A nurse is checking a school-age child for pediculosis capitis. Which of the following findings is a definitive indication of this condition?

Choice A rationale Pediculosis capitis, also known as head lice, is a common condition in children. One of the definitive indications of this condition is the presence of firmly attached white particles on the hair, which are the eggs or “nits” of the lice. Choice B rationale While itching and scratching of the head can be a symptom of pediculosis capitis, it is not a definitive indication as it can be caused by other conditions such as dandruff or dermatitis. Choice C rationale Patchy areas of hair loss are not typically associated with pediculosis capitis. They could indicate a different condition, such as alopecia areata or tinea capitis. Choice D rationale Thick yellow-crusted lesions on a red base are not a symptom of pediculosis capitis. This description is more consistent with impetigo, a bacterial skin infection.
