The procedure in which ova are removed by laparoscopy, mixed with sperm, and the embryo(s) returned to the woman's uterus is
- A. in vitro fertilization (IVF).
- B. tubal embryo transfer (TET).
- C. therapeutic insemination (IUI).
- D. gamete intrafallopian transfer (GIFT).
Correct Answer: A
Rationale: The correct answer is A: in vitro fertilization (IVF). In IVF, ova are retrieved via laparoscopy, fertilized with sperm in a lab dish, and then the resulting embryo(s) are transferred back to the woman's uterus. This process allows for fertilization to occur outside the body.
Incorrect choices:
B: Tubal embryo transfer (TET) involves transferring embryos directly into the fallopian tubes, not the uterus.
C: Therapeutic insemination (IUI) is the process of injecting sperm directly into the uterus, not involving the removal and fertilization of ova.
D: Gamete intrafallopian transfer (GIFT) involves transferring both eggs and sperm into the fallopian tubes for fertilization to occur internally, not in a lab dish.

Nurses working in a midwifery office have attended a conference to learn about factors that increase a woman's risk of becoming infertile. To evaluate the nurses' learning, the conference coordinator tested the nurses' knowledge at the conclusion of the seminar. Which of the following problems should the nurses state increase a client's risk of developing infertility problems? Select all that apply.
- A. Women who have menstrual cycles that are up to 30 days long.
- B. Women who experience pain during intercourse.
- C. Women who have had pelvic inflammatory disease.
- D. Women who have excess facial hair.
Correct Answer: B
Rationale: Pain during intercourse, pelvic inflammatory disease, and hirsutism (excess facial hair) are associated with infertility.
The nurse is analyzing the pedigree shown below. How should the nurse interpret the genotype of the individual in location II-4?

A nurse is offering preconception counseling in a primary care clinic. Which statement by a patient indicates a need for correction?
- A. Pregnancy rates are not related to the age of the male partner.
- B. Sexually active males should be routinely tested for STIs and treated appropriately.
- C. Maintaining a healthy weight is important for the reproductive health of both female and male partners.
- D. Certain medications, such as testosterone supplementation and chemotherapy, can impact male fertility.
Correct Answer: A
Rationale: The correct answer is A. Pregnancy rates are indeed related to the age of the male partner because sperm quality and quantity decline with age. This is crucial information in preconception counseling. Choice B is correct as STI testing for sexually active males is important for reproductive health. Choice C is correct as maintaining a healthy weight is crucial for both partners' fertility. Choice D is correct as certain medications can impact male fertility. In summary, the incorrect choice (A) contradicts established knowledge about male age and fertility, making it the correct answer.
A patient asks about the benefits of time-lapse embryo monitoring in IVF. What should the nurse highlight?
- A. It guarantees successful implantation of embryos.
- B. It allows continuous observation of embryo development without disturbing the culture environment.
- C. It eliminates the need for hormone support during IVF.
- D. It shortens the time required for fertilization.
Correct Answer: B
Rationale: The correct answer is B because time-lapse embryo monitoring in IVF allows continuous observation of embryo development without disturbing the culture environment. This is crucial as it provides real-time data on embryo growth and helps in selecting the healthiest embryos for transfer. Choice A is incorrect as implantation success is not guaranteed by monitoring alone. Choice C is incorrect as hormone support is still needed in IVF. Choice D is incorrect as time-lapse monitoring does not affect the fertilization process itself.
What is the significance of cervical mucus changes during the menstrual cycle?
- A. Cervical mucus changes confirm pregnancy.
- B. It becomes clear and stretchy during ovulation, indicating peak fertility.
- C. Cervical mucus changes have no relevance to fertility.
- D. It only occurs after ovulation and signals the end of fertility.
Correct Answer: B
Rationale: The correct answer is B: It becomes clear and stretchy during ovulation, indicating peak fertility. Cervical mucus changes during the menstrual cycle are important as they reflect the hormonal changes that occur. During ovulation, cervical mucus becomes clear, watery, and stretchy, resembling egg whites. This type of mucus promotes sperm survival and motility, indicating the most fertile period for conception. The other choices are incorrect because cervical mucus changes do not confirm pregnancy (A), are indeed relevant to fertility (C), and do not only occur after ovulation but actually signal peak fertility during ovulation (D).
