Q. A parent asks the nurse about head lice (pediculosis capitis) infestation during a visit to the clinic. Which of the following symptoms should the nurse tell the parent is most common in a child infected with head lice?

A. Itching of the scalp.
B. Scaling of the scalp.
C. Serous weeping on the scalp surface.
D. Pinpoint hemorrhagic spots on the scalp surface.

Correct Answer: A

Explanation: The most common characteristic of head lice infestation (pediculosis capitis) is severe itching. The head is the most common site of lice infestation. If the child scratches, scaling may occur. Itching also occurs when lice infest other parts of the body. Scratch marks are almost always found when lice are present. Weeping on the scalp surface may be an indication of an infection or other dermatologic condition. Hemorrhagic spots are not a symptom of head lice, but may be caused by scratch marks.
