In determining normal blood pressure readings for preschoolers, it is essential to consider the typical ranges that apply to this age group. Blood pressure measurements are influenced by various factors, including age, height, and overall health.

The correct choice reflects a reading that falls within the generally accepted normal range for preschool-aged children. For preschoolers, normal systolic blood pressure typically ranges from 80 to 110 mmHg, and diastolic pressure ranges from approximately 40 to 70 mmHg.

Given this context, the reading of 90/40 is recognized as normal for preschoolers, as both components of this blood pressure reading fit well within the appropriate range for their age. In contrast, other options provide readings that do not align as closely with the established normal values for preschool children, making them less suitable as normal readings for this age group. Understanding these values helps ensure proper health assessments and interventions when necessary.
