Answer to Question 1

Correct Answer: 4

A child born with a recessive condition has inherited one altered gene from the mother and one from the father. In most cases, neither of the parents is affected and therefore, each of the parents must have a single gene alteration on one chromosome of a pair and the normal, wild-type, or unaltered, form of the gene on the other chromosome. These parents would be known as carriers of the condition and they do not usually exhibit any signs and symptoms of the condition. If only one parent was affected, the child would not be born with the disorder but simply would be a carrier as well. There is no evidence to support the fact the father is not the biological father.

Answer to Question 2

Correct Answer: 2

Mitochondrial genes and any diseases due to DNA alterations on those genes are transmitted through the mother in a matrilineal pattern. An affected female will pass the metabolism DNA mutation to all of her children. An affected male will not pass the metabolism DNA mutation to any of his children. It is inappropriate for the nurse to recommend the patient not have children. This recommendation steps beyond the scope of practice. Inherited disorders exist beyond those involving chromosomes 13, 18, and 21.
