Which of the following is a sign of instability in a pediatric patient during transport?

An elevated heart rate in a pediatric patient during transport is indeed a sign of instability. In pediatric patients, vital signs are critical indicators of their overall condition. An increased heart rate can suggest several underlying issues, such as hypovolemia, fever, pain, anxiety, or even a compensatory mechanism in response to other physiological stresses.

Monitoring the heart rate is essential, as it helps guide treatment and intervention during transport. A significant deviation from the normal heart rate range can signal that the child is experiencing distress and may require immediate attention. Therefore, recognizing an elevated heart rate as a sign of instability is crucial for providers in the pediatric transport setting.

In contrast, stable blood pressure, a regular respiratory rhythm, and consistent oxygen saturation levels indicate that the patient is maintaining appropriate physiological function, which suggests a level of stability rather than instability.
