CN VIII (Acoustic)

Which Cranial Nerve? Voice Quality

CN X (Vagus)

Which Cranial Nerve? turns head and elevates shoulders

CN XI (Spinal Accessory)

True/False: Mental status remains constant throughout life.

False- age related changes occur during growth and development.

True/False: A person who cannot be woken should be documented as unconscious on the medical chart.

False- this is a non-medical term, refer to proper medical terminology

How do we assess convergence of the eyes?

Move your finger towards the client's nose/eyes should converge (cross-eyed appearance)

When assessing orientation (state of consciousness), you should ask what type of questions to determine mental status?

Person, place & time *What is your name? What is your spouse's name? *Where are you? What is the state capitol? *What day is it? What year is it?

The left (dominant) side

Which side of the brain controls written and spoken language, reasoning, number skills, scientific knowledge and right hand control.

The left side

How do we assess the pupil's accommodation?

The normal pupil constricts when focused on a near object and dilates when focused on a far object

How do you assess the motor function of this nerve?: Ulnar nerve

abduction of fingers (spread fingers apart)

(def)a disorder in processing language

(def)a disorder in programming speech (saying the wrong word)

apraxia of speech

Eye opening is what component of consciousness?

arousal

(def) Loss of the ability to coordinate muscular movement.

ataxia

If a person if fully conscious, we document this how?

awake, alert, and oriented x 4

(def) aware of self and the environment with the ability to focus and interact

awareness

What part of the brain is tested when assessing coordination, smooth movement, and position sense?

cerebellum

Mental status determine ________functioning.

cerebral

What level of consciousness? sleep-like state with eyes closed/ does not respond appropriately to bodily or environmental stimuli/ no verbal sounds

comatose

What level of consciousness? disoriented to time, place, person, or situation/ short attention span/poor memory/ easily bewildered confused

confused

Moving towards a painful stimulus is an action triggered in what part of the brain?

cortex

What are purposeful movements?

direct, specific movements (scratching nose, etc)

What is sixth nerve palsy? How do you assess for it?

double vision- cover one eye, should correct if positive. Offer a patch over the "good" eye

during history

(def) a disorder in the mechanics of speech

dyarthria

(def) a lack of coordination of movement, typified by the undershoot or overshoot of intended position with the hand, arm, leg, or eye

dysmetria

What are non-purposeful movements?

flexion, abnormal extension, fisted hands, flexed wrists, etc.

How do you assess the motor function of this nerve?: Radial Nerve

have client move wrist back and forth

have client perform thumb opposition with remaining 4 fingers

How do you assess the motor function of this nerve?: peroneal nerve

have the client dorsiflex foot (up)

How do you assess the motor function of this nerve?: Femoral nerve

have the client perform a straight leg raise

How do you assess the motor function of this nerve?: Tibial nerve

How do you assess the sensory function of this nerve?: radial nerve

touch the space between the thumb and 2nd finger

True/False: When assessing the patient, you should look for symmetry, therefore you always compare left to right.

true

ulnar nerve

What nerve is commonly injured at the elbow due to elbow fracture or dislocation?

ulnar nerve

Describe how to do a sensory assessment?

use a wisp of cotton and lightly touch one specific spot, and then the same spot on the other side of the body. Patient says yes when cotton if felt.
