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 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.

A. High levels of low-density lipid (LDL) B. Low concentration triglycerides C. Low levels of LDL cholesterol D. High levels of high-density lipid (HDL)

Correct Answer is A

Explanation

A. LDL cholesterol, often referred to as "bad" cholesterol, is a major risk factor for atherosclerosis and PVD. High levels of LDL contribute to the buildup of plaque in the arteries, which can lead to these conditions.
B. While high triglycerides can be a risk factor, low triglycerides are generally not associated with increased risk of atherosclerosis or PVD.
C. Low LDL cholesterol is actually considered beneficial and can reduce the risk of heart disease.
D. HDL cholesterol, often called "good" cholesterol, helps remove LDL cholesterol from the bloodstream. High levels of HDL are actually protective against heart disease and PVD.
