-2 inches

    14. Objective Three Demonstrate the assessment techniques employed in the assessment of cranial nerves

    15. Dorsal aspect of brain w/cranial nerves (from MyNursingLab)

    19. Objective Four Demonstrate the complete assessment of the neurological system (*Lab Practice) http://www.youtube.com/watch?v=_1Rd1wVeqU4&feature=related
