Which of the following statements accurately describes how the skin functions as a
barrier between the internal and external environments? (2)
A. The skin lipids bind water, normally maintaining skin water content at 20% or higher
B. When the barrier function of the skin is compromised, transepidermal water loss
(TEWL) decreases

changes that occur in aging skin. What is one of these changes? (2)
A. Increase in melanocytes
B. Rounding of dermal-epidermal junction
C. Increase in Mast Cells

greatest. percutaneous absorption? (2)
A. Plantar surface of the foot
B. Forearm

B. Do not use products no the skin that have known sensitizers
C. Bathe frequently using water that is as hot as tolerated

Which layer of skin contains cells that release lipids such as ceramides to maintain the
normal "brick and mortar" skin barrier function. (2)
A. Stratum germinativum
B. Stratum basale
C. Stratum spinosum
D. Stratum granulosum - ANSWER-D
Daily bathing is not usually necessary for which patient populations? (L1)
A. Neonates and elderly
B. All age groups should bathe daily
C. Middle aged adults on steroids
D. Toddlers and young adults - ANSWER-A
Which structure of the skin provides the body with photoprotective properties by
absorbing harmful UV light? (2)
A. Melanin
B. Langerhans cells
C. Odland bodies
D. Stratum lucidum - ANSWER-A
What is a unique function of the layer of the epidermis known as the stratum basale? (2)
A. Providing immunity via Langerhans Cells
B. Producing new epithelial cells
C. Releasing lipids to hep maintain normal brick and mortar skin configuration
D. Protecting the palms of the hands and soles of the feet - ANSWER-B - reproductive
layer of the dermis characterized by proliferating keratinocytes
Alkaline products should generally be avoided because they remove protective oils from
the skin and alter the protective "acid mantle." (L1)
