COMPREHENSIVE QUESTIONS AND ANSWERS
SURE A+
✔✔Disinfection - ✔✔Chemical disinfectant that destroys most but not all organisms
(must be in for 10 minutes)
✔✔Bactericidal - ✔✔Kills bacteria
✔✔Virucidal - ✔✔Kills viruses
✔✔Fungicidal - ✔✔Kills fungi
✔✔Sterilization - ✔✔Destroys all pathogens and microbial life, ex. Autoclaves: using
high pressure steam under dry heat
✔✔Single Use - ✔✔Disposables items that cannot be used more than once
✔✔Multi-use - ✔✔Reusable items that can be cleaned and disinfected even if exposed
to blood or bodily fluids
, ✔✔Cross-contamination - ✔✔Touching an object without cleaning hands and then
touching another object
✔✔Aseptic Procedures - ✔✔Process of properly handling sterilized and disinfected
equipment and supplies
✔✔Skin Histology - ✔✔Study of the structure and composition of the skin tissue
✔✔Skin Physiology - ✔✔Study of the functions of living organisms
✔✔Second Degree - ✔✔Affects the top two layers of the skin.
✔✔Asymptomatic - ✔✔Showing no symptoms or signs of infection
✔✔Porous - ✔✔Made or constructed of a material that has openings
✔✔Nonporus - ✔✔Has no pores or openings and cannot absorb liquid
✔✔Mycrobacterium Fortuitum - ✔✔Microscopic germ that normally exists in tap water
✔✔Skin Histology - ✔✔Study of the structure and composition of the skin tissue
✔✔Skin Physiology - ✔✔Study of the functions of living organisms
✔✔6 Skin Functions - ✔✔Protection, Absorption, Secretion, Excretion, Temperature
Regulation, Sensation
✔✔Protection - ✔✔Acid mantle protective barrier made up of sebum, lipids, sweat, and
water. Forms a hydrolipidic film to protect the skin from trying out from exposure to
external factors.
✔✔Sensation - ✔✔Responds to touch, pain, cold, heat and pressure
✔✔Thermoregulation - ✔✔Average internal temp is 98.6° F through evaporation,
perspiration, radiation, and insulation
✔✔Excretion - ✔✔Sudoriferous glands; sweat glands detoxifies the body by excreting
excess water, salt, and unwanted chemicals
✔✔Secretion - ✔✔Sebum; oily substance that protects and lubricates the skin.
Sebaceous glands; oil glands. Skin is 50 to 70% water and slows down the evaporation
of water Transepidermal Water Loss (TEWL)
✔✔Absorption - ✔✔Absorbs water, ingredients, oxygen necessary for skin's health.
