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.

The correct answer is choice C. 6.8 to 7.7 kg (15 to 17 lb).

Choice A rationale:

This weight range is above the average for a 6-month-old infant. According to growth charts, the 50th percentile weight for a 6-month-old male is approximately 7.9 kg (17 lb 8 oz), and for a female, it’s about 7.3 kg (16 lb 1 oz). Therefore, 8.6 to 9.5 kg would be considered above average and not the anticipated weight for most infants.

Choice B rationale:

This weight range is below the average for a 6-month-old infant. The average weight at 6 months is significantly higher than 4.1 to 5 kg, as infants are expected to double their birth weight by 5 months of age. Therefore, an infant weighing between 9 to 11 lb at 6 months would be considered underweight.

Choice C rationale:

This weight range is within the average for a 6-month-old infant. As mentioned, the 50th percentile weights for 6-month-old infants are approximately 7.9 kg for males and 7.3 kg for females. This choice falls within the expected weight gain trajectory where an infant is anticipated to double their birth weight by 5 months and then gain an additional pound or so by 6 months.

Choice D rationale:

This weight range is significantly above the average for a 6-month-old infant. It is well above the 95th percentile for this age group and would be considered unusual without underlying health conditions that could contribute to such a weight at this age. An infant weighing between 23 to 25 lb at 6 months would be exceptionally rare and likely indicative of an abnormal growth pattern.
