During genetic testing, one parent is found to have a chromosomal abnormality without any physical or mental disability; however, the offspring has inherited physical and/or mental disability.
 
  During patient education, the nurse explains that the type of individual who can have a chromosomal abnormality without any disability but can cause his offspring to receive chromosomal alterations and disability is the parent with: 1. Dominant-gene structural chromosomal inversions.
  2. Mosaicism.
  3. Dominant-gene structural chromosomal balanced translocations.
  4. Dominant-gene structural chromosomal deletions.

Question 2

Advances in genetic screening provide information with high levels of certainty about genetic disorders a fetus might have. Which of the following is an ethical implication of these advances?
 
  1. The nurse must be aware of parent feelings regarding the information available to them.
  2. The nurse must be aware of his own personal feelings about the actions taken after the screening tests are completed.
  3. The parents must be aware of the nurse's feelings regarding the information available about the fetus.
  4. The nurse must participate in actions that are completely contradictory to his personal ethics.

Answer to Question 1

Rationale 1: Individuals with other dominant-gene chromosomal alterations will all manifest some physical or mental abnormality themselves.
Rationale 2: The individual with mosaicism will display varying degrees of disability, depending on the percentage of cells that are affected. The clinical consequences of inversion depend on how much genetic material was rearranged.
Rationale 3: The parent with balanced translocations can show no signs of physical or mental disability but cause offspring to receive chromosomal alterations, such as trisomy 21.
Rationale 4: A genetic deletion, such as is seen with cri du chat syndrome, results from a deletion on chromosome 5. This would be obvious in the parent as well as the child.
Global Rationale:

Answer to Question 2

2

Rationale:

1. There are no ethical implications for the nurse to be aware of parent feelings about genetic screening information. In fact, the nurse does not have to know the parent feelings.
2. The nurse must be aware of his own personal feelings about possible actions following genetic screening information.
3. There are no ethical implications of the parents' being aware of the nurse's feelings unless the nurse forces those feelings and the subsequent actions on the parents.
4. The nurse does not have to participate in any action contradictory to personal ethics.
