Nokea
Where does the ovum receive the sperm?
- A. Animal pole
- B. Vegetal pole
- C. Zona pellucida
- D. None of the above
Correct Answer: C
Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.

Polymenorrhoea is defined as:
- A. Menstruation that occurs at an interval less than 35 days
- B. Menstruation that occurs at an interval greater than 35 days
- C. Menstruation that occurs at an interval less than 21 days
- D. Menstruation that occurs at an interval greater than 21 days
Correct Answer: C
Rationale: Polymenorrhoea is defined as menstruation that occurs at intervals shorter than 21 days. Choice A is incorrect because it describes menstruation at intervals less than 35 days. Choice B is incorrect as it describes menstruation at intervals greater than 35 days. Choice D is incorrect as it describes menstruation at intervals greater than 21 days.
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.
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.
Which policy was formally launched to target reducing population growth, making family planning services available, accessible, and affordable to all eligible users?
- A. The reproductive health policy
- B. The ministry of health policy
- C. Gender and health policy
- D. The national population policy
Correct Answer: D
Rationale: The correct answer is D, the national population policy. This policy was specifically launched to address population growth by providing access to family planning services. Choices A, B, and C are incorrect because they do not directly focus on population control and family planning services, which are the primary objectives of the national population policy.
Causes of metrorrhagia include:
- A. Cervical carcinoma
- B. Uterine polyp
- C. Cervical endometriosis
- D. Infections like Chlamydia
Correct Answer: A
Rationale: Metrorrhagia refers to irregular menstrual bleeding that occurs between periods. Cervical carcinoma, a type of cancer that develops in the cervix, can lead to metrorrhagia. Uterine polyps, which are growths attached to the inner wall of the uterus, can also cause abnormal bleeding. While infections like Chlamydia can cause abnormal vaginal bleeding, they are not common causes of metrorrhagia. Cervical endometriosis, although a possible gynecological condition, is not a typical cause of metrorrhagia. Therefore, the correct answer is cervical carcinoma as it is a known cause of metrorrhagia, making the other options incorrect.
