Delayed sexual development in an adolescent female who is very thin may be associated with:
Klinefelter syndrome.
Turner syndrome.
anorexia nervosa.
hyperthyroidism.
The Correct Answer is C
Rationale:
A. Klinefelter syndrome affects males, leading to hypogonadism and delayed puberty, not females.
B. Turner syndrome is associated with short stature and gonadal dysgenesis, but it is a chromosomal condition rather than related to body weight or nutrition.
C. Anorexia nervosa can cause delayed sexual development in adolescent females due to malnutrition and low body fat, which disrupts hypothalamic-pituitary-ovarian axis function, leading to delayed puberty or amenorrhea.
D. Hyperthyroidism generally accelerates metabolism and can sometimes cause early menarche or menstrual irregularities, but it is not typically associated with delayed sexual development.

A. Most children do not achieve spontaneous resolution of enuresis by age 4; it is more common for spontaneous resolution to occur gradually over time, often by age 6–7 years.
B. Bedwetting alarms and behavioral therapy are effective first-line interventions for enuresis, helping children recognize bladder fullness and establish bladder control.
C. Nighttime (nocturnal) enuresis is more common than daytime (diurnal) enuresis in children.
D. Enuresis is usually a normal developmental variation and does not typically indicate an underlying disease in otherwise healthy children; extensive urological workup is not routinely required unless other concerning symptoms are present.
Correct Answer is B
Explanation
Rationale:
A. Klinefelter syndrome affects males and is characterized by tall stature, small testes, and hypogonadism, not delayed female puberty.
