During a physical exam, which vital sign finding in a preschooler should be a concern?

In preschoolers, normal respiratory rates typically range from about 20 to 30 breaths per minute. When the respiratory rate is 30 breaths per minute, it is at the higher end of the normal range but can sometimes be considered tachypnea depending on the child's condition, activity level, and overall health status.

A respiratory rate of 30 per minute raises a concern if it is accompanied by signs of distress, abnormal lung sounds, or if the child is exhibiting other symptoms such as lethargy or cyanosis. Factors like fever, anxiety, or physical activity can also affect this rate. Therefore, while a rate of 30 is still considered within the realm of normal for preschoolers, it warrants closer observation and potential intervention, especially if other respiratory issues are present, making it a more concerning finding.

In contrast, the other vital sign readings provided are within expected parameters for a preschool-aged child. A temperature of 36.5°C (97.7°F) is normal, a heart rate of 90 beats per minute falls comfortably within the normal range for preschoolers (which can be between 80 to 120 beats per minute), and a respiratory rate of 25 breaths per minute also falls within the normal threshold. Therefore, the
