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

Itching and scratching of the head

Patchy areas of hair loss

Firmly attached white particles on the hair

Thick, yellow-crusted lesions on a red base

Answer and Explanation

The Correct Answer is C

A. Itching and scratching of the head. While itching is a common symptom, it is not a definitive sign of head lice. Other conditions (e.g., dandruff, seborrheic dermatitis, or dry scalp) can also cause itching.

B. Patchy areas of hair loss. Hair loss is not a characteristic sign of head lice. It may indicate alopecia areata or tinea capitis (scalp ringworm) instead.

C. Firmly attached white particles on the hair. The presence of nits (lice eggs) that are firmly attached to the hair shaft near the scalp is a definitive sign of pediculosis capitis. Nits do not flake off like dandruff and are difficult to remove.

D. Thick, yellow-crusted lesions on a red base. This describes impetigo, a bacterial skin infection, not head lice.

Correct Answer is C

Explanation

A. 5th Intercostal Space, Midclavicular Line. This is the location for the apical pulse (PMI) at the mitral area, not the aortic valve.

B. 2nd Intercostal Space, Left Sternal Border. This is the location of the pulmonic valve, not the aortic valve.

C. 2nd Intercostal Space, Right Sternal Border. The aortic valve is best auscultated at the right second intercostal space, next to the sternum.

D. 3rd Intercostal Space, Left Sternal Border. This is the Erb’s point, which provides equal S1 and S2 sounds, but it is not the best location for auscultating aortic valve dysfunction.

A. Identify when the client first noticed the lesion. B. Photograph the lesion for the client's medical record. C. Instructing the client on the use of daily sunscreen products. D. Document the client's history of skin allergies.

Correct Answer is A

Explanation

A. Identify when the client first noticed the lesion. Determining onset and duration helps assess whether the lesion is new, growing, or concerning for malignancy.

B. Photograph the lesion for the client's medical record. While documentation is important, assessing history and changes in the lesion takes priority.

C. Instructing the client on the use of daily sunscreen products. Sunscreen is essential for prevention, but identifying and assessing the lesion comes first.

D. Document the client's history of skin allergies. While important, it does not take priority over determining how long the lesion has been present and whether it is changing.
