When explaining the risk for having a child with cystic fibrosis to a husband and wife, the nurse should tell them:
1. The risk is greatest when both clients have the recessive gene.
2. The gene is carried on the X chromosome and there is little risk.
3. The disease will only occur if the child is a male.
4. The disease does not have a genetic basis.
Cystic fibrosis is an autosomal recessive genetic disorder. This means that both parents have the gene. There is a one in four chance with each pregnancy from such parents that the child will have cystic fibrosis.
