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.
