Question 1 of 5
What is the chance that this couple will have a child with six toes?
Correct Answer: A
Rationale: When two carrier parents have children together, they have a 25% chance of having a child who inherits the gene mutation from each parent and who will have the condition, as in autosomal recessive inheritance. The other percentages are incorrect for this inheritance pattern.
Question 2 of 5
The nurse informs the patient that genetic counseling and prenatal testing should be performed for all pregnant women in which age group?
Correct Answer: C
Rationale: Women who are 35 years of age or older have an increasing chance of giving birth to infants with chromosomal differences, such as trisomy 21. For this reason, genetic counseling and prenatal testing are recommended for all pregnant women above this age.
Question 3 of 5
What is an essential component of care for this patient?
Correct Answer: D
Rationale: The provision of genetic counseling, evaluation, and testing for the disease is essential in care, especially given the family history of Huntington disease. This encompasses assessing risks to offspring and addressing symptoms, making it the most comprehensive option.
Question 4 of 5
After the couple receives the results of genetic testing, the nurse should prioritize which of the following?
Correct Answer: B
Rationale: Following the communication of the findings of genetic testing, it is important that patients receive thoughtful and thorough support to address emotional and psychological impacts. Secondary prevention, gene therapy, or treatment adherence may not be immediately relevant.
Question 5 of 5
For what health problem would a patient of African American heritage most likely have genetic carrier testing?
Correct Answer: B
Rationale: Assessing ancestry and ethnicity is important to help identify individuals who could benefit from genetic testing for carrier identification, such as African Americans routinely offered testing for sickle cell anemia. The other conditions are not specifically associated with African American heritage.
