Questions, Answers, and Explanations
Question 1
1. Which of the following organism are responsible for causing the disease pictured below in the
photograph?
A.
B.
C.
D.
Coxsackie Virus
Parvovirus
Herpes Zoster
Epstein Barr Virus
Answer 1
1. Choice B is the correct answer. This child has Fifth's
Disease or Erythema Infectiosum. This caused by the
Parvovirus. It is characterized by a slapped cheek
appearance. It often has a prodrome of fever, coryza,
malaise, headache and sore throat. Coxsackie is the virus
that causes hand foot and mouth disease. Herpes zoster is
the virus that causes chicken pox.
Question 2
2. Which of the following is the best treatment for the condition listed below in the photograph?
A.
B.
C.
D.
Griseofulvin
Nizoral Shampoo
Nystatin
Lamisil
Answer 2
2. Choice A is the correct answer. Tinea
Capitis is treated most effectively orally. Topical
preparations such as nizoral shampoo or
nystatin are not effective. Lamisil is used for
onychomycosis.
Question 3
3. Your patient is a 34 year old female that presents with first and
second degree burns to her entire head and neck, entire right arm and
her anterior torso. She weighs 110 kilograms. What should be the
patient's IV fluid rate for the first 8 hours?
A.
B.
C.
D.
990 mL/hr
660 mL/hr
495 mL/hr
No IV Fluids are necessary
Answer 3
3. Choice A is the correct answer. The patient
has 36% TBSA burns. She weighs 110 kg. So
this applied to the Parkland Formula you get 4
x 110 kg x 36 = 15, 840 mL for the first 24
hours. Divide this by 2 and this gives you 7920
mL for the first 8 hours. When you divide
7920/8 you get the correct answer of 990
mL/hr.
Question 4
4. Which of the following skin disorders has
less than 10% of epidermal detachment?
A.
B.
C.
D.
Toxic Epidermal Necrolysis
Steven Johnson Syndrome
Scalded Skin Syndrome
Pityriasis Rosea
Answer 4
4. Choice B is the correct answer. Steven Johnson
Syndrome has less than 10% of epidermal detachment.
Toxic Epidermal Necrolysis has greater than 30% of
epidermal detachment. Pityriasis Rosea does not involve
epidermal detachment. Scalded Skin Syndrome is caused
by certain strains of staphylococcus infections. Toxins are
produced that cause damage to the skin.
Question 5
5. Which of the following skin disorders has an
association with asthma and allergic rhinitis?
A.
B.
C.
D.
Contact Dermatitis
Psoriasis
Erythema Multiforme
Atopic Dermatitis
Answer 5
5. Choice D is the correct answer. Atopic Dermatitis
does have an association with allergic rhinitis and
asthma. It is a Type I Hypersensitivity reaction.
Lesions are typically present over months to years.
Treated with low potency steroid creams and wet
dressings. UVA and UVB can be helpful. Contact
dermatitis, Psoriasis, and Erythema Multiforme do not
have an association with asthma and allergic rhinitis.
Question 6
6. Which of the following are not considered part of the
accepted treatment of acneiform vulgaris?
A.
B.
C.
D.
Cleocin T
Isotretinoin
Birth Control Pills
Cyclosporine
Answer 6
6. Choice D is the correct answer. Acne Vulgaris results
from as changed in the keratinization pattern in the hair
follicle. The secretion is blocked. Lesions are a result of
interaction between bacteria and hormones. Cleocin T
helps kill this bacteria. Isotretinoin inhibits sebaceous
gland function and keratinization. The estrogen in the birth
control pills help interfere with interaction between the
bacteria and the hormones. The immunosuppressive
cyclosporin has no role in treatment of acne.
Question 7
7. Your patient is a 51 year old male that presents with a lesion in the picture listed below. He
indicates he has not seen a doctor in over 30 years. Which of the following is the best test to order
(other than biopsy) to help look for a potential etiology of this disease?
A.
B.
C.
D.
VDRL
Western Blot Test
Hepatitis C Surface Antigen
Culture patient for HSV
Answer 7
7. Choice B is the correct answer. This patient
has HIV until proven otherwise. This picture is
of a patient with Kaposi Sarcoma. VDRL is a
test for syphilis and this has not been
implicated in relation to Kaposi Sarcoma.
Hepatitis C and HSV have not been implicated
in this disorder either.
Question 8
8. Which of the following skin cancers has the
worse prognosis?
A.
B.
C.
D.
Lentigo Maligna Melanoma
Superficial Spreading Melanoma
Basal Cell Carcinoma
Nodular Melanoma
Answer 8
8. Choice D is the correct answer. Nodular Melanoma
has the worse prognosis because it grows deep. It makes
up about 16% of melanomas. Lentigo Maligna Melanoma
has the best prognosis of the melanomas because it grown
radially and does not extend deep. The most common type
of melanoma is superficial spreading melanoma and this
makes up 70% of all melanomas. Basal Cell Carcinoma is
the slowest growing skin cancer and in general has the
best prognosis.
Question 9
9. Your patient is an 18 year old female recently started on bactrim for a UTI. She comes in with the
rash depicted below and shortness of breath and diffuse wheezing. She is starting having trouble
swallowing. You have ordered albuterol aerosol, solumedrol, and zantac IV. Her vitals are as follow:
BP 75/43, Pulse-112, O2 Sat 91% on 100% NRB. Which of the following is the most important
therapeutic intervention?
A.
B.
C.
D.
Diphenhydramine IV
Epinephrine
Ipratropium Bromide Aerosol
Zantac Drip
Answer 9
9. Choice B is the correct answer. This patient is hypotensive
and exhibiting signs of her airway swelling. This is one of the
major indications for epinephrine. The alpha antagonist
epinephrine will help reduce the swelling and increase the
patient's blood pressure. These cytokines that cause this are
released from the mast cells. Diphenhydramine is indicated but
will not help the patient immediately. There is no evidence to
suggest that ipratropium or a Zantac drip will show benefited
patient outcomes.
Question 10
10. Which organism has been implicated in the rash shown below in the photograph?
A.
B.
C.
D.
Coxsackie Virus
Poxvirus
Parvovirus
HSV
Answer 10
10. Choice B is the correct answer. Molluscum
Contagiosum is caused by the poxvirus.
Cocksackie Virus causes hand, foot and mouth
disease. Fifth's disease is caused by
Parvovirus. HSV is the virus the causes herpes
simplex
