A school nurse is completing routine health evaluations for school-age children. Which of the following manifestation should alert the nurse to the possibility of pediculosis capitis?

A. "Take a hot shower daily to relieve itching."

This instruction is not recommended because hot water can exacerbate itching and worsen the condition. Hot showers can strip the skin of its natural oils, leading to further dryness and irritation, which may aggravate the itching associated with scabies.

B. "Wear loose fitting clothing while you are experiencing itching."

This instruction is appropriate because loose-fitting clothing can help minimize friction and irritation on the skin affected by scabies. Tight clothing can exacerbate itching and discomfort, so wearing loose clothing can provide relief and allow the skin to breathe.

C. "Add fabric softener to linens when they are washed."

This instruction is not recommended because fabric softeners may contain chemicals or fragrances that can irritate the skin, especially for someone with pruritus or scabies. It's best to use gentle, fragrance-free laundry detergent to wash linens and clothing to minimize potential irritation.

D. "Use a soft bristle brush to gently rub the affected areas."

This instruction is not recommended because using a brush, even if it has soft bristles, can further irritate the skin and potentially spread the scabies mites to other areas of the body. It's best to avoid any abrasive or vigorous rubbing of the affected areas and instead focus on gentle cleansing and moisturizing techniques.

A. Ridged abdomen - This finding is not typically associated with Hirschsprung disease. Instead, the abdomen may appear distended or bloated due to the accumulation of stool in the colon.

B. Ribbonlike, foul-smelling stools - This is a characteristic finding in Hirschsprung disease. Because the affected portion of the colon lacks nerve cells (ganglion cells) responsible for peristalsis, stool movement is impaired, leading to the passage of narrow, ribbonlike stools. These stools may also have a foul odor due to bacterial overgrowth in the affected area.

C. Projectile vomiting - Projectile vomiting is not a common finding in Hirschsprung disease. It is more commonly associated with conditions such as pyloric stenosis or gastroesophageal reflux.

D. Chronic hunger - Chronic hunger is not a typical finding in Hirschsprung disease. Instead, affected infants may experience feeding difficulties, constipation, and failure to thrive due to the obstruction of stool in the colon. They may also exhibit symptoms such as abdominal distention, vomiting, and refusal to feed.
