- B. Oral or parenteral antibiotics
- C. Topical application of an antibiotic
- D. Incision and drainage of severe lesions
Correct Answer: B

The nurse should know what about Lyme disease?
- A. Very difficult to prevent
- B. Easily treated with oral antibiotics in stages 1, 2, and 3
- C. Caused by a spirochete that enters the skin through a tick bite
- D. Common in geographic areas where the soil contains the mycotic spores that cause the disease
Correct Answer: C
Rationale: Lyme disease is caused by Borrelia burgdorferi, a spirochete spread by ticks. The early characteristic rash is erythema migrans. Tick bites should be avoided by entering tick-infested areas with caution. Light-colored clothing should be worn to identify ticks easily. Long-sleeve shirts and long pants tucked into socks should be the attire. Early treatment of erythema migrans (stage 1) can prevent the development of Lyme disease. Lyme disease is caused by a spirochete, not mycotic spores.

Rationale: Lymphangitis is frequently seen in cellulitis. If it is present, hospitalization is usually required for parenteral antibiotics. Lymphangitis is not associated with folliculitis, impetigo, or staphylococcal scalded skin.
When giving instructions to a parent whose child has scabies, what should the nurse include?
- A. Treat all family members if symptoms develop.
- B. Be prepared for symptoms to last 2 to 3 weeks.
- C. Carefully treat only areas where there is a rash.
- D. Notify practitioner so an antibiotic can be prescribed.
Correct Answer: B
Rationale: The mite responsible for the scabies will most likely be killed with the administration of medications. It will take 2 to 3 weeks for the stratum corneum to heal. That is when the symptoms will abate. Initiation of therapy does not wait for clinical symptom development. All individuals in close contact with the affected child need to be treated. Permethrin, a scabicide, is the preferred treatment and is applied to all skin surfaces.
