Week 4: Cognition, Sleep and Pain Flashcards
(185 cards)
what is cognition?
all processes that refer to human thought
how people are aware of their our surrounding
how information is received, processed, stored and then used
what is the definition of cognition according to Giddens textbook?
the mental action or process of acquiring knowledge and understanding through thought, experience and the senses.
what are the six domains of cognitive function?
Perceptual motor function
Language
Learning and memory
social cognition
complex attention
executive function.
how does perception connect to cognition?
mind, brain and information processing
interpretation of the environment
related to awareness, consciousness
depends on sensory input
attention is directed on a particular area
what is memory?
retention and recall of the past
what are the different types of memory?
declarative episodic memory - specific events
declarative sematic memory - knowledge, words, facts
^ these two are long term
immediate memory attention span - short term
working memory - small amt of info can be recalled
procedural memory - muscle memory
what falls under the executive function?
higher order thinking: flexibility, adaptability, goal directedness
determines contents of consciousness
supervises voluntary activity
future oriented
what are the different levels of cognition?
higher order cognitive function - learning, comprehensive, problem solving
basic order cognitive function: perception pattern recognition
cognitive impairment: mild, moderate and severe
what are some risk factors for cognitive impairment?
advanced age
brain trauma
disease or disorder
environmental exposure
substance use disorder
genetic diseases
depression
medications
fluid and electrolytes imbalance
what are some consequences of cognitive impairment?
loss of short and or long term memory, impaired language skills, delusions and hallucinations, uncontrollable or inappropriate emotions such as severe agitation and aggression, impaired reasoning and decision making ability
What are some general management related to cognition?
Primary prevention - ex. how can we avoid drugs that cause this?
Secondary prevention (screening)
Collaborative management
Pharmacologic Agents (meds)
Family and Caregiver Support
What falls under Primary Prevention?
- promote a healthy lifestyle
- Genetic counselling (how genetic conditions might affect you or your family)
- Educating healthcare providers about latest evidence (ex. catheter use, patients restraint)
What are the two screening tool that can be used? (secondary prevention)
General Survey
Glasgow Coma Scale (GCS)
Mini Mental (you will learn in Older Client)
Where in the General Survey does observation of cognition fall into?
Physical appearance - level of consciousness (LOC)
How do you assessing level of consciousness?
Found in: general survey
in the hospital - Alert and oriented - A&Ox4
person, place, time and context
easily follows commands (hand grasps quick and easy)
Explain what falls under Alert and Oriented x4?
Alert - awake and readily aroused, oreintedx4, responds appropriately
Lethargic(Somnolent-sleepy) - drifts off to sleep when not stimulated, looks drowsy, aroused when name called, thinking slow/fuzzy, looses train of thought
Obtunded: Mainly asleep, difficult to arouse - loud shout or vigorous shake, confused, speaks in monosyllables, mumbled/incoherent
Stupor (semicoma) - Spontaneously unconscious, responds only to pain or vigorous shake, withdraws from pain, groan, mumbles
Coma - Completely unconscious, no response to pain
What is the difference between A&Ox4 and A&Ox2
A&Ox4 - alert and oriented to person, place, time and situation
A&Ox2 - alert and oriented to person and place, but does not know the time and what’s happening to them
What is the Glasgow Coma Scale?
responses from: eye opening, verbal and Motor
scores - eyes: 1-4 points
verbal - 1-5 points
motor - 1-6 points
Minor brain injury- 13-15 points
Moderate brain injury - 9-12 points
Severe Brain injury - 3-8 points
8 or less = intubate, no longer can control breathing
what are some responses to painful stimuli?
Localizes
Withdraws
grimances (making a face)
Abnormal posture (decerebrate posture - results from damage to brains stem, Decorticate - results from damage to one of both corticospinal tracts)
No response, flaccid(soft and hanging loosely or limply)
What would decerebrated and decorticate posture look like?
decerebrate- arms are adducted (towards midline) and extended, wrist inward with fingers flexed, legs are stiffly extended with plantar flexion of feet
Decorticate - arms are adducted and flexed, wrists and fingers flexed on the chest, legs are stiffly extended and internally rotated and plantar flexion of feet
which type of posture is most serious and indicated a poorer prognosis?
Decerebrate posture
what is the Mini Mental State Examination?
used to assessment cognitive disfunction (learn more in older client)
true of false: cognition impacts all areas of healthcare

true of false: collaborative approach is a critical element for communication and determining care plans
