Integumentary System (Exam 3) Flashcards
Two layers of skin
Epidermis: Exposed to the outside (Basal push olde cells to surface)
Dermis: Inner layer (strength support protecting) (Sweat glands nerves)
Primary Purpose of Skin
-Protection
-Sensory Perception
Pitting Edema
Know the scale
Pallor
-Loss of color, in black skin tones can change to grey
-Look in mucous membranes
Pallor: Indications
-Anemia, shock, lack of blood flow.
Cyanosis
Bluish discoloration, in brown skin tones can turn yellow-brown-grey
Nails bed, lips, mucousa
Cyanosis: Indications
Hypoxia or impaired venous return (blue feet)
Jaundice:
Yellow discoloration
Sclera, skin, mucous membranes
Jaundice: Indication
Liver dysfunction (RBC destruction)
Palms of hands best way. Sometimes eyes can have a little tent to them
Erythema:
Redness, difficult to see in darker skin tones, palpate skin as well to look for warmth and texture changes
Face, skin, pressure prone areas
Erythema: Indications
Inflammation, vasodilations, sun exposure, elevated body temp
Shear
-Sliding movement of skin and subcutaneous tissue when muscle and bones are not moving
-Dermal layers that are under epidermis. Can not really see damage
Friciton
-Two surfaces moving across one another
-Outer layer so we can see the damage
Moisture
Duration and amount of moisture determine risk
Patients at Risk for Impaired Skin Integrity
PP slide
Pressure Injuries
-Describes impaired skin integrity related to unrelieved prolonged pressure
Pressure applied over capillary in the skin–> capillary can not deliver blood
Tissue Ischemia
Tissue death from not having enough blood
Three major factors involved in pressure injury development:
- Pressure intensity
- Pressure duration
- Tissue tolerance
-low blood pressure, poor nutrition, aging, hydration status all affect tissue tolerance
