HESI RN

Reproductive Health Exam

1. At 16 weeks of pregnancy, the breast changes include:

A. Montgomery's tubercles are prominent.
B. Darkening of the nipple.
C. Prickling, tingling sensation.
D. Colostrum can be expressed.

Correct answer: C

Rationale: At 16 weeks of pregnancy, the sensation of prickling and tingling in the breasts is common due to hormonal changes. Montgomery's tubercles becoming prominent is more characteristic of early pregnancy, typically around the first trimester. Darkening of the nipple, known as areola darkening, can occur but is more commonly observed later in pregnancy. The expression of colostrum, the first milk produced by the mammary glands, usually happens closer to the end of pregnancy or after childbirth, not typically at 16 weeks.

2. 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.

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. What is Dinoprostone commonly used for?

A. Cervical priming.
B. Pain management during labor.
C. Management of pre-term labor.
D. Management of post-partum hemorrhage.

Correct answer: C

Rationale: Dinoprostone is commonly used for the management of pre-term labor. While it can be used for cervical priming, its primary indication is for pre-term labor. Choice A is partially correct but not the most common use of Dinoprostone. Choices B and D are incorrect as Dinoprostone is not primarily used for pain management during labor or for the management of post-partum hemorrhage.

5. What is the function of luteinizing hormone?

A. Maintains the corpus luteum
B. Ripens the Graafian follicle
C. Prepares the breasts for lactation
D. Produces regrowth of the endometrium

Correct answer: A

Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.
