RATIONALES
1. Which layer of the skin is primarily targeted by
medical aesthetic procedures such as chemical
peels and laser resurfacing?
A) Epidermis
B) Dermis
C) Subcutaneous tissue
D) Stratum corneum
Correct answer: B
Rationale: The dermis is the middle layer containing
collagen, elastin, and blood vessels; it is the primary
target for many medical aesthetic procedures aimed
at skin rejuvenation.
2. What is the primary role of melanocytes in the
skin?
A) To produce collagen
B) To produce melanin
C) To produce sebum
,D) To produce keratin
Correct answer: B
Rationale: Melanocytes are cells in the basal layer of
the epidermis that produce melanin, the pigment
responsible for skin and hair color.
3. The outermost layer of the epidermis, composed of
dead keratinized cells, is called the:
A) Stratum basale
B) Stratum spinosum
C) Stratum granulosum
D) Stratum corneum
Correct answer: D
Rationale: The stratum corneum is the outermost
layer of the epidermis, consisting of dead, flattened
keratinocytes that provide a protective barrier.
4. Which of the following is a function of the skin?
A) Protection against pathogens
B) Temperature regulation
C) Sensory perception
D) All of the above
,Correct answer: D
Rationale: The skin serves multiple functions
including protection from trauma and pathogens,
temperature control, and sensory appreciation.
5. What is the primary structural protein found in the
dermis that provides strength and support?
A) Elastin
B) Collagen
C) Keratin
D) Melanin
Correct answer: B
Rationale: Collagen is the most abundant protein in
the dermis, providing structural support and strength
to the skin.
6. Which condition is characterized by white patches
of skin due to loss of melanocytes?
A) Melasma
B) Vitiligo
C) Albinism
D) Hyperpigmentation
Correct answer: B
, Rationale: Vitiligo is an autoimmune condition where
melanocytes are destroyed, resulting in depigmented
white patches on the skin.
7. What is the most common cause of post-
inflammatory hyperpigmentation (PIH) in medical
aesthetic treatments?
A) Allergic reaction
B) Inflammation or injury to the skin
C) Bacterial infection
D) Viral infection
Correct answer: B
Rationale: Post-inflammatory hyperpigmentation
(PIH) is a darkening of the skin that occurs following
inflammation or injury, such as after chemical peels
or laser treatments.
8. Which of the following is an absolute
contraindication for most medical aesthetic
procedures?
A) Mild acne
B) Active herpes simplex (cold sore) in the treatment
area
C) Dry skin
