Integumentary System Flashcards
Physical assessment approach
Head to toe, anterior, posterior and lateral
Or by region as other systems are assessed
Physical assessment techniques for integumentary system
Inspection and palpation
Inspection of the skin should look at..
Color
Odor
Integrity
Any lesions
Pallor
An unhealthy pale appearance
Erythema
Flushed appearance, redness
Pediculosis
Infection of the hair follicles
Normal base angle of nails =
160 degrees
Atrophic
Thinning
+1 edema
Mild (2mm)
No perceptual swelling
+2 edema
Moderate (4mm)
Indentation subsides quickly
+3 edema
Severe (6mm)
Indentation remains for a short time, leg looks swollen
+4 edema
Pitting (8 mm)
Indentation lasts for a long time
Normal skin elasticity test =
Brisk turgor
Occiput
Back of head
Indurated
Elevated, defined borders (usually red)
Granular
Little tiny bumps
Erythematous
Red
Pedunculation
Skin tags
Exudate
Fluid
Cellulitis
Infection of the skin
Annular
Circular (freckle, mole, ulcer)
Confluent
When things merge together and touch each other
Discrete
Singular and separate from one another
Gyrate
More of a coil or S-like pattern
Grouped
Many lesions in one area (hives, freckles, burns)
Linear
Follows one track (spider bites, burns, incisions)
Target
Looks like a bulls-eye (usually bug bite, sometimes burn)
Zosteriform
Relatively specific to shingles virus, follows neurological tract
Two types of lesions
Primary & secondary
Primary lesion
Initial alteration of the skin
Secondary lesion
Arises from a change in primary lesion
Macule
Solely a color change, flat and circumscribed, less than 1 cm
Examples of macules
Freckles, flat nevi, petechiae
Petechiae
Pinpoint, round spots that appear on the skin as a result of bleeding
Nevi
Birthmark or mole
Patch
Macules that are larger than 1 cm
Examples of patches
Mongolian spot, vitiligo, cafe au lait spot
Papule
Something you can feel (i.e, solid, elevated, circumscribed, less than 1 cm diameter) caused by superficial thickening in the epidermis
Examples of papules
Elevated nevus, wart (nevus)
Plaque
Papules coalesce to form surface elevation wider than 1 cm
Polycyclic
Many of them in one small area
Examples of plaque
Psoriasis
Melanoma assessment
Asymetry
Border
Color
Diameter
Nodule characteristics
Elevated Firm Circumscribed lesion Deeper in dermis than papule >0.5cm in diameter
Tumor
Elevated and solid lesion that may or may not be clearly demarcated deeper in the dermis
Greater than 2 cm in diameter
Wheal
Superficial, raised, transient and erythematous, slightly irregular shape due to edema (fluid held diffusely in the tissues)
Wheal examples
Mosquito bite, allergic reaction, dermographism
Dermographism
Where skin is under reaction, usually from drug
Urticaria is AKA
hives
Urticaria
Wheals coalesce to form extensive reaction, usually pruritic
Vesicle
Elevated cavity containing free fluid, up to 1 cm; a “blister”
Clear serum flows if wall is ruptured
Examples of vesicles
Herpes simplex, early varicella (chickenpox), herpes zoster (shingles)
Bulla
Larger than 1 cm diameter; usually single chambered (unilocular); superficial in epidermis; thin walled-ruptures easily
Examples of bulla
Friction blister, burns, contact dermatitis
Pustule
Elevated, superficial lesion similar to vesicle but filled with purulent fluid
Circumscribed and elevated
Pustule examples
Impetigo, acne
Cyst
Elevated, circumscribed, encapsulated lesion in dermis or subcutaneous layer
Filled with liquid or semisolid material
