A couple is considering ICSI (Intracytoplasmic Sperm Injection) as part of IVF. What should the nurse explain?
- A. ICSI is only used for couples with unexplained infertility.
- B. ICSI involves injecting a single sperm directly into an egg.
- C. ICSI guarantees fertilization and successful pregnancy.
- D. ICSI eliminates the need for ovarian stimulation.
Correct Answer: B
Rationale: The correct answer is B because ICSI involves injecting a single sperm directly into an egg to facilitate fertilization. This method is used when there are issues with sperm quality or quantity. It is not limited to couples with unexplained infertility (choice A), does not guarantee successful pregnancy (choice C), and does not eliminate the need for ovarian stimulation (choice D). Therefore, choice B is the most accurate explanation of what ICSI entails.

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.
Which situation best describes secondary infertility in a couple?
- A. Never conceived.
- B. Had repeated spontaneous abortions.
- C. Not conceived after 1 year of unprotected intercourse.
- D. Has one child but cannot conceive a second time.
Correct Answer: D
Rationale: The correct answer is D because secondary infertility refers to the inability of a couple to conceive after having one or more children without any fertility issues. This situation indicates that the couple had a successful pregnancy in the past but is now facing difficulties conceiving again.
A, B, and C are incorrect:
A: Never conceived - This does not align with the definition of secondary infertility as it involves a previous successful pregnancy.
B: Had repeated spontaneous abortions - This refers to recurrent pregnancy loss, not secondary infertility.
C: Not conceived after 1 year of unprotected intercourse - This describes primary infertility, not secondary infertility.
A client is to have a hysterosalpingogram. In this procedure, the physician will be able to determine which of the following?
- A. Whether or not the ovaries are maturing properly.
- B. If the endometrium is fully vascularized.
- C. If the cervix is incompetent.
- D. Whether or not the fallopian tubes are obstructed.
Correct Answer: D
Rationale: A hysterosalpingogram uses contrast dye to visualize the fallopian tubes and uterus, identifying obstructions.
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.
