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. Abortion is defined as:

• A. Bleeding per vaginum in early pregnancy
• B. Willingness to terminate pregnancy
• C. Expulsion of products of conception after the 28th week of gestation
• D. Expulsion of products of conception before the 28th week of gestation

Correct answer: D

Rationale: Abortion is defined as the expulsion of products of conception before the 28th week of gestation. Choice A is incorrect as it describes bleeding in early pregnancy, not the definition of abortion. Choice B is incorrect as it refers to the willingness to terminate a pregnancy rather than the actual act of expulsion. Choice C is incorrect as it defines abortion as the expulsion of products of conception after the 28th week of gestation, which is considered a stillbirth.

4. Which of the following methods is used for permanent contraception in males?

• A. Vasectomy
• B. Tubal ligation
• C. Condoms
• D. Coitus interruptus

Correct answer: A

Rationale: The correct answer is A: Vasectomy. Vasectomy is a surgical procedure for permanent contraception in males by cutting or blocking the vas deferens. Choice B, Tubal ligation, is a method for permanent contraception in females by blocking or sealing the fallopian tubes. Choice C, Condoms, provide a barrier method of contraception but are not permanent. Choice D, Coitus interruptus, involves withdrawing the penis before ejaculation and is not a reliable method of contraception.

5. At 6-8 weeks of pregnancy, the breast changes include:

• A. Colostrum can be expressed.
• B. Breasts become tender.
• C. Montgomery's tubercles are prominent.
• D. Nipples become prominent and mobile.

Correct answer: C

Rationale: At 6-8 weeks of pregnancy, one of the changes in the breast includes the prominence of Montgomery's tubercles. These sebaceous glands around the nipple become more noticeable at this stage. Colostrum production usually occurs later in pregnancy, typically closer to the third trimester. While breast tenderness is a common symptom of early pregnancy, it is not specific to the 6-8 week timeframe. Nipples becoming more prominent and mobile may happen later in pregnancy as the body prepares for breastfeeding, but it is not a typical change seen specifically at 6-8 weeks.
