A primigravid client is seen for her first visit in the antenatal clinic and tells the nurse that her brother was born with cystic fibrosis (CF). When teaching the client about this disorder, the nurse should include which of the following? Select all that apply.

1. Asian Americans have the highest inheritance rates.

2. To inherit CF, each parent must carry a recessive trait for the disease.

3. If both parents carry the trait, each offspring has a 25% chance of inheriting the disease.

4. Fetal testing can occur by checking the shape of the red blood cells.

5. Chorionic villi sampling (CVS) can identify prenatally if their child carries the trait or has the disease.
