A patient and her husband request to view the results of their infant's karyotype. An aneuploidy was noted. The nurse understands the results to indicate what?
Correct Answer: A
Rationale: Correct Answer: A
Rationale: A karyotype is a visual representation of an individual's chromosomes. An aneuploidy indicates an abnormal number of chromosomes, which can result in genetic disorders such as Down syndrome. A karyotype shows the number, size, and shape of chromosomes, so an abnormal number of chromosomes on the karyogram is the correct interpretation.
Summary of Other Choices:
B: Translocations involve the movement of genetic material between chromosomes, not an abnormal number of chromosomes.
C: Chromosomal breaks would not typically result in an aneuploidy but rather structural abnormalities.
D: Duplication of chromosomes to total 46 would not lead to aneuploidy but rather a normal chromosome count.
