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. This is not a typical preoperative instruction for retinal detachment surgery. Pupil constriction is not directly related to the procedure.
B. This is crucial to prevent further damage to the retina. Sudden head movements can exacerbate the detachment.
C. Cool compresses are not typically recommended before retinal detachment surgery. They may not have a significant impact on the condition.
D. While eye patches might be used post-operatively to protect the eyes, it's not a common preoperative instruction.

Correct Answer is ["5.3"]

Explanation

1 kilogram equals 2.2 pounds.

The preschooler weighs 29 pounds, which is approximately 13.18 kilograms (29/2.2). The order is for 40 mg/kg/day

13.18 kg * 40 mg/kg = 527.2 mg/day.

Since the medication is to be administered every 12 hours, divide this daily dosage by 2 to get the per dose amount: 527.2 mg/day / 2 = 263.6 mg/dose.

Now, using the concentration of the elixir, which is 250 mg/5 mL, set up a proportion to find out how many milliliters are needed for the prescribed dose: 250 mg : 5 mL = 263.6 mg : X mL.

Solving for X gives us (263.6 mg * 5 mL) / 250 mg = 5.272 mL per dose.

Rounding to the nearest tenth, the nurse should administer 5.3 mL per dose.
