Oligomenorrhea is defined as a cycle longer than:
- A. 28 days
- B. 30 days
- C. 35 days
- D. 40 days
Correct Answer: C
Rationale: Oligomenorrhea is defined as a menstrual cycle longer than 35 days. A cycle of 28 days (Choice A) is within the normal range, and not considered oligomenorrhea. 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.

What action does the copper used in Copper T have?
- A. Blastocidal
- B. Bacteriostatic
- C. Bacteriocidal
- D. Spermicidal
Correct Answer: D
Rationale: The correct answer is D, Spermicidal. The copper in Copper T exerts its action by affecting sperm viability and motility, thus preventing fertilization. Choices A, B, and C are incorrect because Copper T primarily works by preventing sperm from reaching and fertilizing the egg, rather than acting on blastocysts, bacteria, or bacteriocins.
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.

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.
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.
