Tanner Stages can be used to help determine an adolescent's stage of puberty. You have a 13-year-old female patient. What information does the nurse need to collect in order to use this scale for puberty determination? (Select All that Apply.)

A. Breast development is correct. Tanner staging evaluates thelarche, or breast development, which is a primary indicator of puberty in females. It is assessed on a scale from stage 1 (prepubertal) to stage 5 (mature adult). B. Pubic hair growth is correct. Tanner staging also assesses pubarche, or the development of pubic hair, which progresses in predictable stages. This is independent of breast development and provides additional information about pubertal progression. C. BMI is incorrect. While body mass index may influence the timing of puberty (higher BMI can be associated with earlier puberty), it is not part of the Tanner staging system, which focuses solely on physical sexual characteristics. D. Hip girth is incorrect. Although hip widening occurs during puberty, Tanner staging does not include hip measurements. Physical observation focuses on breast and pubic hair development, not body proportions. E. Age of menarche is correct. While menarche occurs later in puberty, knowing whether it has started helps determine the later Tanner stages (stage 4–5) and overall progression of puberty.
