A patient has been told that her unborn child will most likely have Down syndrome. The nurse realizes this diagnosis is consistent with:
1. Trisomy.
2. Monosomy.
3. Translocation.
4. Deletions.
Trisomy.
Rationale: Trisomy refers to the presence of a third or extra chromosome instead of the normal pair of a particular chromosome. The most common type of trisomy in infants is trisomy 21 or Down syndrome. The chromosome number and structure seen in 95% of individuals with Down syndrome is 47, XX or 47, XY. Monosomy refers to the presence of only one chromosome instead of the normal pair of chromosomes. Monosomy for an entire chromosome usually results in death, except for Turner syndrome or the monosomy for the X chromosome (45, X). Translocations occur when there are breaks in two or more chromosomes with reattachments in new combinations. They are generally harmless, though these translocations are more common among individuals with intellectual disabilities. Structural rearrangements of chromosomes may result from deletions or loss of a chromosome segment or piece; individuals may have moderate to severe mental retardation, Williams syndrome, or Prader-Willi syndrome.
