which technique is used to detect aids

HESI RN

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. At 8-12 weeks of pregnancy, the breast changes include:

A. Prickling, tingling sensation.
B. Nipples become prominent and mobile.
C. Darkening of the nipple.
D. Breast start producing milk

Correct answer: D

Rationale: At 8-12 weeks of pregnancy, the breast changes typically include the onset of colostrum production, not just tenderness. Colostrum is the first milk produced by the mammary glands during pregnancy. While some women may experience prickling or tingling sensations, prominent and mobile nipples, and darkening of the nipple, the key change during this time period is the production of colostrum. This substance is rich in antibodies and important for the newborn's initial nutrition. Therefore, the correct answer is not listed among the choices provided.

3. By which name is family planning currently known?

A. Reproductive and child care
B. Family and child care
C. Reproductive and child health
D. Reproductive and child health care

Correct answer: C

Rationale: Family planning is currently known as Reproductive and Child Health (RCH). It encompasses a broader scope beyond just care, focusing on the overall health aspects related to reproduction and child well-being. Choices A, B, and D are incorrect as they do not accurately reflect the comprehensive nature of family planning under the term Reproductive and Child Health.

4. Which statement accurately describes the female pelvis?

A. Gynaecoid pelvis has a wedge-shaped inlet
B. Platypelloid pelvis has an oval inlet
C. Anthropoid pelvis has a long narrow oval inlet
D. Android pelvis is wedge-shaped

Correct answer: B

Rationale: The correct answer is B because the Platypelloid pelvis indeed has an oval inlet. Gynaecoid pelvis, not mentioned in the choices, has a round inlet. Anthropoid pelvis has a long, narrow oval inlet, which makes choice C incorrect. Choice D is incorrect as the Android pelvis is actually heart-shaped with a narrowed inlet.

5. How does human sperm move?

A. Flagella
B. Cilia
C. Neutrophils
D. None of the above

Correct answer: A

Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.
