A patient undergoing IVF asks about blastocyst transfer. What is the nurse's best explanation?
- A. Blastocyst transfer occurs on the day of egg retrieval.
- B. It involves transferring embryos that have developed for 5 to 6 days.
- C. Blastocyst transfer guarantees pregnancy success.
- D. It is performed only when natural conception has failed.
Correct Answer: B
Rationale: The correct answer is B because blastocyst transfer typically occurs on day 5 or 6 after fertilization when the embryo has reached a more advanced stage of development. This increases the likelihood of successful implantation in the uterus. Choice A is incorrect because it does not align with the typical timeline of blastocyst transfer. Choice C is incorrect as pregnancy success is not guaranteed with blastocyst transfer, though it may improve the chances. Choice D is incorrect as blastocyst transfer is a standard procedure in IVF and not limited to cases where natural conception has failed.

At her first prenatal visit, a woman relates that her maternal aunt has cystic fibrosis (CF), an autosomal recessive illness. Which of the following comments is appropriate for the nurse to make at this time?
- A. We can check to see whether or not you are a carrier for cystic fibrosis.
- B. It is unnecessary for you to worry since your aunt is not a direct relation.
- C. You should have an amniocentesis to see whether or not your child has the disease.
- D. Please ask your mother whether she has ever had any symptoms of cystic fibrosis.
Correct Answer: A
Rationale: Carrier testing can determine if the woman carries the CF gene.
What is the significance of a hysteroscopy in infertility evaluation?
- A. To measure hormone levels in the uterus.
- B. To visualize and treat abnormalities within the uterine cavity.
- C. To monitor egg development during ovulation induction.
- D. To assess ovarian reserve through imaging.
Correct Answer: B
Rationale: The correct answer is B: To visualize and treat abnormalities within the uterine cavity. A hysteroscopy is a minimally invasive procedure that allows direct visualization of the inside of the uterus using a thin, lighted tube. In infertility evaluation, it helps identify and treat issues such as polyps, fibroids, adhesions, or other abnormalities that may be interfering with implantation or causing recurrent miscarriages. It is crucial for improving fertility outcomes.
Choice A is incorrect because a hysteroscopy does not measure hormone levels in the uterus. Choice C is incorrect because monitoring egg development is typically done through ultrasound imaging, not hysteroscopy. Choice D is incorrect because assessing ovarian reserve is usually done through blood tests and ultrasound evaluation of the ovaries, not hysteroscopy.
Which type of breech presentation is identified when the buttocks present first, with both legs extended up toward the face?
- B. A. frank
- C. B. full
- D. C. complete
Correct Answer: A
Rationale: In a frank breech presentation, the buttocks present first, with both legs extended up toward the face. This is a common breech presentation that requires careful monitoring during labor and birth to ensure a safe delivery. In a full or complete breech, the fetus sits cross-legged above the cervix, while in a footling breech, one or both legs are presenting. Understanding the different types of breech presentations is crucial for providing appropriate care and support during labor and birth.
During preconception counseling, a nurse discusses the impact of male age on fertility. What statement requires 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 because male age does impact fertility. Advanced paternal age is associated with decreased fertility and increased risk of genetic abnormalities in offspring. Choice B is correct as STIs can affect fertility. Choice C is relevant as obesity can impact male fertility. Choice D is correct as certain medications can impact male fertility. Overall, choice A is incorrect as male age does play a role in fertility outcomes.
A provider has ordered several diagnostic procedures for a couple with suspected infertility. Which diagnostic procedure is useful for determining if ovulation has occurred?
- A. FSH level
- B. Progesterone level
- C. Estrogen level
- D. Vaginal ultrasound
Correct Answer: B
Rationale: The correct answer is B: Progesterone level. Progesterone is the hormone secreted after ovulation, indicating that ovulation has occurred. Monitoring progesterone levels can confirm ovulation. FSH (A) and estrogen (C) levels reflect the ovarian function but do not directly confirm ovulation. Vaginal ultrasound (D) can visualize the ovaries but does not definitively confirm ovulation.
