RNRS: 117 SENSORY ALTERATIONS (CHAPTER 49) EXAM
QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS
Senses
-senses of sight (visual)
-hearing (auditory)
-touch (tactile)
-smell (olfactory)
-taste (gustatory).
Kinesthetic
the sensation of movement or strain in muscles, tendons, and joints; muscle sense.
Stereognosis
ability to recognize objects by feeling their form, size, and weight while the eyes are
closed
Normal Sensation: Reception
stimulation of a receptor such as light, touch, or sound
Normal Sensation: Reaction
only the most important stimuli will elicit a reaction
Normal Sensation: Perception
integration and interpretation of stimuli
Normal Hearing and Vision-Ear
, Ear
-Transmits to the brain a pattern of all sounds received from the environment, the
relative intensity of these sounds, and the direction from which they originate
Eye
-Transmits to the brain a pattern of light that is reflected from solid objects in the
environment and becomes transformed into color and hue
Sensory Alterations
-Sensory deficits
-sensory deprivation
-sensory overload
Sensory deficits
impaired or absent functioning of one or more senses
Hearing deficits
Older people tend to hear low frequencies well but suffer hearing loss when listening for
high frequencies.
-Presbycusis: A common progressive hearing disorder in older adults.
-Cerumen accumulation: Buildup of earwax in the external auditory canal
Visual Deficits
Presbyopia-A gradual decline in the ability of the lens to accommodate or focus on
close objects. Individual is unable to see near objects clearly.
Cataract-Cloudy or opaque areas in part of the lens or the entire lens that interfere with
passage of light through the lens, causing problems with glare and blurred vision.
