What is the role of luteinizing hormone (LH) in the menstrual cycle?
- A. To maintain the uterine lining after ovulation.
- B. To stimulate the release of an egg from the ovary.
- C. To regulate progesterone production during pregnancy.
- D. To inhibit follicle-stimulating hormone (FSH).
Correct Answer: B
Rationale: The correct answer is B: To stimulate the release of an egg from the ovary. LH surge triggers ovulation, releasing the mature egg from the follicle. This is crucial for fertility. A is incorrect because progesterone maintains the uterine lining, not LH. C is incorrect as LH doesn't regulate progesterone during pregnancy, but plays a role in ovulation. D is incorrect as LH and FSH work together to regulate the menstrual cycle, not inhibit each other.

Chromosome analysis is a diagnostic test that should be offered to which couple?
- A. Never conceived.
- B. Has long-standing infertility.
- C. Has had repeated pregnancy losses.
- D. Has a normal child but has not conceived again.
Correct Answer: C
Rationale: Rationale: Choice C is correct because chromosome analysis is recommended for couples who have experienced repeated pregnancy losses to identify any genetic abnormalities that may be causing the miscarriages. This test can help determine if there are chromosomal issues that could be addressed in future pregnancies. Choices A, B, and D do not necessarily warrant chromosome analysis as they do not directly relate to the potential genetic causes of pregnancy losses.
A patient asks about the purpose of progesterone injections after embryo transfer. What should the nurse explain?
- A. They increase the number of eggs released in future cycles.
- B. They support the uterine lining for implantation and pregnancy maintenance.
- C. They prevent ovarian cyst formation during fertility treatment.
- D. They reduce pregnancy symptoms such as nausea.
Correct Answer: B
Rationale: The correct answer is B: Progesterone injections support the uterine lining for implantation and pregnancy maintenance. Progesterone is essential for preparing the uterus for implantation and maintaining a pregnancy. After embryo transfer, progesterone helps thicken the uterine lining, making it more receptive to the embryo for successful implantation. Other choices are incorrect: A is incorrect because progesterone does not affect the number of eggs released in future cycles; C is incorrect because progesterone does not prevent ovarian cyst formation; D is incorrect because while progesterone can help alleviate some pregnancy symptoms, its primary role is in supporting the uterine lining for pregnancy.
A 10-week gravid states that her sister's son has been diagnosed with an X-linked recessive disease, Duchenne muscular dystrophy. She questions the nurse about the disease. Which of the following responses is appropriate for the nurse to make?
- A. Because Duchenne muscular dystrophy is inherited through the woman
- B. it is advisable for you to see a genetic counselor.
- C. Duchenne muscular dystrophy usually occurs as a spontaneous mutation. It is very unlikely that your fetus is affected.
- D. Your child could acquire Duchenne muscular dystrophy only if both you and your husband carried the gene. You need to check your husband's family history.
Correct Answer: A
Rationale: Duchenne muscular dystrophy is X-linked recessive, meaning the mother must be a carrier for the child to be affected.
Which of the following client responses indicates that the nurse's teaching about care following chorionic villus sampling (CVS) has been successful?
- A. If the baby stops moving
- B. the woman should immediately go to the hospital.
- C. The woman should take oral terbutaline every 2 hours for the next day.
- D. If the woman starts to bleed or to contract
Correct Answer: C
Rationale: Bleeding or contractions after CVS warrant medical attention.
A nurse is explaining genetic testing options before conception. What should be included?
- A. Genetic testing guarantees a successful pregnancy.
- B. It identifies potential genetic conditions that could affect the baby.
- C. It eliminates the need for other prenatal tests.
- D. Genetic testing is only available during pregnancy.
Correct Answer: B
Rationale: The correct answer is B because genetic testing before conception can identify potential genetic conditions that could affect the baby, enabling parents to make informed decisions. This information helps in understanding the risk of passing on genetic disorders and allows for options like genetic counseling or assisted reproductive technologies. Choice A is incorrect because genetic testing does not guarantee a successful pregnancy. Choice C is incorrect as other prenatal tests may still be necessary. Choice D is incorrect as genetic testing can be done before conception as well.
