In a typical 28 days female reproductive cycle, on which day following the beginning of the menstrual period is the level of luteinizing hormone most likely to be highest?

  • A. Day 5
  • B. Day 7.
  • C. Day 14.
  • D. Day 14.
Correct Answer: C

Rationale: The correct answer is C (Day 14). On day 14 of a typical 28-day female reproductive cycle, the level of luteinizing hormone (LH) is most likely to be highest. This is because day 14 corresponds to ovulation, which is triggered by a surge in LH. Ovulation occurs when the mature egg is released from the ovary, and LH surge is crucial in this process. Therefore, the peak level of LH is expected on day 14.

Incorrect Choices:
A: Day 5 - Too early in the cycle for LH surge.
B: Day 7 - Still early in the cycle for LH surge.
D: Day 21 - LH surge typically occurs around day 14, not day 21.

  • A. destroying all affected tumor tissue

Which one of the following is NOT a (vas) deferens, epididymis, component of semen?

  • A. sperm
  • B. epididymis, seminal glands
  • C. seminal fluid
  • D. prostatic fluid
Correct Answer: A

Rationale: The correct answer is A: sperm. Sperm is not a component of semen; it is the male reproductive cell. Semen is composed of fluids from the epididymis, seminal glands, and prostate, which provide nourishment, protection, and transportation for sperm. The epididymis stores and matures sperm, seminal glands produce seminal fluid, and the prostate contributes prostatic fluid. Sperm is only a part of semen and not a component of it. Therefore, choice A is the correct answer.

The ovary connects by ligaments to:

  • A. the uterus;
  • B. the Fallopian tubes;
  • C. the rectum;
  • D. the pelvic walls;
Correct Answer: A

Rationale: The correct answer is A: the uterus. The ovary connects to the uterus via ligaments called ovarian ligaments. This connection is essential for the transfer of eggs from the ovary to the uterus during the menstrual cycle and for providing support to the ovary. The other choices are incorrect as the ovary does not directly connect to the Fallopian tubes (B), rectum (C), or pelvic walls (D) via ligaments. The connection to the uterus is crucial for reproductive functions and maintaining the structural integrity of the female reproductive system.

In teaching a class of adolescents about sexually transmitted diseases, a nurse includes which information about the human papillomavirus (HPV)?

  • B. Wartlike growths in the genital area are a sign of HPV infection.
  • C. There is a specific blood test needed to screen for HPV.
  • D. Heavy, purulent vaginal discharge is the primary sign of HPV.
Correct Answer: B

Rationale: The correct answer is B: Wartlike growths in the genital area are a sign of HPV infection. This is because HPV often manifests as genital warts. HPV is a common sexually transmitted infection that can lead to various health issues, including genital warts and certain types of cancers. Choices A, C, and D are incorrect because HPV is not fragile, does not require a specific blood test for screening, and does not typically present with heavy, purulent vaginal discharge.
