All five of the children in a family were 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. One parent has both chromosomes with the affected gene.
  2. Both parents are carriers.
  3. One parent is a carrier and the other parent is unaffected.
  4. One parent has one chromosome affected and the other parent has none.

Question 2

A child is being discharged from the hospital following treatment of asthma. Discharge medications include cromolyn sodium (a mast cell stabilizer).
 
  Nursing instructions to the parents about this medication would include explaining: Standard Text: Select all that apply. 1. The medication works to prevent exacerbations.
  2. The medication should be administered at the first symptom of an asthmatic attack.
  3. The medication should be taken on a daily basis.
  4. Avoid taking the medication if the child has symptoms of a cold.
  5. The medication desensitizes the child against specific allergens.

Answer to Question 1

1
Rationale 1: 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.
Rationale 2: If both parents are carriers, 25 of the children should be free of the disease.
Rationale 3: For all five children to have the disorder, one parent would have to have both chromosomes affected.
Rationale 4: For all five children to have the disorder, one parent would have to have both chromosomes affected.
Global Rationale:

Answer to Question 2

1,3
Rationale 1: This statement is true. Cromolyn Sodium is used to inhibit an asthmatic response to allergens.
Rationale 2: This is incorrect. This medication does not improve the child's condition during an asthmatic attack.
Rationale 3: This is a preventative medication so doses should not be missed.
Rationale 4: The medication should be taken daily.
Rationale 5: This medication does not desensitize the child against allergens.
