NU 272 Exam #1
1. Sensory perception definition conscious process of selecting, organizing, and interpreting
from the senses into meaningful information. perception is
influenced by the intensity, size, change, or representation
of stimuli as well as past experiences, knowledge, and atti-
tudes.
2. stimulus agent or act that stimulates a nerve receptor
3. Receptor nerve cell that acts as a receptor by converting the stimulus
to a nerve impulse
4. impulse conduction impulse travels along a nerve pathway, directly to the brain
5. perception awareness and interpretation of stimuli
6. adaptation when the body adapts to constant sensory stimuli to the
point where it goes unnoticed
7. sensory deprivation decreased stimuli, people unable to process stimuli, de-
pressed patients
8. sensory overload environments that are new, lots of sounds or sensory stim-
ulation, pain, nervous system overloads
9. external stimuli visual, auditory, olfactory, gustatory
10. internal stimuli kinesthesia, stereognosis, inside the body
11. RAS system monitors and regulates all sensory stimuli we come into
contact with. maintains, enhances, inhibits cortical arousal.
responsible for helping our bodies respond to stimuli we
come into contact with.

, NU 272 Exam #1
Alterations of sensory percep- -Hearing impairment
tion -Cataracts
-Eye injury
-Glaucoma
-Macular degeneration
13. things to consider when pa- communication, additional physical requirements for mobil-
tients exhibit sensory alter- ity, time required to provide assistance with routines during
ations hospitalization, acknowledgement of the individual needs
14. nonmodifiable risk factors to premature birth, older age, genetic predispositions
sensory perception
15. modifiable risk factors to senso- smoking, UV light (increase cataract risk), stress (sensory
ry perception overload), injuries, medications, isolation
16. how often should a person get a every 2 years for someone age 40 and up. someone with
vision screening? hypertension or diabetes may go more frequently.
17. tympanic membrane should be translucent and pearly grey
18. subjective findings for sensory - patient history
perception - questions identifying risk factors
- include family members in interview when permitted by
patient
19. visual acuity screenings snellen chart (distance vision) or Rosenbaum (near vision)
20. 6 cardinal fields of gaze wagon wheel or H method, assessing for nystagmus or
strabismus
