NKU MSN 610 MODULE 2 EXAMS WITH
QUESTIONS AND ANSWERS.
Macule - correct answer-A flat circumscribed area that is a
change in the color of the skin, < 1 cm in diameter.
Examples - freckles, flat moles (nevi), petechiae, measles.
Papule - correct answer-An elevated, firm, circumscribed area,
< 1 cm in diameter.
Examples- wart (verruca), elevated moles, lichen planus.
Patch - correct answer-A flat nonpalpable, irregularly shaped
macule > 1 cm in diameter.
Examples: Vitiligo, port wine stains, hyperpigmented macule,
café au lait patch.
plaque - correct answer-Elevated, firm, and rough lesion with
flat top surface > 1 cm in diameter.
Example- Psoriasis, seborrheic, and actinic keratosis.
Wheal - correct answer-Elevated, irregular shaped area of
cutaneous edema solid transient variable diameter.
Example: insect bites urticaria allergic reaction.
Nodule - correct answer-Elevated firm circumscribed lesion
deeper in dermis than papule 1-2 cm in diameter.
Example- Erythema nodosum , lipoma.
,Mass - correct answer-Elevated and solid lesion, may or may
not be clearly demarcated, deeper in dermis > 2 cm in diameter.
Example: Neoplasms, benign tumor, lipoma.
Vesicle - correct answer-Elevated circumscribed, superficial, not
into dermis, filled with serous fluid, < 1 cm in diameter.
Example- Varicella, herpes zoster.
Bulla - correct answer-Vesical > 1 cm in diameter
Example- Blister, pemphigus vulgaris.
pustule - correct answer-Elevated superficial lesion, similar to
vesicle but filled with purulent fluid.
Example- Impetigo, acne.
Cyst - correct answer-Elevated, Circumscribed, encapsulated
lesion, in dermis or subcutaneous layer, filled with liquid or
semisolid material.
Example- Sebaceous cyst, cystic acne.
Telangietasia - correct answer-Fine, irregular, red lines
produced by capillary dilation.
Example- Telangiectasia in rosacea.
Scale - correct answer-Heaped up keratinized cells, flaky skin
irregular, thick or thin dry or oily variation in size.
Example- Flaking of skin with seborrheic dermatitis or after a
dog reaction dry skin.
, Lichenification - correct answer-Rough thickened epidermis
secondary to persistent rubbing, itching, or skin irritation, often
involves flex surface of extremity.
Example- Chronic dermatitis.
Keloid - correct answer-Irregularly shaped elevated
progressively enlarging scar, grows beyond the boundaries of
the wound caused by excessive collagen formation during
healing.
Example- keloid formation after surgery.
Scar - correct answer-Thin to thick fibrous tissue that replaces
normal skin after injury or laceration to the dermis.
Example- Healed wound or surgical incision.
Excoriation - correct answer-Loss of the epidermis linear
hollowed out crusted area.
Example- Abrasion or scratch scabies.
Fissure - correct answer-Linear crack or break from the
epidermis to the dermis may be moist or dry.
Example- Athlete's foot, cracks at the corner of the mouth.
Erosion - correct answer-Loss of part of the epidermis,
depressed, moist, glistening, follows rupture of a vesicle or
bulla.
Example- Varicella, variola after rupture.
