In the normal child, which general statement is most accurate in comparison with the adult patient?

In normal pediatric physiology, blood pressure tends to be lower than in adults, while both heart rate and ventilatory rate are higher. This reflects several adaptions: the cardiovascular system in children has smaller vessels and a smaller stroke volume, so resting blood pressure is lower and the heart compensates with a faster rate to maintain cardiac output. At the same time, children have a higher metabolic rate and oxygen demand, plus smaller tidal volumes, which means they breathe more rapidly to achieve adequate minute ventilation. So the statement that best fits these differences is that blood pressure is lower, heart rate is higher, and ventilatory rate is higher in children compared with adults. In contrast, adults typically have higher blood pressure, lower heart rate, and lower respiratory rate at rest.
