Human Reproductive System Questions
Question 1 of 5
In teaching a class of adolescents about sexually transmitted diseases, a nurse includes which information about the human papillomavirus (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.
Question 2 of 5
A woman calls the clinic because she is having an unusually heavy menstrual flow. She tells the nurse that she has saturated three tampons in the past 2 hours. The nurse estimates that the amount of blood loss over the past 2 hours is _____ mL.
Correct Answer: B
Rationale: The correct answer is B (40 to 60 mL) because a typical tampon can absorb around 20 mL of blood. If the woman has saturated three tampons in 2 hours, that would be 3 tampons x 20 mL each = 60 mL. This indicates a significant blood loss. The other choices are incorrect because they do not account for the volume of blood absorbed by the tampons and underestimate the amount of blood loss. Choice A is too low, choices C and D are too high. The correct estimation of 40 to 60 mL aligns with the information provided and reflects the severity of the situation.
Question 3 of 5
Testosterone is secreted by
Correct Answer: A
Rationale: Testosterone is secreted by Leydig cells in the testes. Leydig cells are interstitial cells located between the seminiferous tubules. They are responsible for producing and secreting testosterone, which plays a crucial role in stimulating the development of male secondary sexual characteristics and maintaining male reproductive functions. Sertoli cells provide nourishment and support for developing sperm cells but do not secrete testosterone. Spermatocytes and early spermatids are involved in the process of spermatogenesis and do not secrete testosterone. Therefore, the correct answer is A because Leydig cells are specifically known for their role in testosterone production.
Question 4 of 5
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?
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.
Question 5 of 5
Endometrium
Correct Answer: B
Rationale: The correct answer is B: Stratum functionalis is shed during menstrual phase. The endometrium is composed of two layers - the stratum functionalis and the stratum basalis. The stratum functionalis is the layer that undergoes cyclic changes during the menstrual cycle, thickening and then shedding during menstruation. This process is essential for preparing the endometrium for potential implantation of a fertilized egg. Choice A is incorrect because the endometrium is actually lined by simple columnar epithelium with ciliated cells. Choice C is incorrect because the decidua is the name for the endometrium during pregnancy, but it is not specific to forming the decidua of the placenta. Choice D is incorrect because the arcuate artery is a branch of the uterine artery that runs along the myometrium, not penetrating the endometrium directly.
