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.
An Orthodox Jewish couple is seeking infertility counseling. The woman states that her menstrual cycle is 21 days long. After testing, no physical explanation is found for the infertility. Which of the following may explain why the woman has been unable to conceive?
- A. Her kosher diet is lacking the essential nutrients needed for achieving optimal reproductive health.
- B. The positions allowed Orthodox Jewish couples during intercourse hinder the process of fertilization.
- C. Orthodox Jewish couples are known to have a high rate of infertility because of inborn genetic diseases.
- D. Orthodox Jewish couples refrain from intercourse during menses and for seven days after it ends.
Correct Answer: D
Rationale: Orthodox Jewish couples abstain from intercourse during menstruation and the subsequent week, potentially missing the fertile window.
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 nurse is explaining the role of intrauterine insemination (IUI). What should the nurse include?
- A. IUI involves placing washed sperm directly into the uterus.
- B. IUI is used to treat structural abnormalities in the uterus.
- C. IUI guarantees fertilization of the egg.
- D. IUI eliminates the need for ovulation tracking.
Correct Answer: A
Rationale: The correct answer is A because intrauterine insemination (IUI) involves placing washed sperm directly into the uterus, increasing the chances of fertilization. This method bypasses potential obstacles in the reproductive tract, aiding sperm in reaching the egg. Choice B is incorrect because IUI is not primarily used to treat structural abnormalities in the uterus but rather to facilitate fertilization. Choice C is incorrect as IUI does not guarantee fertilization since other factors can still affect the success of conception. Choice D is incorrect because ovulation tracking is still important in IUI to ensure optimal timing for the procedure.
A woman is seeking genetic counseling during her pregnancy. She has a strong family history of diabetes mellitus.

- B. Diabetes cannot be diagnosed by looking at the genes.
- C. Although diabetes does have a genetic component
- D. diet and exercise also determine whether or not someone is diabetic.
Correct Answer: C
Rationale: Diabetes involves genetic and environmental factors.
