The correct choice is heart rate and blood pressure, as both vital signs play a significant role in assessing dehydration in children.

In the context of dehydration, heart rate can increase as the body tries to maintain adequate circulation despite reduced blood volume. When a child is dehydrated, the heart compensates by pumping faster to ensure that vital organs continue to receive sufficient blood flow. This compensatory mechanism highlights the importance of monitoring heart rate during assessments.

Blood pressure, on the other hand, can indicate the severity of dehydration. In mild to moderate dehydration, blood pressure may remain within normal limits. However, if the child becomes severely dehydrated, hypotension (low blood pressure) may occur due to the drop in circulating blood volume, signaling the need for immediate intervention.

Together, these two vital signs provide crucial insights into the child's hydration status and overall hemodynamic stability, making them essential components in evaluating dehydration.
