Answer 2

Perception of solidity of objects.

Question 3

What is the purpose of the kinesthetic and visceral senses?

They are the basic internal orienting systems.

Question 4

What is Kinesthesia?

Answer 4

Awareness of positioning of body parts and body movement.

Question 5

What does Visceral pertain to?

Answer 5

Inner organs.

Question 6

What is Proprioception?

Subconscious movements and positions of the body [(independent of vision) touch the tip of nose].

Question 7

Review table 44-3 for sensory deprivation and overload***

Question 8

What are some nursing interventions to prevent sensory alterations?

Answer 8

• Control patient discomfort whenever possible
• Offer care that provides rest and comfort
• Be aware of need for sensory aids and prostheses
• Use social activities to stimulate senses and mind
• Enlist aid of family members to participate in or encourage activities
• Encourage physical activity and exercise
• Provide stimulation for as many senses as possible

Question 9

What are some responses to sensory deprivation?

Answer 9

• Provide meaningful stimulation

- Amplify any sense in a respectful way you can (larger print for vision, pleasant aromas for smell, etc)

Question 10

What are some responses to sensory overload?

Answer 10

• Minimize overall stimuli

- Vice versa of sensory deprivation (reduce unpleasant odors, etc)

Question 11

What is Presbyopia?

Answer 11

Age-related loss of eye’s ability to focus on close objects.

Question 12

What are Cataracts?

Answer 12

Answer 14

Leakage and blockage of retinal blood vessels.

Question 15

What is Macular Degeneration?

Answer 15

Deterioration of center of retina.

Question 16

What does the Rinne test determine for conductive hearing loss?

Answer 16

Air conduction of sound less than or equal to bone conduction. (AC < or = BC).

Question 17

What does the Rinne test determine for sensorineural hearing loss?

Answer 17

Expected response of air conduction being greater than bone conduction, but with length of time decreased for both (AC >BC).

Question 18

What is the purpose of the RAS?

Answer 18

• Mediates arousal

- Allows all impulses to reach cerebral cortex and be perceived

Question 19

What is sensoristasis?

Answer 19

The optimal arousal state of RAS.

Question 20

What is the order for sensory perception to be successful?

Answer 20

• Presence of stimulus
• Conversion to a nerve impulse
• Conduction from receptor to brain
• Translation into a sensation.
