Q

What is the process of concentrating on a specific stimulus without being distracted by other, irrelevant stimuli?

24
Q

What is the process of receiving and interpreting sensory stimuli tha function as a basis for understanding, knowning, or learning.

A

perceiving

25
perceiving obtains information through?
- vision - hearing - touching - taste - smell
26
What is the process of sorting, organizing, and categorizing information to form mental concepts or perceptions?
Thinking
27
What is the multidimensional process of acquiring knowledge that depends on abstract functions such as symbols, language, classifications, and concepts as well as concrete operations?
learning
28
Experiences, ideas, and images are chemically coded and intergraded for later retrieval is called?
remembering
29
Communicating is done is serveral ways what are they?
- verbally - nonverbally (through facial expressions) - body posture - movements - gestures - touch
30
All of these factors affect? - blood flow - nutrition and metabolism - fluid and metabolism - sleep and rest - self-concept - infectious process - degenerative process - medication - head trama
cognitive function
31
What is needed to function optimally, all cells need a continuous oxygen supply. Oxygenation depends on resp. and circulatory function and hemoglobin production. (any interruption to the brain cells causes cellular hypoxia, resulting in changes in function)
blood flow
32
What does the brain cells need glucose and other nutrients for?
Nutrition and metabolism
33
brain cells require a constant extracellular environment balance of what?
fluid and electrolyte balance
34
What allows people to regain enegry for cognitive functions, and is necessary for consolidating learning and moving information from short term to long term memory?
sleep and rest
35
What process does the CNS, including encephalitis and brain abscesses, and the subsequent inflammatory response of nerve cells, are obvious causes of altered cognition (confusion and lethargy).
Infectious process
36
What process contributing to degeneration of the brain cells may ultimately affect cognitive function. Causes: organisms, aging, or unknown sources. Can impair judgement, insight, planning, memory, problem solving, and communication.
Degenerative process
37
What can primarily act on the CNS and impair thinking and cause confusion (think benzodiazepines). Also the ones that don’t act on the CNS can also cause confusion, wither alone or in combination.
Medications
38
What communication problems in head-injury patients are usually compounded by impairments in cognitive function, such as behavior, memory, orientation and attention. (falls and motor vehicle crashes are the most common causes.
Head trauma
39
what is an acute change in mentation and represents a high risk to patients? HINT: there are three types: hypoactive, hyperactive, and mixed
delirium
40
Name the types on altered cognitive function:
- delirium - sundown syndrome - schizophrenia - altered level of arousal - altered attention - memory impairment - aphasia - three types:expressive, receptive, anomic, global - dysarthria
41
limited speech that is slow and halting with great effort, reduced grammar, and poor articulation. Has problems with word retrieval is called?
expressive aphasia
42
anomia means?
problems with word retrieval
43
speech is well articulated and has good melody. Impaired auditory comprehension and feedback. Difficulty understanding spoken and written words. They make talk but not make since. Unaware of language impairment. This is called?
receptive aphasia
44
When one speaks fluent, but talks around the subject it is called?
anomic aphasia
45
What results from severe and extensive damage to all language areas. Cannot speak or understand speech, or read or write.
Global aphasia
46
a group of speech disorders that result from a disturbance of motor control, weakness, paralysis, or incoordination of the oral musculature. Usually have normal auditory comprehension and can select and order words correctly. Slurred speech, heavy, or unclear. What is this called?
Dysarthria
47
-normal pattern identification -risk identification -dysfunction identification -physical assessment -diagnostic tests and procedures these are all?
assessments that can identify cognitive process/ function safety
48
The collection of subjective data is?
normal pattern identification
49
flat means?
no sign of emotion
50
labile means?
wide fluctuation in emotions
51
what assess for physiologic, psychological, and environmental factors that increase the likelihood of impaired cognitive processes?
risk identification
52
When identifying dysfunction use?
clear information identifying the dysfunction.
53
Physical assessment provides?
clues as to the source of altered cognitive process. - 02 levels - electrolytes - metabolic by products lethargy, mild confusion, impaired thinking - lab evaluation - assess!!!!!! everything
54
Arterial oxygen levels should be above?
60mm hg
55
Electrolyte levels should be between?
8.5 and 10.5 mg/dl | if it exceeds 14mg confusion is common
56
Ammonia and urea are potentially toxic by products of?
protein metabolism
