A patient undergoing IVF asks about the role of gonadotropins. What should the nurse explain?
- A. Gonadotropins suppress ovulation to control the cycle.
- B. They stimulate the ovaries to produce multiple eggs for retrieval.
- C. They are only used during natural conception cycles.
- D. Gonadotropins replace progesterone in early pregnancy.
Correct Answer: B
Rationale: The correct answer is B because gonadotropins stimulate the ovaries to produce multiple eggs for retrieval during IVF. This is crucial to increase the chances of successful fertilization. Choice A is incorrect as gonadotropins actually stimulate ovulation. Choice C is incorrect as gonadotropins are specifically used in assisted reproductive technologies like IVF. Choice D is incorrect as gonadotropins do not replace progesterone but rather help in follicular development.

A nurse is providing care to a pregnant woman in labor. The woman is in the first stage of labor. When describing this stage to the client, which event would the nurse identify as the major change occurring during this stage?
- A. regular contractions
- B. cervical dilation
- C. fetal movement through the birth canal
- D. placental separation
Correct Answer: B
Rationale: The primary change during the first stage of labor is cervical dilation. Contractions occur during both the first and second stages, fetal movement through the birth canal is a major change in the second stage, and placental separation occurs in the third stage.
During infertility counseling, the nurse explains the purpose of an HSG (hysterosalpingogram). What is the best explanation?
- A. It evaluates ovarian function and hormone levels.
- B. It assesses the structure and patency of the uterus and fallopian tubes.
- C. It determines the timing of ovulation for insemination.
- D. It monitors fetal development during early pregnancy.
Correct Answer: B
Rationale: Rationale: The correct answer is B because an HSG is used to visualize the structure and patency of the uterus and fallopian tubes, helping to diagnose causes of infertility such as tubal blockages or abnormalities. A is incorrect because HSG does not assess ovarian function or hormone levels. C is incorrect as HSG does not determine ovulation timing but rather evaluates tubal patency. D is incorrect because HSG is not used to monitor fetal development.
The nurse in a genetic clinic interviews a couple and develops a pedigree chart. Which inheritance patterns does the pedigree chart portray?
- A. Autosomal recessive
- B. X-linked recessive
- C. Autosomal dominant
- D. X-linked dominant
Correct Answer: C
Rationale: The correct answer is C, Autosomal dominant. In an autosomal dominant inheritance pattern, the trait is passed down from generation to generation, affecting both males and females equally. This is indicated by the presence of the trait in every generation of the pedigree chart. In contrast, autosomal recessive traits would skip generations and require both parents to be carriers. X-linked recessive traits mainly affect males and skip generations. X-linked dominant traits would be present in every generation but would affect more females than males.
A nurse is educating a patient about frozen embryo transfer (FET). What should be emphasized?
- A. FET requires daily hormone injections for success.
- B. FET involves transferring previously frozen embryos into the uterus.
- C. FET is only performed if natural conception is impossible.
- D. FET guarantees a successful pregnancy outcome.
Correct Answer: B
Rationale: The correct answer is B: FET involves transferring previously frozen embryos into the uterus. This is because FET is a process where frozen embryos from a previous IVF cycle are thawed and transferred into the uterus. The other choices are incorrect: A is false as hormone injections may not be required daily, C is false as FET can be done for various reasons beyond just natural conception issues, and D is false as success is not guaranteed in any fertility treatment.
During IVF, a patient asks about the role of estrogen in preparing for embryo transfer. What should the nurse explain?
- A. Estrogen helps regulate ovarian stimulation protocols.
- B. Estrogen thickens the uterine lining, creating a supportive environment for implantation.
- C. Estrogen prevents premature ovulation during stimulation cycles.
- D. Estrogen eliminates the need for progesterone support post-transfer.
Correct Answer: B
Rationale: The correct answer is B because estrogen plays a crucial role in thickening the uterine lining, creating a supportive environment for embryo implantation during IVF. This is essential for successful pregnancy. Estrogen does not directly regulate ovarian stimulation protocols (choice A), prevent premature ovulation (choice C), or eliminate the need for progesterone support post-transfer (choice D). Estrogen primarily focuses on preparing the uterus for implantation rather than affecting other aspects of the IVF process.
