A group of nurses is reviewing the cardiovascular system and its function. Which statement by one of the nurses demonstrates an understanding of a child’s cardiovascular system?

“At birth, the infant’s right and left ventricle are about the same size.”

“The child’s heart doesn’t mature and function like an adult’s until between 8 and 10 years of age.”

“The heart rate of the child decreases whenever the child experiences a fever.”

“Between the ages of 5 and 6, the child’s left ventricle grows to about two times the size of the right.”
