Midterm Review Flashcards
4 basic techniques of assessment
inspection
auscultation
percussion
palpation
doppler
used to asses pulses when pulses cannot be palpated
stadiometer
used to measure height
wood lamp
used to assess fungal infections on the skin
goniometer
used to measure degree of joint flexion and extension
transilluminator
use to detect air, blood, fluid, or mass in body cavity
epidermis
top layer of skin
dermis
contains nerves, blood, and lymphatic vessels
- embedded with hair follicules, sweat glands, oil glands, and sensory nerves
subcutaneous tissue
third layer of skin
stage 1 pressure injury
1 layer of skin is affected
- intact, but red and non-blanchable
stage 2 pressure injury
2 layers affected (epidermis and dermis)
- bleeding
stage 3 pressure injury
3 layers affected (epidermis, dermis, and subcutaneous)
- see subcutaneous tissue
- skin is completely compromised
stage 4 pressure injury
can see muscles and bones
grading of skin edema
press around bony prominences w/ 3 finger pads
- 0: no edema
- 1+: 2mm
- 2+: 4mm
- 3+: 6mm
- 4+: 8mm
annular vs target lesion
configuration/shape
both circular lesions
- annular: only 1 circle
- target: circle with concentric circles inside w/ dot at center (bullseye lesion)
wheal
primary lesion
reddened, irregular borders, elevated
- cause by insect bite or hives
macule
primary lesion
flat, circumcised border, change in skin color, <1cm
ie/ freckles, petichiae
patch
primary lesion
irregular, >1cm
ie/ mangolian spots, port wine stain, vitiligo
type of macule
vesicle vs bulla
primary lesion
fluid filled round, oval w/ translucent wall
- vesicle: <0.5cm
*ie/ chicken pox, poison ivy, small burn blister
- bulla: >0.5cm
ie/ large burn blisters
port wine stain
vascular lesion
on face that is flat, deep purple/red, irregular shaped
- deepens when person cries or is highly emotional or high temperature
- typically does not fade
spider angioma
vascular lesion
flat, bright red dot w/ tiny radiating blood vessels ranging from pinpoint to 2cm
venous lake
vascular lesion
on the face, neck, ear, and lips; usually common in ages 50+
- soft, compressible, slightly elevated dark blue to purple
- may be due to sun exposure
senile lentigines (liver spots)
usually on hands like hyperpigmented freckles
- common in elderly
cutaneous tags
usually on the neck and upper chest
- common in elderly
- may increase in numbers
manifestations of cirrhosis of the liver
- skin variation: yellowish (jaundice) due to not getting rid of billirubin
tinea pedis
also known as athletes foot
keloid
secondary lesion
elevated, irregular, darkened; excess scar tissue
- the primary lesion: scar
ABCDE criteria
used to rule out malignant lesions
- A: asymmetry
- B: border irregularity
- C: color (varied)
- D: diameter >6mm
- E: evolving change
malignant melanoma
most serious type of skin cancer b/c it spreads rapidly to lymph and blood vessels
- varied colors, irregular borders, >6mm
kaposi’s sarcoma
malignant lesion
painless; blue to purple; resembles keloid; common in HIV patients
black hairy tongue
consistent w/ fungal infection of the tongue
leukoplakia
whitish thickening of the mouth of HIV positive patients
- cannot be scraped off
risk factors of skin cancer
predisposition
- overexposure to UV light
- genetic predisposition
order of occurence of herpes zoster
1) parasthesia (burning/tingling sensation)
2) redness and swelling
3) development of vesicles/blisters
4) weaping blisters
5) crusted lesions
6) posthepaticneuralgia (pain/burning sensation long after blisters disappear
cause of shingles (herpes zoster)
chicken pox virus
lanugo
normal variation
fine, downy hair in newborns
- prominent in the upper chest, shoulder, and back
mongolian spots
normal variation
harmless purplish/blue spots on the sacral area
- common in dark skin
- disappears at age 3
vernix caseosa
normal variation
harmless white, cheese-like mixture of sebum and epidermal cells on skin of newborn
- disappears after several bathings
milia
normal variation
pimple like whiteheads on the nose or cheeks of the newborn
- disappears after 2-3 weeks
vitiligo
harmless white, patchy depigmented areas over the face, neck, hands, and skinfolds of newborn
- does not disappear
hydrocephalus
enlarged head w/ prominent, visible scalp veins
- due to accumulation of cerebral spinal fluid in the head of the baby
craniosynostosis
premature closure of the coronal and saggital sutures of the head
- elongated head and altered orbital and face of baby
vellus hair
short, fine, pale all over the body except lips, nipples, palms, and soles of feet
terminal hair
longer and coarser hair
- on eyebrows, scalp, axillary, leg, pubic, and face/chest of men
stages of hair growth
- anagen: growth phase; 2-6 yrs
- catagen: transitional phase; 2 weeks
- telogen: shedding phase; 1-4 months
eccrine gland
sweat gland
made of water and salt
- located all over the body
apocrine gland
sweat gland
made of water, salt, protein, fatty acids
- in groin and axillary region
- when mixed with bacteria = musty
sebaceous glands
predominant in scalp area
palpating lymph nodes
gentle, circular motion
assessing for hearing loss
important to ask if there is family history of hearing loss
normal tympanic membrane
pearly gray
white patches on tympanic membrane
indicates previous ear infection
