What is the function of progesterone support after embryo transfer in IVF?
- A. To stimulate egg growth during the next cycle.
- B. To maintain the uterine lining and support early pregnancy.
- C. To trigger ovulation during the current cycle.
- D. To prevent hormonal imbalances during stimulation.
Correct Answer: B
Rationale: The correct answer is B: To maintain the uterine lining and support early pregnancy. After embryo transfer in IVF, progesterone support is crucial to ensure the uterine lining remains thick and supportive for the implantation and early development of the embryo. Progesterone helps create a hospitable environment in the uterus for the embryo to implant and grow. It also supports the continued development of the pregnancy until the placenta can take over hormone production.
Choice A is incorrect because progesterone support after embryo transfer is not aimed at stimulating egg growth during the next cycle. Choice C is incorrect as progesterone support does not trigger ovulation during the current cycle; ovulation would have already been induced prior to embryo transfer. Choice D is incorrect as preventing hormonal imbalances during stimulation is not the primary function of progesterone support after embryo transfer.

A client has been notified that because of fallopian tube obstruction, her best option for becoming pregnant is through in vitro fertilization. The client asks the nurse about the procedure. Which of the following responses is correct?
- A. During the stimulation phase of the procedure
- B. the physician will make sure that only one egg reaches maturation.
- C. Preimplantation genetic diagnosis will be performed on your partner's sperm before they are mixed with your eggs.
- D. After ovarian stimulation
Correct Answer: D
Rationale: Extra embryos can be cryopreserved for future use.
What is the significance of a semen analysis in evaluating infertility?
- A. It determines the number, shape, and movement of sperm.
- B. It checks for genetic conditions affecting sperm.
- C. It monitors hormone levels in males.
- D. It identifies infections in the reproductive tract.
Correct Answer: A
Rationale: The correct answer is A because a semen analysis assesses important parameters such as sperm count, morphology (shape), and motility (movement), which are crucial factors in male fertility. Sperm count indicates the quantity of sperm available for fertilization. Morphology assesses the structural integrity of sperm, while motility determines their ability to reach and fertilize an egg. These parameters directly impact fertility potential.
Choice B is incorrect because a semen analysis does not specifically check for genetic conditions affecting sperm. Choice C is incorrect as hormone levels are not directly evaluated in a semen analysis. Choice D is incorrect because while infections can affect fertility, they are not the primary focus of a standard semen analysis.
A nurse is evaluating the effectiveness of preconception education. Which statement by the client indicates that additional education is needed?
- A. I know smoking is harmful in pregnancy, so I plan to quit soon. My husband has agreed to avoid smoking in my presence.
- B. I have started taking a daily prenatal vitamin with folic acid.
- C. My husband bought a small desk for his laptop computer.
- D. We plan to avoid the use of chemicals in our garden this year.
Correct Answer: C
Rationale: The correct answer is C because the statement about the husband buying a small desk for his laptop computer is irrelevant to preconception education. The focus of preconception education is on optimizing health before pregnancy, such as quitting smoking, taking prenatal vitamins, and avoiding harmful chemicals. The other choices (A, B, and D) all demonstrate an understanding of preconception health needs. Choice A shows awareness of the risks of smoking in pregnancy and a plan to quit. Choice B indicates the initiation of prenatal vitamin intake, particularly folic acid, which is crucial for preventing birth defects. Choice D highlights a proactive approach to environmental health by planning to avoid harmful chemicals in the garden.
A woman, who has undergone amniocentesis, has been notified that her baby is XX with a 14/21 robertsonian chromosomal translocation. The nurse helps the woman to understand which of the following?
- A. The baby will have a number of serious genetic defects.
- B. It is likely that the baby will be unable to have children when she grows up.
- C. Chromosomal translocations are common and rarely problematic.
- D. An abortion will probably be the best decision under the circumstances.
Correct Answer: C
Rationale: Robertsonian translocations are generally asymptomatic and not problematic.
A patient and her husband request to view the results of their infant's karyotype. An aneuploidy was noted. The nurse understands the results to indicate what?
- A. An abnormal number of chromosomes were present on the karyogram.
- B. Translocations were noted on some of the chromosomes.
- C. The infant's chromosomes had broken areas, causing an abnormality in the picture of the chromosomes.
- D. Some of the infant's chromosomes were duplicated to total 46 chromosomes.
Correct Answer: A
Rationale: Correct Answer: A
Rationale: A karyotype is a visual representation of an individual's chromosomes. An aneuploidy indicates an abnormal number of chromosomes, which can result in genetic disorders such as Down syndrome. A karyotype shows the number, size, and shape of chromosomes, so an abnormal number of chromosomes on the karyogram is the correct interpretation.
Summary of Other Choices:
B: Translocations involve the movement of genetic material between chromosomes, not an abnormal number of chromosomes.
C: Chromosomal breaks would not typically result in an aneuploidy but rather structural abnormalities.
D: Duplication of chromosomes to total 46 would not lead to aneuploidy but rather a normal chromosome count.
