A nurse is reinforcing teaching with the parents of a 10-week-old infant who is scheduled for surgical repair of a cleft lip. Which of the following pieces of information should the nurse include?

Choice A rationale:
The nurse should report the finding of a 6-month-old infant with a spiral fracture to a lower extremity to local authorities. Spiral fractures in infants, especially those who are not yet independently mobile, raise concerns about possible child abuse or non-accidental trauma. The unique pattern of spiral fractures is often associated with twisting forces, which are unlikely to occur accidentally in infants who cannot perform such movements. Reporting such cases is essential to ensure the safety and well-being of the child.
Choice B rationale:
A 9-month-old infant exposed to bedbugs and cellulitis is not an emergency that requires reporting to local authorities. While cellulitis can be serious, it is not an immediate threat to the child's safety, and the focus should be on providing appropriate medical care.
Choice C rationale:
A 4-year-old preschooler with rivalry among siblings does not indicate a need for reporting to local authorities. Sibling rivalry is a common occurrence in families and does not pose a threat to the child's safety. It is a social and developmental issue that can be addressed within the family.
Choice D rationale:
A 24-month-old toddler experiencing occasional incontinence does not require reporting to local authorities. Occasional incontinence can be a normal part of toddler development as they learn to control their bladder. It does not indicate abuse or immediate danger to the child.

Choice A rationale:
Urine osmolality 500 mOsm/kg. Urine osmolality is a measure of urine concentration and is not a reliable indicator of infection. It reflects the kidney's ability to concentrate urine and can vary based on hydration status and other factors. An elevated urine osmolality could suggest dehydration, not necessarily infection.
Choice B rationale:
WBC 17,500/mm3. This is the correct choice. An elevated white blood cell count (WBC) is a hallmark sign of infection. The body's immune response to an infection often includes an increase in WBC count, particularly the neutrophil count. This elevation is known as leukocytosis and is a red flag for infection.
Choice C rationale:
BUN 12 mg/dL. Blood Urea Nitrogen (BUN) measures kidney function and hydration status. While an elevated BUN can indicate dehydration, it is not a specific marker for infection. BUN levels can be influenced by various factors, including diet and renal function.
Choice D rationale:
Urine specific gravity 1.014. Urine-specific gravity reflects the concentration of solutes in urine and the kidney's ability to concentrate or dilute urine. While changes in urine specific gravity can indicate dehydration or overhydration, it is not a direct indicator of infection. An infection is better detected through changes in WBC count and other clinical signs.
