A nurse is providing education to a client during her first prenatal visit.
Which of the following should the nurse include in the teaching to decrease the risk of preterm labor?

Choice A rationale

50% of the offspring have a chance of developing the disease from the affected parent. Autosomal dominant inheritance means that a single copy of the altered gene in each cell is sufficient to cause the disorder. Thus, each child of an affected parent has a 50% chance of inheriting the condition.

Choice B rationale

Diseases transmitted from a carrier mother to her son typically describe X-linked recessive inheritance, not autosomal dominant. In autosomal dominant conditions, both males and females can be affected, and it doesn't depend on the sex of the parent transmitting the gene.

Choice C rationale

All of the offspring will develop the disease is incorrect. In autosomal dominant inheritance, there is a 50% chance of passing the altered gene to the offspring, not 100%.

Choice D rationale

50% of the offspring will be carriers of the disease from the affected parent is incorrect for autosomal dominant inheritance. There are no "carriers" in autosomal dominant diseases; individuals either have the disease or they don't, based on whether they inherit the altered gene.

Step 1 is: October 20 + 7 days = October 27

Step 2 is: October 27 - 3 months = July 27

Step 3 is: July 27 + 1 year = July 27 next year

Final calculated answer: July 27.
