A nurse is caring for a school-age child who has a systemic disorder and is
receiving antibiotics, immunosuppressants, and corticosteroids. Both of the child's parents have a smoking history.
The child reports soreness in his mouth and refuses to eat.
Inspection of his mouth reveals a white, milky plaque that does not come off with
rubbing.
The nurse should suspect which of the following conditions?

The correct answer is choice D: Pediculosis capitis.

Choice D rationale: Pediculosis capitis is an infestation of head lice, which causes symptoms such as white flakes that do not brush off the hair easily and a rash on the back of the neck. These symptoms are due to the lice feeding on the scalp and laying eggs (nits), which can cause itching and irritation.

Choice A rationale: Folliculitis is an inflammation of the hair follicles, typically caused by bacterial or fungal infections. While it can cause a rash, it is not characterized by white flakes in the hair.

Choice B rationale: Tinea capitis, also known as ringworm of the scalp, is a fungal infection that causes scaly, itchy patches on the scalp. It may lead to hair loss in the affected areas, but it does not typically cause white flakes that do not brush off the hair.

Choice C rationale: Impetigo contagiosa is a highly contagious bacterial skin infection that causes blisters or sores on the skin. It does not involve white flakes in the hair and primarily affects exposed skin rather than the scalp.

A.Allowing an infant with a cast for DDH to stand in the crib could place undue stress on the hips and may not be safe, depending on the type of cast and the stability of the condition. Most spica casts will not allow the child to stand, walk or bear any weight.

B.Providing a small electronic toy can help stimulate the infant's sensory and cognitive development. At 10 months old, infants are curious and responsive to interactive toys that can engage their senses and promote fine motor skills and cognitive development.

C.Tie colorful latex balloons to the side of the crib.: While colorful objects can be visually stimulating, latex balloons pose a choking hazard if they burst or are chewed on by the infant. It is safer to use other forms of visual stimulation, such as colorful toys or mobiles.

D.Change the infant's diaper as soon as soiling occurs.: While it is essential to keep the infant clean and dry to prevent skin irritation and infection, this action, although necessary, does not directly promote growth and development. It is a basic care measure rather than a developmental strategy.
