Anna Is A 29-Year-Old G2P1 Who Just Had A 20-Week Routine

Anna Is A 29 Year Old G2p1 Who Has Just Had A 20 Week Routine Anatomy

Anna is a 29-year-old woman who has recently undergone a routine 20-week fetal anatomy ultrasound. During the ultrasound, the physician identified some "soft markers" suggestive of Down syndrome (trisomy 21). The physician informed her about these soft markers and explained that genetic amniocentesis is available if she wishes to undergo further testing. Anna has questions regarding the significance of the soft markers and the implications of amniocentesis. She eventually decided to proceed with amniocentesis, and the results confirmed trisomy 21. She chose to continue the pregnancy and seeks support and guidance moving forward. The purpose of this paper is to address Anna’s inquiries about the soft markers, discuss counseling about amniocentesis, outline nursing implications of the procedure, and describe how to support her upon learning the diagnosis and continuing her pregnancy.

Understanding Soft Markers for Down Syndrome

Soft markers are subtle ultrasound findings that are not anomalies themselves but are associated with an increased risk of certain chromosomal abnormalities such as Down syndrome (Chervenak et al., 2018). These markers include a number of fetal features, such as increased nuchal translucency, echogenic intracardiac focus, choroid plexus cysts, mild ventriculomegaly, hyperechoic bowel, and pyelectasis. It is important for the nurse and healthcare provider to explain to Anna that these markers are not definitive diagnoses but suggest a need for further testing and counseling based on the increased risk profile (American College of Obstetricians and Gynecologists [ACOG], 2016). Soft markers can occasionally be seen in fetuses with chromosomal abnormalities, but they can also be present in normal fetuses, thus, they require careful interpretation within the context of other screening results and prenatal history.

The presence of soft markers typically warrants additional assessment, such as non-invasive screening tests like cell-free fetal DNA testing, which has high sensitivity and specificity for detecting trisomy 21 (Benn et al., 2018). The healthcare team aims to provide clear information so that Anna can understand that soft markers increase the probability but do not confirm an abnormality independently.

Counseling About Amniocentesis

Amniocentesis is an invasive diagnostic procedure in which a small amount of amniotic fluid is extracted from the amniotic sac surrounding the fetus for chromosomal analysis (ACOG, 2016). It provides definitive information about fetal karyotype, including the presence of trisomy 21. When counseling Anna about amniocentesis, nurses should inform her about the procedure’s benefits, risks, and limitations.

The benefits include obtaining a definitive diagnosis of chromosomal abnormalities, which can assist in making informed decisions regarding the pregnancy (Wapner et al., 2016). Risks encompass a small chance of miscarriage (approximately 0.1%-0.3%), infection, placental injury, or premature rupture of membranes (ACOG, 2016). The nurse should emphasize that the procedure is generally safe but that informed consent is essential. It is also important to prepare her psychologically for possible outcomes and to discuss her feelings and preferences regarding the information gained from the procedure.

Nurses should ensure that Anna understands that results may take a few days and that genetic counseling is available to interpret her results and discuss implications. Ethical considerations, including her values and support system, should also be addressed to help her make an informed choice about proceeding with further testing and managing her pregnancy.

Nursing Implications of Genetic Amniocentesis

Following the decision to proceed with amniocentesis, nurses play a critical role in preparing Anna, providing emotional support, and managing care around the procedure. Prior to the procedure, nurses should verify informed consent, review her medical history, and ensure she understands the instructions, such as hydrating adequately and emptying her bladder (Wapner et al., 2016).

During the procedure, the nurse may assist with positioning and comfort measures. Afterward, observation for signs of complications, such as abdominal cramping, bleeding, fever, or fluid leakage, is essential. Anna should be advised to rest for the remainder of the day and to avoid strenuous activity for a few days after the procedure (ACOG, 2016).

Follow-up includes providing emotional support, acknowledging her feelings regardless of the results, and discussing next steps. If the results are positive for trisomy 21, ongoing prenatal care, support, and discussions about potential outcomes and management options are necessary. Documentation of the procedure, findings, and discharge instructions is essential for continuity of care.

Supporting Anna After a Diagnosed Trisomy 21 and Continuing the Pregnancy

When the amniocentesis confirms trisomy 21, and Anna chooses to continue her pregnancy, the nurse’s role expands to providing comprehensive emotional support, education, and preparation for the remaining pregnancy and motherhood. Conveying empathy and validating her feelings are vital during this emotionally charged time (Nelson & Burns, 2019).

The nurse should offer information about Down syndrome, including common health issues, developmental expectations, and available resources such as genetic counseling, early intervention programs, and support groups. Preparing Anna for the potential medical needs of her baby, possible developmental delays, and facilitating access to pediatric specialists can empower her to make informed decisions about her prenatal care.

Supportive counseling must also focus on assisting Anna with coping strategies, addressing fears or anxieties, and reinforcing her autonomy in decision-making. Encouraging her to involve her family and support system provides additional emotional stability. Continual reassurance that healthcare providers will be available to assist her throughout her pregnancy and after birth fosters confidence and reduces anxiety.

In addition, nurses should advocate for a multidisciplinary approach involving obstetricians, pediatric specialists, and social services to ensure comprehensive care for the infant and family. Respectful communication, empathy, and patient-centered care are fundamental to supporting Anna through her pregnancy journey.

Conclusion

The identification of soft markers during a fetal ultrasound can understandably cause anxiety for expectant mothers like Anna, but it also offers an opportunity for early detection of potential chromosomal abnormalities. Nurses and healthcare providers must deliver clear, compassionate explanations of what soft markers signify and guide patients through the decision-making process regarding invasive testing such as amniocentesis. Following the procedure, understanding the nursing implications, including pre- and post-care, is crucial to ensure safety and emotional support. When a diagnosis of trisomy 21 is confirmed, ongoing counseling, education, and supportive care enable women like Anna to make informed choices and adapt successfully to their pregnancy and anticipated parenting journey. A comprehensive, empathetic approach ensures that women receive not only medical care but also emotional and psychological support during this complex process.
