What phase corresponds with the luteal phase?
- A. Menstrual phase
- B. Follicular phase
- C. Secretory phase
- D. Menstrual phase
Correct Answer: C
Rationale: The luteal phase corresponds with the secretory phase. During the menstrual cycle, the luteal phase follows ovulation and is characterized by the development of the corpus luteum, secreting progesterone to prepare the endometrium for a potential pregnancy. The other choices, menstrual phase (A), follicular phase (B), and the repeated choice of menstrual phase (D) do not align with the luteal phase and its functions.

Legislation allowing nursing staff to provide contraceptives has resulted in all of the following EXCEPT:
- A. More nursing staff have been trained to provide family planning services
- B. Many population and family planning organizations have emerged
- C. Enhanced implementation of population and family planning programs
- D. Male involvement in family planning services
Correct Answer: D
Rationale: The correct answer is D. Male involvement in family planning services has not significantly resulted from legislation allowing nursing staff to provide contraceptives. While legislation has led to more nursing staff being trained, the emergence of population and family planning organizations, and enhanced implementation of programs, it has not directly impacted male involvement in family planning.
What is one role of the hormone estrogen?
- A. Stimulates the development of the milk-producing tissue.
- B. Stimulates the production of lactoferrin.
- C. Stimulates the development of the nipple and duct system in the breast.
- D. Stimulates the secretion of relaxin.
Correct Answer: A
Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.
Which of the following is not a complication of menopause?
- A. Fractures
- B. Alzheimer's disease
- C. Congestive heart failure
- D. Painful intercourse
Correct Answer: C
Rationale: Congestive heart failure is not typically associated with menopause. Menopause is linked to an increased risk of fractures due to bone density loss, a higher risk of Alzheimer's disease due to hormonal changes, and painful intercourse due to vaginal dryness and thinning of tissues. While cardiovascular health can be affected by menopause, congestive heart failure is not a direct complication associated with menopause.
A solid ball of 12-16 cells having undergone mitotic division after fertilization is:
- A. Zygote
- B. Blastomere
- C. Morula
- D. Blastocyst
Correct Answer: C
Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'
Amniocentesis, a prenatal diagnostic test used to determine fetal sex, genetic anomalies, and biochemical abnormalities, is based on:
- A. The karyotyping of the amniotic fluid
- B. Chorionic villus sampling
- C. Umbilical cord blood sampling
- D. Ultrasound
Correct Answer: A
Rationale: The correct answer is A. Amniocentesis involves the analysis of the fetal cells present in the amniotic fluid, which is extracted from the amniotic sac surrounding the developing fetus. This fluid contains cells shed by the fetus, which can be cultured and analyzed to obtain a karyotype, providing information about the fetal sex, genetic anomalies, and biochemical abnormalities. Choices B, C, and D are incorrect because chorionic villus sampling involves obtaining a sample of the chorionic villi from the placenta, not the amniotic fluid; umbilical cord blood sampling is typically used for other purposes like assessing the baby's blood for infections or genetic disorders; and ultrasound is a diagnostic imaging technique that does not involve the analysis of fetal cells for genetic information.
