What condition is identified by the genetic abnormality XXY?

• A. Turner syndrome
• B. Klinefelter syndrome
• C. Down syndrome
• D. Prader-Willi syndrome

Answer: (B)

Klinefelter syndrome is identified by the genetic abnormality XXY. This condition occurs when a male has an extra X chromosome, resulting in the total chromosomal composition being 47 rather than the typical 46. Individuals with Klinefelter syndrome often display symptoms such as reduced testosterone levels, delayed or incomplete puberty, and infertility. Other features can include taller stature, reduced muscle mass, and breast tissue development.

Understanding this condition is vital in women's health care and advanced practice nursing because it can affect family planning, reproductive health, and overall well-being, necessitating a multidisciplinary approach to care. The recognition of this genetic abnormality allows healthcare providers to support affected individuals through hormonal therapies, fertility treatments, and psychological counseling, thus improving their quality of life.
