NURS 240 Chap 12, 13, 14

if youre looking at this, sry i lost motivation

shit said in lecture:

epidermis: squamous epithelium, we shed a lot of these cells, does not hurt to stab, not vascularized

dermis: where you can see follicles of hair

sub tissue: cushioning and shock absorption, certain meds get absorbed into this layer

connective tissue there are macrophages that help with the inflammatory response

opportunistic: when there is a cut there is an opportunity to get an infection, ulcer, or any opening

vascular birthmarks look like stork bites or angel kisses, they fade

Mongolia spot, blue fades too

port whine birthmark, grows with you

keratin: durability and stability

melanin: determines color

red appearance, melanin not there to trap the light in the retina, albinism more likely to have visual disturbances

vitiligo: cells attacking the melanin

translucent skin, age dark spots, very frail and thin skin with aging; can bruise easy, tear easy, epidermis atrophy

ages: more likely to have progressive ulcers and difficulty healing'

complications: risks for injuries and they may not realize it

contact derm: type 4 hypersensitivity, position ivy, macrophages release the histamine and inflammatory response in the derm

atopic derm (eczema): chronic inflammatory, mostly in kids, stress or sick cause flare ups, red itchy

urticaria (hives): allergic reaction, stress hives, moisture hives,

psoriasis: s for scaly, skin cells don’t slough off

bacterial infect: localized to one follicle, base gets infected (strap and strep)

boils is folliculitis that has progressed

impetigo: crust and highly contagious to remember

cellulitis: hot asf to touch

fascia (all the way down to the muscles)

shingles is typically older ppl

once crusted over don’t put anything moist bc it could reopen the vesicles

if they have had the chicken pox vaccines u should still get the shingle vaccine

third degree burn don’t blanch, 2nd degree is boiling water or hot wax

need to know the total body surface area affected to know how much fluid to give and what caused the burn

unbroken u can put aloe

two large bore IVs (18 gauge) for two access points for major burns

shock symptoms: low bp, high heart rate, rly anxious, confusion (bc of poor perfusion)

4/11

blasts is building

clasts is dissolve old and damaged

4/16

osteoarthiritis; goals managing the pain and stiffness

osteoblast aren’t working as well with age, obesity, older age

high impact activities, more mechanical stress

herdon highest point on the finger, bacard is close to to the body

soft or boggy; more capillary permeability (RA)

uric acid causes deposits in joints once crystalized (high in blood low in urine)

colochine is an acute attack

18 pressure points and need 11 to be diagnosed

4/18

glaucoma; diabetes

remember acute closed-angle glaucoma!!

trendelenburg is bad (nursing concepts slide)

frog picture (gradual change)

A.double vision (late sign of cataracts)

ear fullness sodium limit

4/23

lots of cones and rods in the macula, very important for light/fine details

females: more likely to have inflammation, can damage small vessels in the eye

hypertension: vessels constricted and tight

atrophying bc of decreased perfusion, and dry: older age related, gradual. wet: drainage where shit shouldnt be and any age, sudden

no pain with retinal detachment

meniere’s; hearing, vertigo, tinnitus

drown out tinnitus with background noise/white noise

central vertigo= central nervous system.. vertigo lasts 20 min to a few hours.. nothing longer than 12 or it might be something else
