ATI Pediatrics Final Exam 2025 Questions
Extract:
A nurse is reinforcing education about the inheritance patterns of fragile X syndrome to a couple who have a family history of the disorder.
Question 1 of 5
Which of the following statements should the nurse make?
Correct Answer: D
Rationale: The correct answer is D because Fragile X syndrome is inherited in an X-linked dominant pattern. This means that if a pregnant client carries the gene mutation, each child has a 50% chance of inheriting the condition. The mutation is located on the X chromosome, and since males have only one X chromosome, they are more likely to be affected. Females have two X chromosomes, so they would need a mutation on both chromosomes to be affected.
Choice A is incorrect because Fragile X syndrome is not autosomal recessive.
Choice B is incorrect because it incorrectly states that all future sons will have the condition.
Choice C is incorrect because Fragile X syndrome is not inherited through mitochondrial DNA.
