What is the most common malignant bone tumor diagnosed during childhood?
a. Chondrosarcoma
b. Fibrosarcoma
c. Ewing Sarcoma
d. Osteosarcoma - answer-d. Osteosarcoma
Exp: Of the options available, osteosarcoma is the most common bone tumor that occurs during
childhood; it originates from bone-producing mesenchymal cells. page 1610
Molecular analysis has demonstrated that osteosarcoma is associated with which gene? a.
TP53
b. src
c. myc
d. TSC2 - answer-b. src
Exp: page 1610
Oteosarcoma usually metastasizes to the:
a. Pancreas
b. Liver
c. Lungs
d. Brain - answer-c. Lungs
Exp: Osteosarcoma disseminates through the bloodstream, usually to the lung. As many as 25% of
children diagnosed with osteosarcoma exhibit lung metastases at diagnosis. This statement is not true of
any of the other options. page 1610
In latex allergies, which immunoglobulin (Ig) is associated with an immediate reaction?
a. IgA
,dmuwodmfdmuwodmfdmuwodmf-07b95b3f91e23ae54ec32dabf3fdcf3f
b. IgE
c. IgG
d. IgM - answer-b. IgE
Exp: Latex allergy can be either a type IV hypersensitivity to chemicals used in latex rubber processing or
a type I immediate hypersensitivity with IgE antibodies formed in response to latex rubber protein. This
selection is the only correct option available page 1628
What medical term is used to identify an inflammatory disorder of the skin that is often considered
synonymous with dermatitis and characterized by pruritus with lesions that have an indistinct border? a.
Eczema
b. Psoriasis
c. Atopic dermatitis
d. Pityriasis rosea - answer-a. Eczema
Exp: The most common inflammatory disorder of the skin is eczema, or dermatitis. Eczema and
dermatitis are general terms that describe a particular type of inflammatory response in the skin-these
terms can be used interchangeably. Pruritus, lesions with indistinct borders, and epidermal changes
generally characterize diseases that are considered eczematous. Of the available options, only eczema is
associated with these characteristics. page 1627
Lesions on the elbows and knees that are well demarcated, thick, silvery, scaly, and erythematous
characterize which type of psoriasis?
a. Plaque
b. Inverse
c. Guttate
d. Erythrodermic - answer-a. Plaque
Exp: The description provided is characteristic of only lesions observed in plaque psoriasis. These lesions
are well-demarcated, thick, silvery, scaly, erythematous plaque surrounded by normal skin. page 1629
Chickenpox (varicella) may be followed years later by which disorder? a.
Erysipelas
b. Cytomegalovirus
c. Warts (Verrucae)
,dmuwodmfdmuwodmfdmuwodmf-07b95b3f91e23ae54ec32dabf3fdcf3f
d. Herpes Zoster - answer-d. Herpes Zoster
Exp: The same herpesvirus
- varicella zoster virus -causes both herpes zoster (shingles) and varicella (chickenpox). Varicella is the
primary infection, followed years later by herpes zoster, particularly among those who are
immunosuppressed. These statements are not true of any of the other options. page 1636
Which skin lesion is mediated by the immunoglobulin E IgE- stimulated release of histamine, bradykinin,
or kallikrein from mast cells?
a. Dermatitis
b. Scleroderma
c. Urticaria
d. Cutaneous vasculitis - answer-c. Urticaria
Exp: Only urticaria is mediated by the IgE - stimulated release of histamine, bradykinin, or kallikrein from
mast cells or basophils, or both which causes the endothelial cells of skin blood vessels to contract. page
1639
What name is given to a benign proliferation of basal cells that produces smooth or warty elevated
lesions on the chest, back, and face that are tan or waxy, yellow flesh-colored, or dark brown to black? a.
Basal keratosis
b. Seborrheic keratosis
c. Keratoacanthoma
d. Actinic keratosis - answer-b. Seborrheic keratosis
Exp: Seborrheic keratosis is a benign proliferation of cutaneous basal cells that produces smooth or
warty elevated lesions. The pathogenetic origin is unknown. Seborrheic keratosis usually occurs in older
people as multiple lesions on the chest, back, and face. The color varies from tan to waxy, yellow
fleshcolored, or dark brown to black. No other option exhibits these characteristics. page 1640
What is the medical term for a fungal infection of the nail plate?
a. Paronychia
b. Onychomycosis
c. Tinea corporis
, dmuwodmfdmuwodmfdmuwodmf-07b95b3f91e23ae54ec32dabf3fdcf3f
d. Tinea capitis - answer-b. Onychomycosis
Exp: Onychomycosis is the only term used to identify a fungal or dermatophyte infection of the nail plate
that occurs in 2 to 18% of the population. page 1647
Which medications may exacerbate existing psoriasis?
(Select all that apply.) a
Antibiotics
b. Calcium channel blockers
c. Nonsteroidal anti-inflammatory drugs NSAIDS
d. Beta blockers
e. Lithium - answer-c. Nonsteroidal anti-inflammatory drugs NSAIDS
d. Beta blockers
e. Lithium
Exp: Antimalarial drugs, lithium, NSAIDs , and beta-blockers tend to exacerbate existing psoriasis. This
statement is not true of the remaining options. page 1629
The disruption in cellular adhesion observed in bullous impetigo is caused by an exfoliative toxin related
to which organism?
a. Staphylococcus aureus
b. Streptococcus pyogenes
c. Escherichia coli
d. Candida albicans - answer-a. Staphylococcus aureus
Exp: Bullous impetigo is a rare variant of impetigo caused by S. aureus. The staphylococci produce a
bacterial toxin called exfoliative toxin
(ET), which causes a disruption in desmosomal adhesion molecules with blister formation characteristic
of bullous impetigo. This selection is the only option that identifies the correct organism. page 1654
The staff member of a crowed day care center is a source for which bacterial infection? a.
Atopic dermatitis
b. Staphylococcal scalded-skin syndrome
