The female reproductive system includes the following structures:
- A. ovary;
- B. Fallopian tubes;
- C. vagina;
- D. vulva;
Correct Answer: A
Rationale: The correct answer is A: ovary. The female reproductive system includes the ovaries, which are responsible for producing eggs and hormones like estrogen and progesterone. The Fallopian tubes are passageways for eggs to travel from the ovaries to the uterus, not a part of the system itself. The vagina is the birth canal and where sperm enters during intercourse, but it is not a reproductive organ. The vulva includes external genitalia like the labia and clitoris, but it is not a reproductive structure. Therefore, the ovary is the only structure directly involved in the reproductive process.

During the latter stages of pregnancy, many women experience an increase in body hair growth in a masculine pattern. What is the explanation for this?
- A. The ovaries secrete some testosterone along with the large amounts of estrogen produced late in pregnancy
- B. The fetal ovaries and testes secrete androgenic steroids
- C. The maternal and fetal adrenal glands secrete large amounts of androgenic steroids that are used by the placenta to form estrogen
- D. The placenta secretes large amounts of estrogen, some of which is metabolized to testosterone
Correct Answer: C
Rationale: Step 1: Maternal and fetal adrenal glands secrete androgenic steroids.
Step 2: Placenta uses these androgenic steroids to form estrogen.
Step 3: Increased estrogen levels can lead to body hair growth.
Therefore, the correct answer (C) is supported by the process of androgenic steroids being secreted by the adrenal glands, utilized by the placenta to form estrogen, resulting in increased body hair growth.
Summary:
A (The ovaries secrete some testosterone along with estrogen) is incorrect as testosterone is not primarily secreted by the ovaries late in pregnancy.
B (The fetal ovaries and testes secrete androgenic steroids) is incorrect as the primary source of androgenic steroids in this context is the adrenal glands, not fetal ovaries or testes.
D (The placenta secretes estrogen, some of which is metabolized to testosterone) is incorrect as the main source of estrogen in this scenario is from the and
The superior portion of the uterus is the _____.
- A. body
- B. cervix
- C. fundus
- D. infundibulum
Correct Answer: C
Rationale: The correct answer is C: fundus. The fundus is the superior portion of the uterus, located above the entry point of the fallopian tubes. It is the part of the uterus where the fertilized egg implants and grows during pregnancy. The body of the uterus (choice A) is the main central portion, the cervix (choice B) is the lower narrow part that connects to the vagina, and the infundibulum (choice D) is a part of the fallopian tube, not the uterus. Thus, the fundus is the correct choice as it specifically refers to the superior portion of the uterus.
We can state the following about the uterus:
- A. it is made up of corpus and cervix;
- B. the vagina is inserted on the cervix;
- C. the uterine cavity displays a mucous membrane that undergoes cyclical modifications;
- D. it has striated musculature, with longitudinal, radial and circular fibers;
Correct Answer: C
Rationale: Step 1: The uterine cavity displays a mucous membrane that undergoes cyclical modifications due to hormonal changes during the menstrual cycle.
Step 2: This mucous membrane is essential for embryo implantation and plays a crucial role in pregnancy.
Step 3: The cyclical modifications of the mucous membrane are necessary for the shedding of the endometrium during menstruation.
Summary: Choice C is correct because it accurately describes a key function of the uterus related to the menstrual cycle. Choices A, B, and D are incorrect as they do not address the specific function of the uterine cavity and its mucous membrane modifications.
Estrogen is required for normal reproductive function in the male. Where is the principal site of estrogen synthesis in the male?
- A. Leydig cells
- B. Osteoblasts
- C. Liver cells
- D. Prostate cells
Correct Answer: C
Rationale: Rationale:
1. The correct answer is C: Liver cells. The liver is the principal site of estrogen synthesis in the male.
2. Liver cells contain the enzyme aromatase, which converts androgens into estrogens.
3. Estrogen plays a crucial role in maintaining normal reproductive function in males.
4. Leydig cells (Choice A) are responsible for testosterone production, not estrogen synthesis.
5. Osteoblasts (Choice B) are bone cells involved in bone formation, not estrogen synthesis.
6. Prostate cells (Choice D) are involved in prostate function, not estrogen synthesis.
A 24-yr-old woman says she wants to begin using oral contraceptives. Which information from the nursing assessment is important to report to the health care provider before a prescription is considered?
- A. The patient quit smoking 5 months previously.
- B. The patient’s blood pressure is 150/86 mm Hg.
- C. The patient has not been vaccinated for rubella
- D. The patient has chronic iron-deficiency anemia
Correct Answer: B
Rationale: Step 1: Elevated blood pressure (BP) is a contraindication for oral contraceptives due to increased risk of cardiovascular events.
Step 2: BP of 150/86 mm Hg falls in the hypertensive range.
Step 3: Reporting high BP to the healthcare provider is crucial for assessing the patient's cardiovascular risk.
Step 4: Other choices are not immediate contraindications for oral contraceptives: A - Smoking cessation is a positive factor, C - Rubella vaccination can be addressed separately, D - Iron-deficiency anemia can be managed alongside oral contraceptives.
