Which 16-year-old female patient is most likely to experience secondary amenorrhea?
Correct Answer: B
Rationale: The correct answer is B because a 16-year-old female with a height of 5 ft 9 in and weight of 180 lb is most likely to experience secondary amenorrhea due to obesity. Excess body fat can disrupt hormonal balance, leading to irregular or absent menstrual cycles. The other choices do not indicate obesity, which is a common cause of secondary amenorrhea in adolescents. Choice A is overweight but not obese, choice C is underweight, and choice D is within a healthy weight range. Therefore, choice B is the most likely candidate for secondary amenorrhea based on the given information.
