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.

The nurse is analyzing the pedigree shown below. How should the nurse interpret the genotype of the individuals in locations IV-9 and IV-10?
- A. Fraternal twins.
- B. Unaffected couple.
- C. Proband and sister.
- D. Known heterozygotes.
Correct Answer: D
Rationale: The symbols indicate known heterozygotes.
A patient undergoing IUI asks how the procedure increases the chances of conception. What should the nurse explain?
- A. IUI bypasses the cervix, placing sperm directly in the uterus.
- B. IUI enhances egg quality before fertilization.
- C. IUI eliminates the need for ovulation tracking.
- D. IUI combines egg and sperm outside the body before transfer.
Correct Answer: A
Rationale: The correct answer is A because IUI (Intrauterine Insemination) bypasses the cervix and places sperm directly in the uterus, increasing the chances of sperm reaching the fallopian tubes to fertilize the egg. This method improves the sperm's proximity to the egg, optimizing the chances of conception. The other choices are incorrect because B (enhancing egg quality) is not achieved through IUI, C (eliminating ovulation tracking) is not true as tracking is still necessary for timing the procedure, and D (combining egg and sperm outside the body) describes in vitro fertilization (IVF), not IUI.
The parents have just received news that their infant has sickle cell disease. They ask the nurse if this could happen to future children. Because this is an example of an autosomal-recessive inheritance, what should the nurse tell Tim and Katie?
- A. Because this child has sickle cell, there is a decreased chance none of your other children will have sickle cell disease.
- B. Each time you get pregnant, there will be a 50/50 chance that your child will have sickle cell disease.
- C. Each time you get pregnant, there will be a 25% chance that your child will inherit the gene from each parent and will have sickle cell disease.
- D. Your next child will have a 50% chance of being a carrier for sickle cell disease.
Correct Answer: C
Rationale: The correct answer is C: Each time you get pregnant, there will be a 25% chance that your child will inherit the gene from each parent and will have sickle cell disease. This is because sickle cell disease follows an autosomal-recessive inheritance pattern, meaning both parents must pass on the sickle cell gene for a child to have the disease. With each pregnancy, there is a 25% chance that the child will inherit one sickle cell gene from each parent, resulting in the disease. Choices A and D are incorrect because they do not accurately reflect the inheritance pattern of sickle cell disease. Choice B is incorrect because it suggests a 50/50 chance, which is not the case with autosomal-recessive inheritance.
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.
Lisa, a 35-year-old practicing attorney and marathon runner, presents to the clinic with a complaint of irregular menses. She tells the nurse, 'My husband and I want to start a family but it hasn't happened yet. We stopped using birth control 6 months ago. Should we be concerned?' What is the nurse's best response?
- A. Relax and it will happen.
- B. No, infertility is the failure to conceive after 1 year of unprotected intercourse.
- C. Aging and extreme exercise regimens may impact fertility. You should address your concerns with your provider during today's visit.
- D. Decreasing your exercise frequency and intensity will increase your chances of conceiving.
Correct Answer: C
Rationale: The correct answer is C because it acknowledges the potential impact of aging and extreme exercise on fertility, prompting further evaluation by the healthcare provider. Lisa's age and intense exercise regimen are important factors to consider since they can affect her ability to conceive. By addressing her concerns during the visit, the nurse can gather more information, assess potential fertility issues, and provide appropriate guidance or referrals.
Choice A is incorrect because it dismisses Lisa's concerns without addressing potential underlying issues. Choice B is incorrect as it sets a timeline for infertility diagnosis that is generally accepted after 1 year of unprotected intercourse for women under 35 years old, but Lisa's age and lifestyle may warrant earlier evaluation. Choice D is incorrect as it oversimplifies the issue by suggesting only a change in exercise routine as a solution without considering other potential factors impacting fertility.
