- A. Amniocentesis.
- B. Chorionic villus sampling.
- C. Pre-implantation genetic diagnosis.
- D. Gamete intrafallopian transfer.
Correct Answer: C
Rationale: Pre-implantation genetic diagnosis allows screening of embryos before implantation.

The nurse is educating a client about hysterosalpingograms. Which information should the nurse include prior to this procedure?
- A. This procedure is always performed under general anesthesia.
- B. This procedure should be performed after ovulation has occurred.
- C. This procedure involves instillation of a radiopaque dye into the uterine cavity.
- D. After the procedure, the client should take Tylenol to decrease cramping.
Correct Answer: C
Rationale: Rationale for Correct Answer C:
1. Hysterosalpingogram (HSG) involves instillation of a radiopaque dye into the uterine cavity to visualize the uterus and fallopian tubes.
2. This dye helps to identify any abnormalities or blockages in the reproductive system.
3. The nurse should include this information as it is essential for the client to understand the purpose and process of the procedure.
4. Understanding the use of the dye can help alleviate any anxiety or concerns the client may have.
Summary of Incorrect Choices:
A: This procedure is typically performed without general anesthesia.
B: HSG can be performed at various points in the menstrual cycle, not specifically after ovulation.
D: Tylenol may be recommended for pain relief post-procedure, but it is not a necessary pre-procedure step.
During an infertility consultation, the nurse explains the impact of endometriosis on fertility. What should the nurse emphasize?
- A. Endometriosis improves the chances of conception naturally.
- B. Endometriosis can cause scarring and reduce ovarian function.
- C. Endometriosis is unrelated to infertility.
- D. Endometriosis eliminates the need for fertility treatments.
Correct Answer: B
Rationale: The correct answer is B because endometriosis can lead to scarring in the reproductive organs and reduce ovarian function, affecting fertility. Scarring can block the fallopian tubes, impairing egg and sperm transport. Reduced ovarian function can affect egg quality and quantity. Choices A, C, and D are incorrect. Endometriosis does not improve natural conception chances; it is a leading cause of infertility. It is related to infertility due to its impact on reproductive organs. Endometriosis often necessitates fertility treatments due to its effects on fertility.
A couple undergoing IVF asks about the risk of multiple pregnancies. What should the nurse discuss?
- A. Transferring multiple embryos increases the risk of multiples, which can lead to complications.
- B. Single embryo transfers always result in twins or higher multiples.
- C. Multiple pregnancies have no impact on maternal or fetal health.
- D. The number of embryos transferred does not affect pregnancy outcomes.
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. Transferring multiple embryos increases the chance of multiple pregnancies, which can lead to complications such as preterm birth and low birth weight.
2. This is an important consideration for the couple undergoing IVF to understand the potential risks involved.
3. Single embryo transfers reduce the risk of multiples and associated complications.
4. Choices B, C, and D are incorrect as they provide inaccurate information that contradicts the known risks associated with multiple pregnancies.
What is the purpose of progesterone in supporting early pregnancy?
- A. To increase fetal growth rates.
- B. To maintain the uterine lining and prevent menstrual shedding.
- C. To stimulate ovulation during the menstrual cycle.
- D. To regulate the release of other reproductive hormones.
Correct Answer: B
Rationale: The correct answer is B because progesterone plays a crucial role in maintaining the uterine lining to support implantation and prevent menstrual shedding. Progesterone prepares the uterus for the potential implantation of a fertilized egg by thickening the endometrium. If fertilization occurs, progesterone continues to support the pregnancy by ensuring the uterine lining remains intact to provide a nurturing environment for the developing embryo. Choices A, C, and D are incorrect because progesterone's main function in early pregnancy is not to increase fetal growth rates, stimulate ovulation, or regulate the release of other reproductive hormones.
What is the role of pelvic ultrasound in infertility evaluation?
- A. To evaluate ovarian reserve directly.
- B. To visualize uterine and ovarian structures.
- C. To measure hormone levels in the bloodstream.
- D. To identify genetic abnormalities in embryos.
Correct Answer: B
Rationale: The correct answer is B, as pelvic ultrasound allows visualization of uterine and ovarian structures. This is essential in assessing conditions like fibroids, polyps, ovarian cysts, and structural abnormalities that may affect fertility. Ovarian reserve evaluation (A) involves separate tests like AMH levels. Hormone levels (C) are typically measured through blood tests. Genetic abnormalities in embryos (D) are usually identified through preimplantation genetic testing, not pelvic ultrasound.
