Following an outdoor field trip, a student reports to the teacher that he has a tick imbedded in his skin. The appropriate procedure for the teacher to follow upon discovering the imbedded tick is to:
  1. Have the student call his parents to inform them that he has possibly contracted Lyme disease.
  2. Leave the tick alone and inform the student that he needs to visit his doctor as soon as possible.
  3. Have the school nurse remove the tick from the student immediately and save it for identification.
  4. Encourage the student to remove the tick himself and report the matter to his parents.
Explanation
Correct Response: C. Having a medical professional and not the student (D) carefully remove the tick is the best approach. This ensures that the entire tick will be removed properly and that it can be identified. This is important as Lyme disease is carried by deer ticks, but not dog ticks. Scaring parents with misinformation (A) is unprofessional conduct for a teacher and could lead to unnecessary medical treatments. The probability of acquiring Lyme disease from an infected deer tick embedded in the skin increases dramatically after 24 hours. For this reason, telling the student to leave the tick in until he sees his doctor (B) is a bad idea.
