The school nurse is conducting pediculosis capitis checks. A child with a positive head check would have which finding?

Lesions in the scalp that extend to the hairline or neck.

Circular lesion with raised edges and central clearing and itching

White sacs attached to the hair shafts in the occipital area

Maculopapular lesions behind the ears.

Answer and Explanation

The Correct Answer is C

A.   While scratching due to lice can lead to irritation and lesions, this finding is not specific to pediculosis capitis. Lesions extending to the hairline or neck could be caused by various conditions, such as eczema or dermatitis, rather than lice infestation.
B.   This description is more characteristic of tinea capitis (scalp ringworm) rather than pediculosis capitis. Tinea capitis presents as circular patches with raised edges and may cause itching, but it is not caused by lice.
C.   In cases of pediculosis capitis, the white sacs refer to nits (lice eggs), which are commonly found attached to hair shafts, especially around the occipital area (back of the head). Nits are oval and may be mistaken for dandruff but are firmly attached to the hair.
D.   While maculopapular lesions can be a result of scratching, they are not a typical finding in pediculosis capitis. Such lesions might indicate another skin condition or an allergic reaction rather than an infestation of lice.

Correct Answer is D

Explanation

A. While it may be important to inform the parents later, this is not the immediate priority. The first step should be to assess and manage the current situation before involving the parents.
B. This is a reasonable action to help soothe the itching and irritation caused by contact dermatitis. However, before applying compresses, it’s crucial to ensure that the area is clean and that there is no potential for worsening the condition.
C. This may be necessary if the reaction is severe or worsening, but in this case, the student is exhibiting signs consistent with contact dermatitis, which can often be managed effectively at school without immediate medical intervention.
D. Washing the affected area with soap and water helps remove any potential irritants or allergens that may be causing the dermatitis. This action can help prevent the condition from worsening and relieve some of the symptoms.

A. Avoid cleansing the area before application of the cream. B. Apply a thin layer of cream and rub it into the area thoroughly. C. Apply the cream over the entire body. D. Apply a thick layer of cream to affected areas only.

Correct Answer is B

Explanation

A. The area should be cleansed gently before applying the cream to remove any irritants and allow for better absorption of the medication. Proper cleansing can help enhance the effectiveness of the corticosteroid.
B. Topical corticosteroids should be applied in a thin layer to the affected area and gently rubbed in. Applying too much can increase the risk of side effects, and a thin application ensures better absorption without overwhelming the skin.
C. The corticosteroid should be applied only to the affected areas of the skin, not the entire body. Overuse can lead to systemic absorption and potential side effects, particularly in children, whose skin is more permeable.
D. While it is important to cover the affected areas, applying a thick layer is not recommended. A thin layer is usually sufficient and minimizes the risk of side effects from excessive corticosteroid use.
