A couple is learning about assisted reproductive technologies (ART). Which method involves retrieving eggs and fertilizing them outside the body?
- A. Intrauterine insemination (IUI)
- B. In-vitro fertilization (IVF)
- C. Ovarian stimulation
- D. Egg freezing
Correct Answer: B
Rationale: The correct answer is B: In-vitro fertilization (IVF). In IVF, eggs are retrieved from the ovaries and fertilized with sperm in a laboratory dish. This method involves fertilization outside the body, making it the correct choice.
A: Intrauterine insemination (IUI) involves placing washed sperm directly into the uterus, not fertilizing eggs outside the body.
C: Ovarian stimulation is a process to stimulate the ovaries to produce multiple eggs but does not involve fertilization outside the body.
D: Egg freezing is a method where eggs are frozen for future use but does not involve fertilization outside the body.

A woman asks the nurse, 'My nuchal fold scan results were abnormal. What does that mean?' Which of the following comments is appropriate for the nurse to make at this time?
- A. I am sorry to tell you that your baby will be born with a serious deformity.
- B. The results show that your child will have cri du chat syndrome.
- C. The test is done to see if you are high risk for preterm labor.
- D. An abnormal test indicates that your baby may have Down syndrome.
Correct Answer: D
Rationale: Abnormal nuchal fold scans can indicate chromosomal abnormalities like Down syndrome.
What is the primary goal of using gonadotropins in fertility treatments?
- A. To suppress ovulation for egg preservation.
- B. To stimulate the ovaries to produce multiple eggs.
- C. To prevent hormonal fluctuations during the menstrual cycle.
- D. To enhance uterine lining growth for implantation.
Correct Answer: B
Rationale: The primary goal of using gonadotropins in fertility treatments is to stimulate the ovaries to produce multiple eggs. This increases the chances of successful fertilization and pregnancy. Gonadotropins mimic the natural hormones that regulate ovulation and stimulate the growth of follicles in the ovaries. By producing multiple eggs, there is a higher likelihood of at least one egg being successfully fertilized.
Choice A is incorrect because gonadotropins actually stimulate ovulation rather than suppress it.
Choice C is incorrect as gonadotropins do not prevent hormonal fluctuations but rather help regulate and induce controlled hormonal changes.
Choice D is incorrect as the primary goal of using gonadotropins is not to enhance uterine lining growth but rather to stimulate egg production in the ovaries.
Which instruction by the nurse should be included in the teaching plan for an infertile woman who has been shown to have a 28-day biphasic menstrual cycle?
- A. Douche with a cider vinegar solution immediately before having intercourse.
- B. Schedule intercourse every day from day 8 to day 14 of the menstrual cycle.
- C. Be placed on follicle-stimulating hormone therapy by the fertility specialist.
- D. Assess the basal body temperature pattern for at least 6 more months.
Correct Answer: B
Rationale: Intercourse during the fertile window (days 8–14 in a 28-day cycle) maximizes conception chances.
A nurse is counseling a couple on lifestyle modifications to improve fertility. Which recommendation is most appropriate?
- A. Increase caffeine intake for better energy.
- B. Maintain a healthy weight and avoid smoking.
- C. Engage in intensive daily exercise.
- D. Focus solely on timing of intercourse.
Correct Answer: B
Rationale: The correct answer is B: Maintain a healthy weight and avoid smoking. This recommendation is most appropriate because both factors significantly impact fertility. Being at a healthy weight improves hormonal balance and ovulation, while smoking can harm sperm quality and reduce fertility.
Explanation for why other choices are incorrect:
A: Increasing caffeine intake may negatively affect fertility, as high levels of caffeine have been linked to reduced fertility in both men and women.
C: Engaging in intensive daily exercise can actually disrupt menstrual cycles and ovulation, negatively impacting fertility.
D: Focusing solely on timing of intercourse overlooks the importance of overall lifestyle factors that can affect fertility, such as diet, weight, and smoking.
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.
