63
Q

Reorient frequently
Encourage visitors and social stimulation
Temporary change of environment if possible- sit by window, take outside
Provide large-print materials or electronic players
Provide pleasant aromas
Ensure use of assistive devices

64
Q

Sensory Overload

A

Excessive stimuli prevent the brain from responding to or ignoring certain stimuli.

Overload prevents meaningful response by the brain.

A person’s tolerance to sensory overload can vary according to fatigue, attitude, and physical and emotional well-being

It is easy to confuse the behavioral changes associated with sensory overload with mood swings or simple disorientation.

65

Q

Sensory overload symptoms

A 
Fatigue
Sleepiness
Irritability
Disorientation

Restlessness
Anxiety
67
Q

Control of excessive stimuli
Provide dark glasses and earplugs
Control pain
Unhurried manner, low voice
Assist with stress-reducing techniques
Allow for uninterrupted rest periods
Schedule routine of care and prepare client for procedures
Limit visitors
Provide new information gradually
68
Q

Nursing care :Acute care
