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. What is amniocentesis used to detect?

• A. Sexually transmitted diseases
• B. Presence of certain genetic disorders
• C. Causes of infertility
• D. Presence of pneumonia germs

Correct answer: B

Rationale: Amniocentesis is a prenatal test used to detect certain genetic disorders in a developing fetus. It involves collecting a small sample of the amniotic fluid surrounding the fetus and analyzing the genetic material present in the cells. This test is not used to detect sexually transmitted diseases, causes of infertility, or the presence of pneumonia germs. Therefore, the correct answer is B.

3. 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.

4. The structures of the vulva lie ____________ to the vagina.

• A. Posterior
• B. Inferior
• C. Lateral
• D. Superior

Correct answer: B

Rationale: The correct answer is 'Inferior.' The structures of the vulva are positioned below the vagina, making them inferior. Choice A, 'Posterior,' refers to structures located at the back, not below the vagina. Choice C, 'Lateral,' means to the side, which is not the correct orientation in this context. Choice D, 'Superior,' indicates above, which is the opposite of the correct relationship described in the question.

5. What is the inner lining of the non-pregnant uterus called?

• A. Decidua
• B. Myometrium
• C. Endometrium
• D. Sponge layer

Correct answer: C

Rationale: The correct answer is C, Endometrium. The endometrium is the inner lining of the non-pregnant uterus that undergoes cyclic changes in response to hormonal fluctuations during the menstrual cycle. Choice A, Decidua, is the specialized membrane formed during pregnancy. Choice B, Myometrium, refers to the middle layer of the uterine wall composed of smooth muscle. Choice D, Sponge layer, is not a term used to describe the inner lining of the uterus.
