Transcript lecture 3 mental status

Inspection
 Purpose: Assess function for ability to perform ADL’s
 Inspect for symmetry, proportion, and muscular
development
 Observe gait, stance, and ability to stand, sit, rise from
sitting position, and grasp objects
 Inspect muscle for symmetry
 Inspect joints for symmetry, swelling, tenderness, and
crepitation
 Test muscle strength upper and lower extremities utilizing
opposing force
Palpation
 Palpate large and small joints
 Assess range of motion ROM
 Decreased ROM
◦ Arthritis, fibrosis, tissue inflammation, and fixed joints

Increased ROM
◦ Increased joint mobility and joint instability



Limitation in ROM are expressed in degrees
Palpate joints and surronding area for tenderness
Assess for warmth, crepitation, and deformaties

Appearance:

A summary of the physical presentation to paint a
clear mental portrait
◦ Dress, facial expression,
◦ Posture, eye contact
◦ Hygiene and Grooming
–“Disheveled”- ruffled appearance
–“Unkempt”- poor attention to grooming
◦ Body habitus, nourishment status
 General description of body type/ build, and
nutritional status
Motor Activity:
 quality and the types of actions observed
◦ reduction in the level of movement (psychomotor
retardation)
◦ slowed movement (bradykinesia)
◦ decreased movement (hypokinesia)
◦ absence of movement (akinesia)
◦ increases in the overall level of movement
(psychomotor agitation)
◦ tremor

Range and Frequency of Spontaneous Movements
– Psychomotor activity
◦ Abnormal movements

Psychomotor refers to movements that appear driven
from within, by one’s internal emotions at the time
– Psychomotor Agitation, vs.
– Psychomotor Retardation

Automatisms- “automatic” involuntary movements;
form of seizure
◦ Ex. Lip-smacking, eye-blinking, fumbling with clothing,
staring

Mannerisms: goal-directed, complex behaviors carried
out in an odd way or inappropriate context
Behavior
◦ level of consciousness extending from alert
through, drowsy, a clouding of consciousness,
stupor (lack of reaction to environmental stimuli)
and delirium (bewildered, confused, restless, and
disoriented), to coma (unconsciousness
◦ degree of arousal (e.g., hypervigilance to
environmental cues and hyperarousal such as
observed in anxious and manic states)
◦ mannerisms (e.g., tics and compulsions).
Attitude:
 Identifiers may be open,
◦ Friendly, Cooperative, willing, and responsive on the hand
◦ Closed, guarded, hostile, suspicious, passive

Describe attentiveness, responses to questions,
expression, posture, eye contact, tone of voice
Mood and Affect
 Affect (an external expression of an emotional state)
is potentially observable
 Mood (internal emotional experience that influences
perception of the world and behavioral responses)
Mood and Affect
 Is the patient’s mood appropriate to situation?
 Sad, Angry, Depressed, Anxious
 Restricted (reduced), Blunted (greater
reduction), Flat (absence or near absence of
any affect)
 Appropriate/Inappropriate
 Labile
Mood and Affect
 Descriptors: euphoric, dysphoric, hostile,
apprehensive, fearful, anxious, suspicious
◦ Stability of mood can also be noted, with the
alternation between extreme emotional states being
referred to as emotional lability
Mood and Affect
◦ Range, intensity, and variability of affect can be variously
portrayed:
 restricted (i.e., low intensity or range of emotional
expression)
 blunted (i.e., severe declines in range and intensity of
emotional range and expression)
 flat (i.e., absence of emotional expression,)
 exaggerated (i.e., an overly strong emotional reaction)
◦ Appropriateness (expression incongruent with verbal
descriptions and behavior)
◦ General responsiveness
Level of Consciousness – LOC
 Alert: Awake, answers questions
 Lethargic/Somnolent: Sleeps when undisturbed, arouses to
normal voice, answers questions appropriately –may be
“fuzzy”
 Obtunded: Sleeps most of time. Loud shout or vigorous
shake to arouse. Speaks in monosyllables, mumbles.
 Stupor/Semi-coma: Responds only to vigorous shake or
pain. Groans, mumbles, moves restlessly. Withdraws to
avoid pain/noxious stimuli
 Coma: Un-responsive to any stimulus


We test attention by seeing if the patient can remain focused
on a simple task, such as spelling a short word forward and
backward (W-O-R-L-D / D-L-R-O-W is a standard),
repeating a string of integers forward and backward.
Normal digit span is 6 or more forward, and 4 or more
backward, depending slightly on age and education.
These tests of attention depend on language, memory, and
some logic functions as well.
Degree of cooperation should be noted, especially if it is
abnormal, since this will influence many aspects of the
exam.

Person, place, date/time, event
Time is the first to go, person the last.
Normal: Expressed as oriented x3
Disoriented? All parameters or 1 or 2?
Does client re-orient?
Is this a change from baseline?
Document level of orientation along with descriptive
statements supporting abnormal findings.
Have the patient repeat a specific phrase
Note his speech during the whole exam process.
 Clear, Slurred, Garbled
 Minimal (mostly "yes" and "no" answers, little
volunteered information)
 Talkative
◦ Rapid/Pressured (as in possible hypomania or
mania


Described in terms of:
◦ Rate (e.g., slow, rapid)
◦ Intonation (e.g., monotonous)
◦ Spontaneity
◦ Articulation
◦ Volume
◦ Quantity of information conveyed
 mutism (i.e., absence of speech)
 poverty of speech (i.e., reduced spontaneous speech)
 pressured speech (i.e., rapid speech that is hard to interrupt
and understand)
Language includes reading, writing, and comprehension.

Immediate
◦ Say a list of single digit numbers and ask patient to repeat them

Short term
◦ Have the patient memorize 3 unrelated words and ask him to
repeat them later.

Long-term memory
◦ ask the patient about a known historical event that happened in
his life time.


Insight : a dimension that describes the extent to which clients
are aware that they have a problem
◦ A strong lack of insight can be an important indicator of
unwillingness to accept treatment
◦ Insight refers also to an awareness of the nature and extent
of the problem, the effects of their problem on others, and
how it is a departure from normal
Judgment: The ability to make sound decisions can be
compromised for a number of reasons
◦ ascertain if poor decisions are the result of problems in the
cognitive processes involved in the decision making
process, motivational issues, or failures to execute a planned
course of action
See table 4-9
 I - OLFACTORY
◦ Don’t assess unless patient complains of loss of
sense of smell or patient has a head injury
◦ Don’t use a noxious stimulus

◦ Visual fields
◦ Fundoscopic exam ( eye exam)


