What indicates that a 14-year-old girl understands the timeline for starting menstruation in relation to Tanner stages?

The statement that signifies the 14-year-old girl’s understanding of the timeline for starting menstruation in relation to Tanner stages is the one acknowledging that getting her period at 16 would still be considered normal. This aligns with the knowledge that menstruation typically begins during Tanner stage 3 or 4 of sexual maturity, which can occur anywhere from ages 9 to 16.

Her awareness that a later onset of menstruation is within the range of normal development reflects an understanding of the variability in physical development among individuals. This insight indicates that she is familiar with the expected development timeline in relation to Tanner stages, appreciating that there is a range of timing for the onset of menstruation, which can greatly differ from one individual to another based on genetic and environmental factors.

This knowledge supports coping and self-acceptance, as she recognizes that not having started her period yet does not necessarily indicate a problem. In contrast, the other statements lack this understanding. Statements about seeing a specialist or needing a pregnancy test suggest concerns or misconceptions about her health rather than an acknowledgment of normal developmental variations.
