Question 1 of 5

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?

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.

Question 2 of 5

A patient and her husband have just been told their unborn child has Down syndrome. The patient's husband becomes upset, stating, 'There is no way this can be possible as we have no one in the family with this problem! You must run the test again because the results cannot be correct.' What does the husband's behavior represent?

Correct Answer: A

Rationale: The correct answer is A: Denial. The husband's behavior of refusing to accept the test results and requesting them to be run again indicates denial. Denial is a common defense mechanism where individuals reject reality to avoid facing uncomfortable truths. The husband's disbelief due to lack of family history reflects denial in coping with the unexpected news. Sorrow (B), Anger (C), and Bargaining (D) are not applicable in this context as the husband's reaction does not demonstrate sadness, hostility, or attempts to negotiate a different outcome.

Question 3 of 5

Chromosome analysis is a diagnostic test that should be offered to which couple?

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.

Question 4 of 5

What is a typical characteristic of polycystic ovarian syndrome (PCOS) affecting fertility?

Correct Answer: B

Rationale: The correct answer is B: Increased androgen levels. In PCOS, there is often an imbalance in hormone levels, including increased androgens like testosterone. This can disrupt normal ovulation and affect fertility. Regular ovulation (choice A) is typically not seen in PCOS. Reduced ovarian size (choice C) is not a typical characteristic, as ovaries can actually be enlarged in PCOS due to multiple small cysts. High levels of estrogen throughout the cycle (choice D) is not a defining feature of PCOS, as estrogen levels can vary in affected individuals. Ultimately, the increased androgen levels in PCOS are a key factor contributing to fertility issues in affected individuals.
