A family has had all five of their children born with a genetic disorder. The disorder is inherited as autosomal dominant. If this is not a statistical rarity, the likelihood would be that:
 
  1. Both parents are carriers.
 
  2. One parent is a carrier and the other parent is unaffected.
 
  3. One parent has both chromosomes with the affected gene.
 
  4. One parent has one chromosome affected and the other parent has none.

Question 2

The charge nurse on a hospital unit is developing plans of care related to separation anxiety. The charge nurse recognizes that the hospitalized child who is at greatest risk for experiencing separation anxiety when parents cannot stay is the:
 
  1. Six-month-old.
  2. 18-month-old.
  3. Four-year-old.
  4. Six-year-old.

Answer to Question 1

3

Rationale:

1. If both parents are carriers, 25 of the children should be free of the disease.
2. For all five children to have the disorder, one parent would have to have both chromosomes affected.
3. It takes only one chromosome to cause the defect in the child. If one parent has both chromosomes affected, every child would receive the affected chromosome.
4. For all five children to have the disorder, one parent would have to have both chromosomes affected.

Answer to Question 2

2
Rationale 1: The six-month-old does not experience separation anxiety, which usually begins at around one year of age.
Rationale 2: The young toddler is at greatest risk. Toddlers are the group most at risk for a stressful experience when hospitalized. Separation from parents increases this risk greatly.
Rationale 3: The four-year-old is past the age when separation anxiety would be most prevalent.
Rationale 4: The six-year-old is attending school and is used to short periods of separation from parents.
