A client with an autosomal dominant inherited disorder is exploring family planning options. What is the key information the nurse should provide?

In the case of an autosomal dominant inherited disorder, the key piece of information for family planning is that each pregnancy carries a 50% chance of inheriting the disorder. This is due to the nature of autosomal dominant inheritance, where a single copy of the mutated gene from one parent is sufficient to cause the disorder in the offspring. Thus, regardless of the sex of the child, each has an equal opportunity to inherit the affected gene.

This understanding helps the client and their family make informed decisions about family planning, including considerations of genetic counseling and testing options. Knowing this percentage is crucial for the parents as they weigh their options and consider the implications for each potential child.
