module 3: skn, hair, nails Flashcards
when inspecting and palpating the hair, look for
- color
- texture
- ditribution
- lesions
when inspecting and palpating the nails, look for:
- shape & contour (slightly curved/flat) → The profile sign (view of index finger at its profile and note angle of nail base) ~160 degrees
- consistency: smooth and regular, not brittle or splitting
-color: translucent to pink nail bed - Capillary refill: healthy color return takes 1-2 sec.
degree of normal, curved, and early clubbing nails.
normal: 160 degrees
curved nail: 160 degrees or less
ealy clubbing: flat 180 degrees
clubbing of nails occurs with:
congenital cyanotic heart disease, lung cancer, and pulmonary diseases
widespread color change of the skin
Pallor, erythema, cyanosis, jaundice
Pallor
(PALE) loss of color; red-pink tones from oxygenated
hemoglobin in the blood are lost
Erythema
intense redness of skin(infection/fever); due to excess blood in dilated superficial capillaries
cyanosis
bluish mottled color; signifies decreased perfusion
of oxygenated blood to the tissues
jaundice
yellowish skin color; indicates rising amounts of bilirubin in blood.
First place you’ll see? Soft and hard palate of mouth.
Danger signs or abnormal characteristics of pigmentd lesions: ABCDEF (ABNORMAL)
A - asymmery
B - border
C - color
D - diameter (measure in mm)
E - elevation and enlargement
F - funny looking
When inspecting and palpating the skin
-temp (palpate using back of both hands)/should be wam and equal bilaterally.
-moisture (dehydrated? Look in mouth)
- texture (smooth, even, firm)
- thickness
- edema
- mobility (ease of rise) or turgor (ability of skin to return/snap back to place
- vascularity or bruising
- lesions
Edema:
-pitting vs non pitting (on tibia bone/both side @ same time)
If edema is pitting, grade on scale
- 1+ Mild pitting
- 2+ Moderate pitting
- 3+ Deep pitting (short time indentation)
- 4+ Very deep pitting (long term indentation)
What are lesions?
Primary vs secondary
Traumatic/pathological changes, abnormal development
Primary: something you wake up with
Secondary: changed over time
If any lesions are present note:
- Color
- Elevation: flat/raised skin tag
- Pattern or shape
- Size: lesion in cm / mole in mm
- Location and distribution on body
- Any exudate: note color and odor
Common shapes/ configurations of lesions: refer to p228
ANNULAR
(Or circular) begins in center & spreads to periphery (outer limits or edge)
Ex: tinea corporis or ringworm, tinea versicolor, pityriasis rosea)
Common shapes/ configurations of lesions: refer to p228
CONFLUENT
Lesions run together/ touching
Ex: urticaria (hives)
Common shapes/ configurations of lesions: refer to p228
DISCRETE
Distinct, individual lesions that remain separate (ex: acrochordon or skin tags, acne)
Common shapes/ configurations of lesions: refer to p229
GROUPED
Cluster of lesions (ex: vesicles of contact dermatitis)
Common shapes/ configurations of lesions: refer to p229
LINEAR
A scratch, streak, line, or stripe.
