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. Which of the following is included in a gynecological examination?

A. Abdominal examination
B. General and systemic examination
C. Obstetric exam
D. Pelvic examination

Correct answer: A

Rationale: Correct! A gynecological examination typically includes an abdominal examination to assess the overall health of the patient. This includes checking for any abnormalities, tenderness, or masses. General and systemic examinations are also important as they provide valuable information about the patient's overall health status. Pelvic examination is another essential component of a gynecological exam to assess the reproductive organs. Obstetric exams, focusing on pregnant women, are not part of routine gynecological examinations.

3. What lines the uterus?

A. Endometrium.
B. Myometrium.
C. Perimetrium.
D. Glandular tissue.

Correct answer: A

Rationale: The correct answer is A, Endometrium. The endometrium is the inner lining of the uterus where the fertilized egg implants and develops during pregnancy. Myometrium (Choice B) is the middle layer of the uterus consisting of muscle tissue. Perimetrium (Choice C) is the outer layer of the uterus. Glandular tissue (Choice D) is a broad term referring to tissue containing glands, but it does not specifically line the uterus.

4. 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.

5. Which of the following is the most effective method of contraception?

A. Barrier methods
B. Hormonal pills
C. Intrauterine devices (IUDs)
D. Sterilization

Correct answer: D

Rationale: Sterilization is considered the most effective method of contraception because it permanently prevents pregnancy. Barrier methods, hormonal pills, and IUDs are highly effective as well, but they are reversible methods and may have a higher failure rate compared to sterilization.
