(VERIFIED AND UPDATED)
Mode of transmission for parasitic skin infections - ANS Close direct skin contact.
Clinical presentation for Scabies - ANS Intense itching, worse at night. Burrows noted
between webs of fingers.
Commonly prescribed medications for Scabies - ANS Permethrin Cream 5% (Elimite) is the
first-line treatment. Safe in 2 months and older. Apply to all areas from neck down and leave on
for 8-12 hours. Repeat application in 1 week. May repeat a third time in another week. Follow
up in 1 week.
Antihistamines and topical steroids if the pruritis is bad.
What should you include in the patient education to prevent spreading of the various parasitic
skin problems? - ANS Avoid close contact. Wash all bedding, clothing, cloth items, and stuffed
animals in hot water. All close contacts family members, people you live with and sexual
partners need to be treated as well.
Which bacterial skin infection is considered highly contagious? - ANS Impetigo
What is the "classic" presentation of impetigo? - ANS Honey crusted lesions

,What is the management of a minor case of folliculitis (non-pharmacologic)? - ANS Gentle
cleansing by washing the skin twice a day with antibacterial soap.
What are the commonly prescribed medications for folliculitis? - ANS Mupirocin (Bactroban)
2% ointment or cream, TID, 5-14 days, for secondarily infected skin lesions.
Mupirocin (Bactroban) twice daily for 5 days in the nose for people with recurrent folliculitis to
clear the colonization of S. Aureus.
Furuncles - ANS Initially appear small (0.5-1 cm), red, tender, indurated nodule. As it grows it
develops a central yellow plug. They eventually rupture spontaneously. Fluctuant or larger
furuncles should be treated with I&D and covered with a simple dry sterile dressing. Patients
should be instructed to use warm compresses twice daily to encourage drainage of pus.
Carbuncles - ANS Initially appear as multiple furuncles and develops into a large,
erythematous lump and must be drained before healing will take place and this typically occurs
spontaneously within 2 weeks. Carbuncles frequently require I&D and need systemic antibiotics
and a referral. Antibiotics include: TMP-SMX (MRSA converage), dicloxacillin, cephalexin, or
doxycycline.
A gram stain is recommended to check for MRSA strains.
What are the considerations when determining treatment for cellulitis? - ANS Severe
infections, infections around the eyes, or systemic involvement (fever & chills),
immunocompromised should be sent to the ED for inpatient IV treatment.
Mild cases can be treated with PO antibiotics that should show improvement within 48-72
hours. Penicillin VK, dicloxacillin, clindamycin, or cephalexin for 5 days.
Infected human & animal bites need to be treated with amoxicillin-clavulanic acid (Augmentin)
for 2 weeks. Prophylaxis treatment for human & animal bites (within 6 hours) amoxicillin-
clavulanic acid (Augmentin) for 3-5 days.
HSV - ANS grouped vesicles on an erythematous base, followed by ulcers or erosions that
crust over with honey color. Lesions typically heal in 7-10 days. Mouth, face, or genitals.
@2026/2027 ALLRIGHTS RESERVED.
, Diagnostic tests for HSV - ANS Viral Culture Gold Standard & PCR tests are standard for
diagnosis. Vesicle fluid can be cultured with 72 hours of outbreak. Tzanck smear. HIV testing is
advisable in HSV-2 patients.
Herpetic keratoconjunctivitis - ANS requires immediate referral to an ophthalmologist.
HSV-2 Genital lesion treatment - ANS Treated with oral antivirals Valacyclovir or famciclovir.
Warm compresses and oatmeal sitz baths can help promote comfort and healing. Urinate into a
warm bath. Increase fluid intake and rest.
HSV-1 oral lesion treatment - ANS Acetaminophen to control pain. Ice or lip ointments like
Blistex. OTC docosanol (abreva) 10% cream applied 5 times a day. For more extensive lesions,
penciclovir (Denavir) 1% cream applied every 2 hours while awake. Extensive oral lesions may
require lidocaine, and acyclovier oral suspension 200mg/5mL, rinse mouth with 1 teaspoon and
swallow five times a day.
HSV Patient education - ANS Begin antiviral at the first sign of tingling or burning.
No sharing of towels, silverware, or glasses. Wash hands frequently.
Avoid sex until lesions are healed, Use condoms every time to avoid viral spread.
Which dermatitis is an inherited skin reaction that begins in infancy - ANS Atopic dermatitis
What is the "atopic triad?" - ANS Atopic eczema, asthma, and allergies
What dermatitis is associated with the expression "the itch that rashes?" - ANS Atopic
dermatitis
What is the objective finding with atopic dermatitis? - ANS Begins in infancy on cheeks, face,
and upper extremities. Erythema is often seen before pruritis. Flexural eczema seen between 4-
10 antecubital fossa, popliteal fossa, and neck. Adults: face, neck, upper chest, genital area and
hands. Excoriated maculopapular lesions. Oozing and crusting.
