Final answer:
A seven-year-old child in the normal weight range for their age typically falls within the 5th to 85th percentile on a standard growth chart. Percentiles are benchmarks in growth charts used by healthcare professionals to assess a child's growth against the reference population. Option A is the correct answer.
Step-by-step explanation:
The question pertains to growth charts and what percentile range corresponds to a normal weight range for a seven-year-old child. Growth charts are tools used by pediatricians to compare a child's growth to typical development patterns.
A child in the normal weight range would typically fall between the 5th and 85th percentile. These percentiles represent a comparison to the reference population, where a child below the 5th percentile is considered underweight, and above the 85th percentile may be considered overweight.
It is important to note that these percentiles are reference points and a child's growth includes a wide range of factors, including genetics and environment. It is essential to consult a healthcare professional to assess a child's growth over time and in the context of their overall health. According to the information available, the correct answer is option a) 5th to 85th percentile.
