• goal of medical asepsis

Answer decrease number and transfer of pathogens

• examples of medical asepsis

Answer hand hygiene, personal protection equipment (PPE) ex clean gloves, gown, masks, eyeshields

• when to use medical asepsis

Answer at all times

• biggest function of the skin

Answer protection

• why do active people have healthier skin?

Answer people that move around more have better circulation so the skin is being fed with blood and nutrients

• factors affecting skin integrity

Answer 2 / 3

developmental level, circulation, state of health, medical interventions

• developmental level

Answer

• infants ’ skin is thinner, weaker, and more susceptible to infection

• older adults ’ thinner and dry skin, delayed healing time, less elastic (decrease in fibroblast

and collagen production)

• circulation

Answer **adequate circulation is needed for long skin cell life

• mobility/activity level ’ immobility decreased circulation to skin and tissues
• nutrition/hydration ’ decreased circulation leads to inadequate cell nutrition

• state of health

Answer

• physical status ’ being too thin or obese

• reduced sensation ’ temperature, pressure, friction
• dehydration/malnutrition ’ adequately nourished & hydrated skin cells are more resistant to

injury

• diseases ’ can cause decreased sensation or increased risk of skin complications
• mental status ’ may affect sensation, ability to understand instructions
• skin moisture ’ diaphoresis, incontinence

• medical interventions

Answer

• diagnostic tests ’ GI prep

• therapeutic tx ’ bed rest, casts, medications

• what are the 4 phases of wound healing?

Answer hemostasis, inflammatory phase, proliferation phase, maturation phase
