- A. Pouch of Douglas
- B. Rectum
- C. Perineal body

- B. Willingness to terminate pregnancy
- C. Expulsion of products of conception after the 28th week of gestation
- D. Expulsion of products of conception before the 28th week of gestation
Correct Answer: D
Rationale: Abortion is defined as the expulsion of products of conception before the 28th week of gestation. Choice A is incorrect as it describes bleeding in early pregnancy, not the definition of abortion. Choice B is incorrect as it refers to the willingness to terminate a pregnancy rather than the actual act of expulsion. Choice C is incorrect as it defines abortion as the expulsion of products of conception after the 28th week of gestation, which is considered a stillbirth.
Cryptorchidism is a condition where _________.
- A. One or both testes are not developed
- B. One or both testes fail to descend into the scrotum
- C. One or both testes are not formed
- D. None of the above
Correct Answer: B
Rationale: Cryptorchidism is a condition where one or both testes fail to descend into the scrotum. This means that the testes do not properly move from the abdomen into the scrotum during fetal development. Choice A is incorrect because the issue is not about development but descent. Choice C is incorrect as it implies that the testes were never formed, which is not the case in cryptorchidism. Choice D is incorrect as cryptorchidism does involve the testes but rather their descent into the scrotum.
Oligomenorrhea is defined as a cycle longer than:
- A. 28 days
- B. 30 days

Similarly, 30 days (Choice B) and 40 days (Choice D) are also within the normal range. The correct definition of oligomenorrhea specifically refers to cycles longer than 35 days, making Choice C the correct answer.
