Sample Questions

1.
What hormone stimulates the release of the follicle-stimulating hormone (FSH) from both male and female glands?
A)
Growth hormone-releasing hormone (GHRH)
B)
Thyrotropin-releasing hormone (TRH)
C)
Gonadotropin-releasing hormone (GnRH)
D)
Prolactin-releasing hormone (PRH)
Ans:
C

Feedback:

The male and female glands respond to luteinizing hormone (LH) and FSH, which are released from the anterior pituitary in response to stimulation from GnRH that is released from the hypothalamus. GHRH stimulates the release of the growth hormone, which targets cell growth. TRH stimulates the thyroid-stimulating hormone, which targets the thyroid gland. PRH stimulates the release of prolactin, which is necessary for milk production.

2.
A nurse is providing patient education to a patient as part of her work in a fertility clinic. The nurse explains possible reasons for infertility. When explaining how the ovaries are involved in conception, what will the nurse stress?
A)
Ova quickly degenerate and most are absorbed in the body before the age of 12.
B)
The ovaries at birth contain all of the ova that a woman will have.
C)
Ova aggregate, causing millions to be contained in a storage site called a follicle.
D)
Follicles produce only estrogen; the uterus produces progesterone.
Ans:
B

Feedback:

It would be important to explain that the woman’s ova do not increase or decrease from birth to childbearing years. The nurse will stress that all the ova that a woman will have will be present at birth. The patient should understand that if she does not ovulate 1 month or for several months, it is not because she has done something to her body to cause this. Ova slowly degenerate over a lifetime or they are released once a month until menopause is complete. Each ovum is contained in a storage site called a follicle, which produces the female sex hormones, estrogen and progesterone.

3.
The nursing instructor is discussing the physiology of pregnancy with her clinical group. What hormone, produced during pregnancy, would the instructor tell the students helps to maintain the pregnancy until birth of the fetus? Options A, B, and C are not correct.
A)
High levels of estrogen only
B)
High levels of estrogen, low levels of progesterone
C)
Low levels of estrogen, high levels of progesterone
D)
High levels of estrogen and progesterone
Ans:
D

Feedback:

In a pregnant woman, both estrogen and progesterone hormones have specific functions. High levels of both hormones are needed for the maintenance of pregnancy.

4.
The nursing instructor is talking with her class of students about the female reproductive system. A student is trying to understand the role of progesterone in the body. What nonreproductive affect does progesterone have on the body?
A)
Decreased body temperature
B)
Decreased appetite
C)
Anti-insulin
D)
Increased uterine motility
Ans:
C

Feedback:

Progesterone has an anti-insulin effect to generate a higher blood glucose concentration to allow for rapid diffusion of glucose to the developing embryo. Body temperature and appetite are increased by progesterone. Uterine motility is decreased to provide increased chance that implantation can occur.

5.
What hormone causes ovulation to occur?
A)
Adrenocorticotropic hormone (ACTH)
B)
Luteinizing hormone (LH)
C)
Prolactin
D)
Follicle-stimulating hormone (FSH)
Ans:
B

Feedback:

When the circulating estrogen level rises high enough, it stimulates a massive release of LH from the anterior pituitary causing one of the developing follicles to burst and release the ovum with its stored hormones into the system. ACTH targets the adrenal corticosteroid hormone, which helps prepare the body for the “fight or flight” response. Prolactin is responsible for milk production and FSH in combination with LH stimulate follicles on the outer surface of the uterus to grow and develop and also stimulates the release of estrogen and progesterone.
