The nurse observes that many of the children affected by genetic aneuploidy have defects in cognition and mental function. How would the genetics nurse specialist explain this phenomenon?
1. A decrease in oxygenation through the placenta results in the dysfunction of brain cells.
2. Many of the chromosomes affected by these disorders are involved in the development of the brain and spinal cord.
3. Because of chromosomal alterations, the brain tissues are unable to release the toxins associated with metabolism.
4. Aneuploidy results in slight variations in the fetus's thermal control, and sensitive tissues such as the brain, heart, and liver are damaged.
2
Rationale 1: A decrease in oxygenation from the placenta is not common to all these disorders.
Rationale 2: The changes in chromosomes associated with brain and spinal cord development result in an alteration of mental capacity.
Rationale 3: There are no such changes associated with aneuploidy.
Rationale 4: No change in thermal control occurs in aneuploidy.
