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.
