Question

a growth chart is used in monitoring the growth and development of a child. the star on the chart represents a girl who is at the doctor for a routine check - up. judging by the location of the star, should the doctor conduct tests to examine her pituitary gland? \boxed{no} \textbf{complete} why or why not? \bigcirc her height is within normal range; her pituitary gland is functioning normally. \bigcirc her height indicates a disorder of the pituitary gland. \textbf{done}

Explanation:

The growth chart for girls (2 - 20 years) shows percentile curves. The star (representing the girl) lies within the range of the percentile curves, meaning her height is within the normal range. The pituitary gland is involved in growth hormone production; a normal height range suggests the pituitary is functioning normally, so no tests for pituitary disorder are needed. The first option explains this, while the second incorrectly suggests a disorder.

Answer:

A. Her height is within normal range; her pituitary gland is functioning normally.
