Anna is a 29-year-old G2P1 who has just had a 20-week routine anatomy ultrasound. The doctor informed her that there were some “soft markers” for Down syndrome and that genetic amniocentesis is available if she wants to have it.
Question 1
Anna asks whether the ultrasound shows that the fetus has Down syndrome. How can the nurse explain the soft markers for Down syndrome?
Question 2
What counseling should Anna receive about amniocentesis?
Question 3
Anna decided to go home and discuss the findings with her family. She ultimately decided to have genetic amniocentesis and is back today for that appointment. What are the nursing implications of genetic amniocentesis?
Question 4
The results of the amniocentesis show trisomy 21. After genetic counseling, Anna chooses to continue the pregnancy. How can the nurse help Anna at this time in her pregnancy?
Here’s a breakdown of how to address Anna’s questions and concerns:
Question 1: Explaining Soft Markers
“Anna, the ultrasound didn’t show that your baby has Down syndrome. What it showed are some ‘soft markers’ which are physical characteristics that are more common in babies with Down syndrome, but they can also occur in babies who are perfectly healthy. These markers are not a diagnosis, but they do indicate a slightly higher chance of Down syndrome. It’s important to remember that most babies with these markers do not have Down syndrome.”
Examples of Soft Markers: You can explain specific markers the doctor might have mentioned, such as increased nuchal translucency (fluid at the back of the neck), shortened femur length, or certain facial features.
Importance of Genetic Testing: “The doctor offered you amniocentesis to get a definitive answer about whether your baby has Down syndrome. This test will analyze the baby’s chromosomes and provide a more accurate diagnosis.”
Question 2: Amniocentesis Counseling
Purpose: Explain the purpose of amniocentesis, which is to identify chromosomal abnormalities.
Procedure: Describe the procedure, including the risks and benefits.
Risks: Miscarriage (about 1 in 200 cases), bleeding, infection, premature labor.
Benefits: Provides a definitive diagnosis of Down syndrome, allowing the parents to make informed decisions.
Timing: Inform her that amniocentesis is usually performed between 15 and 20 weeks of pregnancy.
Results: Explain that the results typically take a few weeks to come back.
Support: Emphasize that she has the right to choose whether or not to have amniocentesis, and that she should make the decision that feels right for her and her family. Offer to connect her with genetic counseling resources if needed.
Question 3: Nursing Implications of Amniocentesis
Informed Consent: Ensure that Anna understands the procedure, risks, and benefits, and that she has signed informed consent.
Preparation: Ensure that Anna has a full bladder for the procedure.
Comfort: Provide comfort measures, such as emotional support, pillows for positioning, and a distraction technique.
Post-Procedure: Monitor Anna for any signs of complications, such as bleeding, cramping, or fever. Advise her to rest for the remainder of the day.
Follow-Up: Schedule a follow-up appointment to review the results and discuss further steps.
Question 4: Support After a Positive Diagnosis
Emotional Support: Acknowledge the emotional impact of the diagnosis and offer empathy and support.
Information and Resources: Provide Anna with information and resources about Down syndrome, including support groups, organizations, and websites.
Decision-Making Support: Encourage Anna to discuss her options with her family, medical team, and genetic counselor. Offer to assist with making appointments or finding resources.
Pregnancy Care: Ensure that Anna receives appropriate prenatal care, including monitoring for potential complications associated with Down syndrome.
Long-Term Planning: Help Anna understand the potential challenges and resources available as she plans for her baby’s future.
