PTAP 2230 Exam 1 || correct answers 100%.
What is the outermost layer of the skin? What is its function? correct answers Epidermis -
Contains melanocytes, Protects the skin from water loss, physical damage and sensation.
What is the dermis? What is its function? correct answers Layer below the epidermis and is
composed of collagen and elastin fibers.
Supplies nutrients and oxygen to the skin through the capillary bed, supports skin structure and
strength.
What structures are in the dermis? correct answers - Blood and lymphatic vessels
- Nerve endings
- Hair follicles
- Sebaceous and sweat glands
- Fibroblasts
What is the hypodermis? What does it contain? correct answers - Composed of adipose and
connective tissue
- Contains major blood and lymph vessels and nerves
What is the physiology of the skin? correct answers - Protection from infection and water loss
- Excretion of water and waste (urea and uric acid)
- Sensory perception through nerve endings and identify and avoid danger
- Thermoregulation vasodilation increasing sweat production when temp is increased and
vasoconstriction when exposed to cold or decreased body temp
- Metabolism and synthesizes vitamin D and maintains mineralization of bones and teeth
- Absorption of some drugs directly into the bloodstream
, What are the phases of healing? correct answers Phase 1: inflammation days 1-10
Phase 2: Proliferation days 3-21
Phase 3: Remodeling/maturation 7 days - 2 years
What happens in phase 1 of healing? correct answers Inflammation occurs, neutrophils destroy
bacteria, initially blood vessels constrict do minimize blood loss, vasodilation occurs after to
facilitate healing by increasing blood flow.
What happens in phase 2 of healing? correct answers Angiogenesis (formation of new blood
vessels), fibroblasts secrete collagen and new tissue fills wounds.
What happens in phase 3 of healing? correct answers Decrease capillaries and scar tissue
contracts/matures.
What are PT interventions for phase 1 and 2 of healing? correct answers - Promote healing
- Promote blood flow and tissue oxygenation
What are PT interventions for phase 3 of healing? correct answers - Do not disrupt repair process
- Promote blood flow and tissue oxygenation
- Promote scar tissue remodeling
Where does epithelialization happen first? correct answers First happens in the epidermis
Granulation tissue is usually located in what part of the wound? correct answers Wound bed
What are normal drainages? correct answers Serous: Clear, thin, watery
Sanguineous: Red, thin, watery
Serosanguinous: Red or pink, thin, watery
