All of the following are false statements about atopic dermatitis except:
A) Contact with cold objects may exacerbate the condition
B) It does not have a linear distribution
C) It is associated with bullae
D) The lesions have vesicles that are full of serous exudate - (ANSWER)B) It does not have a linear
distribution Atopic dermatitis, also known as eczema, is a skin condition in which the lesions occur in a
linear fashion. They may have many different stages, including erythematous papules and vesicles, with
weeping, drainage, and/or crusting. Lesions are commonly pruritic and are found on the scalp, face,
forearms, wrists, elbows, and backs of the knees.
Koplik's spots are associated with:
A) Poxvirus infections B) RubeolaC) Kawasaki's disease D) Rubella - (ANSWER)B) Rubeola Rubeola is the
Latin name for measles. Signs and symptoms of measles infection include fever over 101°F, coryza,
cough, conjunctivitis, rash, and Koplik's spots on the buccal mucosa. Do not confuse rubeola with rubella
(German measles or 3-day measles).
Your female patient of 10 years is concerned about her most recent diagnosis. She was told by her
dermatologist that she has an advanced case of actinic keratosis. Which of the following is the best
explanation for this patient?
A) It is a benign condition
B) It is a precancerous lesion and needs to be followed up with her dermatologist
C) It will diminish with application of hydrocortisone cream 1% BID for 2 weeks
D) It is important for her to follow up with an oncologist - (ANSWER)B) It is a precancerous lesion and
needs to be followed up with her dermatologist Actinic keratoses are small, raised skin lesions that result
from extended sun exposure. Some actinic keratoses may develop into skin cancer; therefore, further
evaluation is needed to determine if removal is required.
What does a potassium hydroxide (KOH) prep help the nurse practitioner 531 diagnose?

D) Viral infections - (ANSWER)B) Fungal infections The potassium hydroxide (KOH) prep test is performed
650 to evaluate for tinea or candida (yeast) infection of the skin. In vaginal discharge, the yeast organism
is outside the skin cells, so KOH is not needed to visualize it. But for skin cells, yeast is not visible unless
the skin cell walls are destroyed by KOH. The test involves placing a sample of skin on a glass slide, with
one to two drops of KOH (causes lysis of skin cells) and a coverslip on top. If done correctly, you can
visualize the budding spores and pseudohyphae.
The following skin findings are considered macules except:
A) A freckleB) PetechiaeC) AcneD) A flat, 0.5-cm brown birthmark - (ANSWER)C) Acne A macule is a flat,
nonraised lesion on the skin. Acne lesions are papules because they consist of raised, erythemic lesions
on the skin. A freckle, petechiae, and a flat birthmark are all considered macules.
A new patient is complaining of severe pruritus that is worse at night. Several 540 family members also
have the same symptoms. Upon examination, areas of excoriated papules are noted on some of the
interdigital webs of both hands and on the axillae. This finding is most consistent with:
A) Contact dermatitis B) ImpetigoC) Larva migransD) Scabies - (ANSWER)D) Scabies Scabies is a parasitic
disease (infestation) of the skin caused by the human itch mite Sarcoptes scabiei. The rash is generally
characterized as red, raised excoriated papules. The scabies mite is generally transmitted from one
person to another by direct contact with the skin of the infested person and can also be acquired by
wearing an infested person's clothing (fomites), such as sweaters, coats, or scarves. Following the
incubation period, the infested person will complain of pruritus (itching), which intensifies at bedtime
under the warmth of the blankets. Common sites of infection are the webs of fingers, wrists, flexors of
the arms, the axillae, lower abdomen, genitalia, buttocks, and feet.
A bulla is defined as:
A) A solid nodule less than 1 cm in size
B) A superficial vesicle filled with serous fluid greater than 1 cm in size
C) A maculopapular lesion
D) A shallow ulcer - (ANSWER)B) A superficial vesicle filled with serous fluid greater than 1 cm in size This
isa blister—a circumscribed, fluid-containing, elevated lesion of the skin, usually more than 5 mm in
diameter.

Which of the following conditions is associated with a positive Auspitz sign?
A) Contact dermatitis
B) Seborrheic dermatitis
C) Systemic lupus erythematosus
D) Psoriasis - (ANSWER)D) Psoriasis The Auspitz sign is simply bleeding that occurs after psoriasis 665
scales have been removed. It occurs because the capillaries run very close to the surface of the skin
under a psoriasis lesion, and removing the scale essentially pulls the tops off the capillaries, causing
bleeding. Auspitz sign is also found in other scaling disorders such as actinic keratoses.
A first-grader presents to a school nurse practitioner with a few blisters on one 549 arm and on his face.
The child keeps scratching the affected areas. Some of the lesions have ruptured with yellow serous fluid
that crusts easily. These findings best describe:
A) Acute cellulitis
B) Herpes zoster
C) Bullous impetigo
D) Erysipelas - (ANSWER)C) Bullous impetigo Bullous impetigo is an infection of the skin caused by
Staphylococcus aureus, which produces exfoliative toxin A. The infection is more common in young
children. It is characterized by flaccid large blisters filled with serous fluid. When the bullae rupture, the
serous fluid dries up and resembles honey- colored crusts. If the child has a limited number of skin
lesions, topical therapy with mupirocin (Bactroban) is effective. But if lesions are extensive, systemic
antibiotics, such as Dicloxacillin and cephalexin, are the treatment of choice.
The mother of an 8-year-old boy reports the presence of a round red rash on the child's left lower leg. It
appeared 1 week after the child returned from visiting his grandparents, who live in Massachusetts.
During the skin exam, the maculopapular rash is noted to have areas of central clearing making it
resemble a round target. Which of the following is best described?
A) Erythema migrans
B) Rocky Mountain spotted fever
C) Meningococcemia D) Larva migrans - (ANSWER)A) Erythema migrans Erythema migrans is a symptom
of early Lyme disease. It is an annular lesion that slowly enlarges with time (days to weeks) and has
central clearing. It is caused by a bite from an infected (Borrelia burgdorferi) blacklegged tick. If
untreated, infection will spread to joints, nervous system, and heart. Most cases of Lyme disease occur in
the Northeast, mid-Atlantic states, Wisconsin, Minnesota, and northern California.
