A young woman experienced signs of secondary sexual development (puberty) beginning at age 12. She is now approaching her 17th birthday but has not yet begun menstruating. What is the clinic nurse’s best response?

  • A. “Don’t worry, your periods should start soon.”
  • B. “This is a cause for great concern. You could have difficulty conceiving in the future.”
  • C. “Given that other signs of sexual development have occurred, we should schedule an appointment for further assessment.”
  • D. “This is fairly normal. Some young women are just ‘late bloomers,’ and there is no real cause for concern.”
Correct Answer: C

Rationale: The correct answer is C. Given the young woman's delayed menarche despite signs of secondary sexual development, further assessment is warranted to rule out any underlying medical conditions affecting her menstrual cycle. This approach ensures appropriate evaluation and potential intervention if necessary.

A: Incorrect. While reassuring, it overlooks the need for a thorough assessment in this scenario.
B: Incorrect. Prematurely alarming the individual about future fertility issues without proper evaluation is unwarranted.
D: Incorrect. While some young women may be "late bloomers," it is essential to verify this through a professional assessment to rule out any underlying issues.

This timeframe is important to ensure the patient receives the full benefit of the vaccine. Choice A is incorrect because the HPV vaccine is not available in oral form. Choice B is incorrect as the HPV vaccine series usually consists of two or three injections, not just two. Choice D is incomplete and does not provide any relevant information.

Pitocin (A) is responsible for uterine contractions. Estrogen (C) and progesterone (D) are involved in pregnancy maintenance but do not directly stimulate milk production.
