Reproductive Health Exam
1. Which technique is used to detect HIV/AIDS?
- A. Northern blot and ELISA
- B. Immunoblot and ELISA
- C. Western blot and ELISA
- D. Southern blot and ELISA
Correct answer: C
Rationale: The correct answer is C: Western blot and ELISA. Western blot and ELISA are commonly used techniques in the detection of HIV/AIDS. Western blot is used to confirm the presence of HIV antibodies in a patient's blood after an initial positive ELISA test. Northern blotting is a technique used for RNA analysis, not for detecting HIV/AIDS (Choice A). Immunoblotting is another term for Western blotting, so Choice B is incorrect. Southern blotting is used for DNA analysis, not for detecting HIV/AIDS (Choice D).
2. How many arteries are there in an umbilical cord?
- A. Three
- B. One
- C. Two
- D. Four
Correct answer: C
Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.
3. Which one is not a barrier method for birth control?
- A. Diaphragms
- B. Cervical caps
- C. Vaults
- D. Intrauterine Devices (IUDs)
Correct answer: D
Rationale: The correct answer is D, Intrauterine Devices (IUDs). Barrier methods of birth control physically block sperm from reaching the egg. Diaphragms, cervical caps, and vaults are examples of barrier methods as they create a barrier that prevents sperm from reaching the cervix. In contrast, IUDs work by altering the cervical mucus and uterine lining, making it difficult for sperm to reach the egg, but they do not physically block sperm like barrier methods do.
4. What is dysmenorrhoea?
- A. Heavy menstruation
- B. Light menstruation
- C. Painful menstruation
- D. Infrequent menstruation
Correct answer: C
Rationale: Dysmenorrhoea is the medical term for painful menstruation. It is characterized by cramp-like abdominal pain that occurs just before or during menstruation. Choice A, heavy menstruation, is referred to as menorrhagia. Choice B, light menstruation, is not a term used to describe a specific menstrual condition. Choice D, infrequent menstruation, is known as oligomenorrhea, not dysmenorrhoea.
5. What is the role of relaxin hormone?
- A. Relaxation of the symphysis pubis.
- B. Stimulation of milk production.
- C. Stimulating the development of the nipple and duct system in the breast.
- D. None of the above.
Correct answer: A
Rationale: The correct answer is A: Relaxation of the symphysis pubis. Relaxin hormone is responsible for loosening the ligaments in the pelvic area, particularly the symphysis pubis, to prepare for childbirth. Choice B, stimulation of milk production, is incorrect as this is primarily regulated by prolactin. Choice C, stimulating the development of the nipple and duct system in the breast, is incorrect as this is mainly influenced by estrogen and progesterone during pregnancy. Therefore, the correct role of relaxin hormone is the relaxation of the symphysis pubis.
