What is considered a normal range for blood pressure in children?

The normal range for blood pressure in children is best represented by the values of 90/60 mmHg to 120/80 mmHg. This range accommodates the varying levels of normal blood pressure dependent on the child's size, age, and developmental stage. Blood pressure norms are not constant and can change significantly as children grow.

In this context, the lower threshold (90/60 mmHg) allows for healthy physiological variations, particularly in younger or smaller children, while the upper limit of 120/80 mmHg aligns more with values seen in older children and adolescents who are approaching adult norms. This range effectively captures the variability in blood pressure measurements across the pediatric population, making it applicable to a wide age group.

Other ranges, such as those provided in the other options, do not accurately reflect the established pediatric guidelines and would either be considered too low or too high for normal readings in children. This information is critical for healthcare providers to ensure proper monitoring and management of blood pressure in pediatric patients.
