Sensory Flashcards
abnormal neurological condition in which language function is defective or absent; related to injury to the speech center in the cerebral cortex causing receptive or expressive aphasia
Aphasia
a motor speech disorder resulting from neurological injury of the motor component of the motor-speech system in which a person has difficulty using & controlling the muscles involved in when speaking
Dysarthria
the sensation of movement or strain in the muscles, tendons & joints; muscle sense
Kinesthetic
a continuum existing from fully awake, alert & cooperative to unresponsive to external stimuli
Level of Consciousness
having harmful effect on the eighth cranial (auditory) nerve or the organs of hearing & balance
Ototoxic
hearing loss associated with aging usually involving both loss of hearing sensitivity & reduction in clarity of speech
Presbycusis
gradual decline in ability of the lens to accommodate or to focus on close objects; reduces ability to see near objects clearly (commonly develops with advancing age)
Presbyopia
therapeutic modality for restoring an individual’s sense of the present
Reality Orientation
system located in the upper brainstem containing special cells that maintain alertness & wakefulness; receives auditory, visual, pain & tactile sensory stimuli, activity from the cerebral cortex (emotions or thought processes)
Reticular Activating System (RAS)
state in which stimulation to one or more of the senses is lacking resulting in impaired sensory perception
Sensory Deprivation
state in which stimulation to one or more of the senses is so excessive that the brain disregards or does not meaningfully respond to stimulus
Sensory Overload
nocturnal agitation in a patient with Alzheimer’s or dimentia
Sundown Syndrome
abnormal condition of the upper eyelid in which it droops, caused by weakness in the levator muscle or paralysis of the 3rd cranial nerve
Ptosis
drugs that constrict the pupil
Miotics
drugs that dilate the pupil
Mydriatics
receiving stimulus & data
Sensory Reception
conscious organizing & translation of stimuli/data into meaning
Sensory Perception
The 4 Conditions Necessary in Each Sensory Experience
STIMULUS (agent that can solicit response), RECEPTOR (sense organ that can convert stimuli), IMPULSE TO BRAIN (intact nerve pathway), & SENSATION (brain translates the experience)
Factors Affecting Sensory Function
Developmental Stage, Culture & Environment, Personality & Lifestyle, Stress, Illness, Medication
Patients At Risk for Altered Sensory Function
Nursing Home Patients, Isolated Healthcare Setting or Home Patients, Bed Rest Patients, Hospital Patients (overload)
Nursing Interventions for Disturbed Sensory Perception
Keep Functional & Meaningful Environment, Stimulate the Senses
Nursing Diagnoses for Sensory Alterations
Anxiety, Fear, Impaired Physical Motility, Hopelessness, Risk for Injury, Deficient Knowledge, Impaired Social Interaction, Bathing Self-Care Deficit, Risk for Falls
