What is the normal blood pressure for elementary school children?

The normal blood pressure range for elementary school children generally falls within a range that can be influenced by various factors including age, height, and weight. The choice of 97/57 reflects an appropriate average within this context, aligning well with established guidelines for children's blood pressure.

Blood pressure is typically lower in younger children than in adults, and numbers within the range of 90-110 systolic and 50-70 diastolic are often considered normal for children in elementary school age. The systolic measurement of 97 is well within the norm, as is the diastolic measurement of 57.

The other choices reflect blood pressure values that may either be too low or too high when compared to standard pediatric norms for elementary-aged children. Therefore, 97/57 is the most accurate option, providing a reliable indication of normal blood pressure for this age group.
