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.

Correct Answer: B

The antibiotic needs to be administered systemically. Incision and drainage of severe lesions presents a risk of spreading infection or making the lesion worse.
What is the primary treatment for warts?
- A. Vaccination
- B. Local destruction
- C. Corticosteroids
- D. Specific antibiotic therapy
Correct Answer: B
Rationale: Local destructive therapy is individualized according to location, type, and number; surgical removal, electrocautery, curettage, cryotherapy, caustic solutions, x-ray treatment, and laser therapies are used. Vaccination is prophylaxis for warts, not a treatment. Corticosteroids and specific antibiotic therapy are not effective in the treatment of warts.
