Final answer:
After menarche, a girl has typically reached about 95% of her mature height, indicating that significant growth in height may not continue much longer, although some growth can still occur. The correct option is C.
Step-by-step explanation:
A 13-year-old girl asked the nurse how much taller she will get after having observed that she grew about 5 cm per year but recently experienced a growth of 10 cm in the past year, and that menarche has occurred.
The nurse should inform her that approximately 95% of mature height is achieved when menarche occurs. Girls typically start their pubertal growth spurt a year or two earlier than boys, which also finishes earlier.
Therefore, after menarche, which usually occurs towards the end of the pubertal growth phase, there isn't a significant amount of height growth to be expected.
During puberty, both boys and girls experience a rapid increase in height, known as the growth spurt. This growth spurt typically lasts for about 1 year in girls.
The girl in question has been growing about 5 cm per year, but grew 10 cm this past year. This increase in growth may be attributed to the pubertal growth spurt she is currently experiencing.
However, it's important to note that some growth can still occur after menarche, though it may be limited. The correct option is C.
