A client's chorionic villus sampling (CVS) reveals mosaicism, but amniocentesis does not. How should the nurse evaluate these results?
1. An error in analyzing the results must have occurred because these two events cannot exist simultaneously.
2. The client has a condition called anaphase lag.
3. The client has a condition called confined placental mosaicism (CPM).
4. Mosaicism is present in the fetus, but not in the placenta.
3
Rationale 1: These two results are compatible.
Rationale 2: Anaphase lag is a mechanism for trisomy formation but is not identified in these results.
Rationale 3: The presence of mosaicism in the placenta but not in fetal tissues signifies CPM.
Rationale 4: CVS testing reveals the presence of mosaicism in the placenta. The absence of mosaicism in the amniotic fluid indicates that no fetal tissues are mosaic.
