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).

Which phase of the menstrual cycle is variable?
- A. Ovulatory
- B. Regenerative
- C. Secretory
- D. Menstrual
Correct Answer: B
Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.
What is a cord inserted to the very edge of the placenta known as?
- A. Battledore insertion
- B. Placenta velamentosa
- C. Placenta accreta
- D. Vasa Praevia
Correct Answer: A
Rationale: A cord inserted to the very edge of the placenta is known as battledore insertion. This occurs when the cord is attached to the fetal membranes at the placental margin rather than directly to the placental tissue. Placenta velamentosa refers to the condition where the umbilical cord inserts into the fetal membranes before it reaches the placenta. Placenta accreta is a condition where the placenta attaches too deeply into the uterine wall. Vasa Praevia is a condition where fetal blood vessels run across or near the internal cervical opening.
Which part of the female reproductive system remains blocked after tubectomy?
- A. Fallopian tube
- B. Cervix
- C. Uterine cavity
- D. None
Correct Answer: A
Rationale: After a tubectomy procedure, the Fallopian tube remains blocked. This is the correct answer because tubectomy involves the surgical blocking or sealing of the Fallopian tubes to prevent eggs from reaching the uterus, thus preventing pregnancy. Choice B, the cervix, is incorrect as it is not blocked during a tubectomy. Choice C, the uterine cavity, is also incorrect as the procedure does not involve blocking this part of the reproductive system. Choice D, none, is incorrect as the purpose of tubectomy is to block the Fallopian tubes.
Why is abortion important?
- A. It is easily conducted
- B. It can easily be diagnosed
- C. It causes serious complications such as infections and maternal death
- D. All of the above
Correct Answer: C
Rationale: Abortion is important due to the serious complications it can cause, such as infections and maternal death. Choices A and B are incorrect because ease of conducting or diagnosing abortion procedures does not inherently make abortion important. Choice D is incorrect because not all the options listed are reasons why abortion is important; only choice C highlights the critical aspect of potential complications.
What is one of the major issues affecting adolescents in terms of sexual and reproductive health?
- A. Limited access to contraceptives and family planning
- B. Equal representation in decision-making
- C. Decreased need for sexual education
- D. Equal opportunities for career growth
Correct Answer: A
Rationale: Limited access to contraceptives and family planning is indeed a major issue affecting adolescents in terms of sexual and reproductive health. This lack of access can lead to unintended pregnancies, sexually transmitted infections, and limited reproductive choices. Choice B, equal representation in decision-making, although important, is not directly related to sexual and reproductive health issues faced by adolescents. Choice C, decreased need for sexual education, is incorrect as proper sexual education is crucial in promoting healthy behaviors and preventing risks. Choice D, equal opportunities for career growth, is also unrelated to the specific issues surrounding sexual and reproductive health in adolescents.
