A mother is concerned about her 14-year-old daughter, who is not experiencing pubertal changes. Her height is lower than average for age. She is of normal intelligence. Upon assessment, the nurse practitioner notes extra folds of skin on her neck. What treatment is most appropriate?

Choice A reason: Delayed puberty with features such as lack of secondary sexual characteristics, short stature, and physical anomalies such as extra neck folds may indicate Turner syndrome. Estrogen therapy is essential to induce the development of secondary sexual characteristics and support bone health. Choice B reason: Testosterone is indicated for male hypogonadism or delayed puberty in boys. It is not appropriate for a female patient with delayed puberty. Choice C reason: Doing nothing delays sexual development, potentially affects bone health, and does not address underlying endocrine issues. This is not appropriate management. Choice D reason: Synthetic thyroid addresses hypothyroidism, but this patient presents with delayed puberty and physical features consistent with Turner syndrome rather than thyroid deficiency. Thyroid therapy alone will not initiate puberty.
