knowledge assessment III Flashcards
skeletal structure
cranium is composed of 22 bones supporting the soft tissue structures of the head
anatomy of head
contains:
- muscles
- blood supply
- nerve supply
- salivary glands
blood supply to the head
- carotid arteries
- temporal artery
- internal and external jugular veins
nerve supply to face
cranial nerve V - facial nerve
salivary glands
parotid
submandibular
sublingual
CN VIII can interfere with
vestibulocochlear nerve can interfere with balance
facial nerve innervates ear which can
interfere with balance
facial muscles are responsible for
all movement of the face
CN V responsible for movement
any injury to ear
effects coordination and hearing
brainstem injury
very disoriented and confused
anatomy of the nose
- allows air to enter the respiratory tract
- primary organ for smell
- nerve and blood supply consits of CN 5, 7, 9, and 10, internal and external carotid arteries, and kiesselbach plexus
- lymphatic drainage
kiesselbach plexus
blood supply to the nose, most common for nose bleeds
ethmoid bone
only bone separating brain from nose
if ethmoid bone breaks
risk for infection, leakage of cerebrospinal fluid
sigmoid bone
helps protect against infection
sinuses all come together to form
osteomeatal complex
sinus anatomy
frontal sinus
maxillary sinus
ethmoid sinus
most common site of anterior nose bleeds
kiesselbach
common in cases of trauma, should stop with pressure
mouth
- eat, taste, chewing, speech
- very vascular tongue
- salivary glands
- teeth and gums
vascularity of tongue allows for
sublingual meds
quick acting meds
tongue
- muscle (most vascular muscle)
- front 2/3 should be covered in tastebuds
salivary glands
- produce 2-4 L/day of saliva
- affected by aging and certain meds, xerostomia, chemo
issues with salivary gland causes
harder to swallow food, and protection
xerostomia
dry mouth
teeth and gums
- 32 full grown adult teeth
- dentures
- state insurance and medicate may not include dental care
C1-C7
helps support neck
C3, C4, C5 …
keep lungs alive
will not be able to breathe on own if injured
neck is composed of
- vertebrae
- muscles
- trachea
- thyroid and parathyroid glands
- lymphatics
- throat
- tonsils and adenoids
neck muscles
sternocleidomastoid and trapezius contribute to use of accessory muscles for breathin
tracheal deviation
- should be midline
- should not be painful, or deviated
- if deviated s/o lung collapse
thyroid
should not be felt
should be sticking out
hypothyroidism
fatigue, high BP, increase in BW
hyperthyroidism
decrease wiehgt, increase BP, increase HR, increase metabolism
posterior auricular lymph nodes
behind ear
occipital lymph nodes
base of head posteriorly
superficial cervical lymph nodes
lower ear and parotid
deep cervical lymph nodes
other nodes of head and neck, occiptal scalp, ear, back of neck, tongue, trachea, nasopharynx, nasal cavities, palate, esophagous
posterior cervical lymph nodes
in between sternocliedomastoid and traps
supraclavicular lymph nodes
thorax and abdomen
preauricular lymph nodes
in front of ear
parotid lymph nodes
below ear, on parotid gland
tonsillar lymph nodes (jugulodiagastric)
at jawline
submental lymph nodes
lower lip, floor of mouth, apex of tongue
submandibular lymph nodes
cheek, side of nose, lower lip, gums, anterior tongue
if lymph nodes are palpable..
could be signs of infection or cancer
if lymph nodes arent draining
gets larger
tonsils
pain, breathing, swelling, infection
older adult considerations for H&N
- facial skin becomes less elastic
- bony structures are more pronounced causing alteration in facial appearance
- hair begins to thin (may be related to thyroid)
- spinal structure may become concave and reduced ROM in neck can appear
- hypothyroid is common in pts 60+, all older adults should be evaluated
- gustatory rhinitis (clear rhinorrhea stimulated by smell and taste of food)
- decreased olfactory sensory fibers
- thinning of soft tissues of oral cavity - increased risk of ulcer, infection, and oral CA
- decreased enamel on the teeth - gums beging to recede and teeth appear larger (increased bone resorption and teeth may loosen, brittle teeth, may break, may need implants or dentures, may need altered diet due to dentition change)
- smooth glossy tongue may result from deficiencies in different B vitamins
vitamin B impacts
brain function
cultural variations and health disparities for H&N
- shape and size of facial features, head and neck
- females have higher risk of both hypo and hyper thyroidism
- oropharyngeal cancer occurs more frequently in economically developed countries
- oral disease higher amongst those of low socioeconomic status
- congenital defects in children
- head and neck cancer (high risk with HPV infection)
- sleep disorderd breahthing (2x-4x more MI or stroke)
- cavities increase among decrease socioeconomic status
priority urgent assessment H&N
- acute head and neck injury (C-spine stabilization is priority, assess for neurologic changes)
- obtain H&P
- neck pain
- lymph node assessment
- thyroid assessment
c-spine stabilization
neck not stable, turning can sever spinal cord causing death
educate patients on
wearing helmet
full hx only when pt is
stable
lymph nodes concerns
> 1 cm
hard
rubbery
immobile
thyroid - BMR
increase in BMR is life threatening
called thyroid storm
priority urgent assessment mouth and nose
- epistaxis
- post-op bleeding after tonsillectomy
- ludwig angina
- aspiration risk
- ansomnia
- anaphylaxis and airway obstruction
epistaxis
- nosebleed
- posterior nose bleed, no pressure works, likely to swallow blood and experience n/v
- 3-5 days of tubing
tonsillectomy
increased risk of bleeding
hypotensive
tachycardic
ludwig angina
swelling of tongue
aspiration
food/fluid in lungs
increased risk after stroke (sit up, assess ANOx4)
silent aspiration is more dangerous
anosmia
loss of smell
signs of neuro issue (early sign of parkinson)
viral
anaphalyaxis
airway
!emergent!
subjective data collection for head and neck
- assess risk factors (health promotion and educational opportunity)
- past medical hx
- lifestyle and personal habits
- dental health
- substance use hx
- environmental exposure
- meds or allergies
- family hx
teaching and health promotion
- tobacco use (always assess interest in quitting)
- sleep disorders (insufficient sleep = poor brain development)
- cancer (risks)
- oral health
- hereditary hemorrhagic telangiectasia
- headache or facial pain
- limited ROM of neck
- lumps of masses
- hypo/hyperthyroidism
hereditary hemorrhagic telangiectasia
malformations of vessels in body causing increased risk of bleeding
nose bleeds is common sign (use humidifiers and saline)
objective data collection
- inspect head, neck, mouth, hair, and throat
- evaluate swallowing
- assess aspiration risk
- vision test
- hearing test
sinus cultures indicate
sinusitis
biopsies are done in
cases where lymph nodes can be palpated
lab values - cbc for wbc, thyroid levels
infection, TH levels
radioallergosorbent testing (rast) for allergies
skin testing
xray
observe bones
CT scan and MRI
observe soft tissue
xray ct scan and mri
observe structural abnormalities
sleep studies
sleep apnea
prioritize hypotheses and take action
- cluster data and ID patterns
- nose, sinus, mouth, throat (impaired airway clearance, impaired swallowing, sleep deprivation
- head and neck (activity intolerance, fatigue, chronic pain)
anatomy of neurological system
composed of central and peripheral nervous system
central nervous system
- composed of brain and spinal cord
peripheral nervous system
composed of cranial and spinal nerves
the cerebrum
- right and left hemisphere which control motion of opposite side of body
- composed of four lobes; frontal, parietal, occipital, temporal
frontal lobe
personality, behavior, emotions, intellectual function (broca’s area- mediates speech)
parietal lobe
sensation
occipital lobe
visual reception
temporal lobe
auditory reception (hearing), taste, smell
wernicke’s area - language comprehension
hypothalamus
- respiratory center, temperature regulation, appetite, sex drive, heart rate, BP regulation
- regulates anterior/posterior pituitary (hormone regulation)
traumatic injury to frontal lobe can lead to
impulsive changes in personality and sometimes memories
impaired hypothalamus causes
vital signs to be abnormal
cerebellum
motor coordination of voluntary movements, equilibrium muscle tone, walking, balance, ADLs
brainstem regulates
primitive reflexes (coughing, gagging, HR, BP)
neuro change =
cardiac change
ascending spinal cord
carries sensory information
descending spinal cord
sends motor information
neurons
- basic functional unit of nervous system
- receives/transmits electrochemical nerve impulses
- afferent and efferent neurons
afferent neurons
sensory neurons
carry impulses from the body to the CNS
efferent neurons
motor neurons
carry impulses from the CNS to the body
responds to afferent neuron stimulation
peripheral nervous system
- all the nerves outside the brain and spinal cord
- relays messages from brain to the rest of the body
- cranial nerves
- spinal nerves
cranial nerves
- 12 pairs that exit from the brain
- sensory, motor, or both
spinal nerves
- arise from spinal cord and innervate the rest of the body
- 31 pairs
c1-c6 contain
most of spinal nerves
if spinal cord injury to c1-6
pt may have difficult time breathing
