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.

In which part of the fallopian tube is tubal abortion most common?
- A. Ampullary portion
- B. Isthmus
- C. Interstitial portion
- D. Infundibulum
Correct Answer: C
Rationale: Tubal abortion is most common when the ovum implants in the interstitial portion of the fallopian tube. This location is the narrowest part of the tube, making it more prone to obstruction or difficulty in the passage of the fertilized ovum. Choices A, B, and D are incorrect because tubal abortion is more likely to occur in the interstitial portion rather than the ampullary portion, isthmus, or infundibulum of the fallopian tube.
What term is used to refer to the fertilized ovum?
- A. Zygote
- B. Embryo
- C. Foetus
- D. Pregnancy
Correct Answer: A
Rationale: The correct answer is A, Zygote. A zygote is formed when a sperm cell fertilizes an egg cell. It is the initial stage of prenatal development. Choice B, Embryo, refers to the stage of prenatal development after the zygote and before the foetus. Choice C, Foetus, is the stage of prenatal development after the embryo. Choice D, Pregnancy, is a broader term referring to the condition of having a developing baby in the uterus.
Discuss the anatomical/physiological changes in pregnancy under the following: Haematological system
- A. Blood volume and plasma volume increase, red blood cells increase, erythropoietin levels decrease, and leukocyte count increases.
- B. Blood volume and plasma volume decrease, and red blood cells decrease.
- C. No changes occur in the haematological system during pregnancy.
- D. Platelet count remains constant, and no change in coagulation factors.
Correct Answer: A
Rationale: During pregnancy, the haematological system undergoes changes to support the growing fetus. Blood volume and plasma volume increase to accommodate the needs of the developing baby. Red blood cells increase to support the increased oxygen demand. Contrary to the statement, erythropoietin levels actually increase to stimulate red blood cell production. Additionally, leukocyte count increases to help the mother's immune system cope with the changes during pregnancy. Choice B is incorrect as it describes a decrease in blood components, which is not the case in pregnancy. Choice C is incorrect as there are significant changes in the haematological system during pregnancy. Choice D is incorrect as platelet count can fluctuate during pregnancy, and there are changes in coagulation factors to prevent excessive bleeding.
Which one of the following statements is NOT true about menstruation?
- A. The average amount of menstrual flow is 50 to 90 ml.
- B. The menstrual flow constitutes serous fluid, necrotic slough.
- C. The cycle is influenced by the ovarian hormones Estrogen and progesterone.
- D. The menstrual flow has non-clotting blood.
Correct Answer: D
Rationale: The correct answer is D. The statement that menstrual flow has non-clotting blood is incorrect because menstrual blood can indeed clot. Choices A, B, and C are all true statements about menstruation. Choice A reflects the average amount of menstrual flow, choice B describes the components of menstrual flow, and choice C correctly identifies the ovarian hormones that influence the menstrual cycle.
During the menstrual cycle, which hormone maintains the corpus luteum?
- A. Luteinizing hormone
- B. Follicle-stimulating hormone
- C. Progesterone
- D. Relaxin
Correct Answer: A
Rationale: During the menstrual cycle, luteinizing hormone maintains the corpus luteum. The correct answer is A. Luteinizing hormone stimulates the corpus luteum to produce progesterone. Choice B, Follicle-stimulating hormone, is involved in stimulating the growth of follicles in the ovaries. Choice C, Progesterone, is produced by the corpus luteum and plays a role in preparing the endometrium for implantation. Choice D, Relaxin, is involved in processes such as softening the cervix and ligaments during pregnancy, but it is not responsible for maintaining the corpus luteum.
