A nurse is providing prenatal education to a group of pregnant clients.
Which among these conditions would the nurse tell the clients is a fetal condition of a high-risk pregnancy?

Choice A rationale

Choice A rationale:

Alcohol is a known teratogen that easily crosses the placenta, potentially causing fetal alcohol spectrum disorders. Since there is no established safe level of alcohol consumption during pregnancy, complete abstinence is recommended for women planning to conceive. This prevents permanent neurodevelopmental delays and structural abnormalities. Educating women on this risk during the preconception period ensures the fetus is not exposed during the critical first weeks.

Choice B rationale

Identifying inherited conditions allows for genetic counseling and informed decision-making before conception. Many genetic disorders, such as cystic fibrosis or sickle cell anemia, can be screened for to determine the risk of transmission. Knowing these risks enables the couple to explore options like prenatal diagnosis or preimplantation genetic testing. This proactive approach reduces the likelihood of unexpected neonatal complications and allows for specialized birth planning.

Choice C rationale

Achieving a healthy weight, defined as a body mass index between 18.5 and 24.9, reduces risks of gestational diabetes and hypertension. Obesity is linked to increased rates of neural tube defects and cesarean deliveries, while being underweight increases the risk of preterm birth. Optimizing weight before pregnancy ensures a better hormonal balance for ovulation and creates a more favorable intrauterine environment for the developing embryo and placenta.

Choice D rationale

This choice is incorrect because folic acid is vital for preventing neural tube defects like spina bifida. Women of childbearing age should take 400 to 800 micrograms of folic acid daily starting at least one month before conception. Folic acid aids in DNA synthesis and cell division. Refraining from its use would significantly increase the risk of serious midline developmental failures in the fetus during the early weeks.

Choice E rationale

Updating vaccinations, particularly for rubella and varicella, protects both the mother and the fetus from preventable infections. Live virus vaccines cannot be administered during pregnancy due to theoretical risks to the fetus. Therefore, ensuring immunity before conception prevents congenital rubella syndrome, which can cause deafness, heart defects, and cataracts. This intervention is a cornerstone of preconception care to ensure maternal and fetal safety.

Choice A rationale

Using only one finger for chest compressions on an infant is insufficient to generate the force necessary to compress the chest wall. Effective CPR requires the heart to be squeezed between the sternum and the spine to maintain cardiac output and systemic perfusion. One finger does not provide enough surface area or pressure to achieve the required depth of approximately 1.5 inches or one-third the anterior-posterior diameter of the chest, leading to inadequate blood flow.

Choice B rationale

For a single rescuer performing CPR on a 6-month-old infant, the two-finger technique is the evidence-based standard. The nurse places two fingers on the breastbone, just below the nipple line, to perform compressions. This technique allows for the precise application of pressure on the small surface area of an infant's chest. It ensures that the rescuer can reach the appropriate depth of 4 cm while allowing for full chest recoil, which is critical for coronary artery filling.

Choice C rationale

The heel of one hand is the technique typically reserved for children who have reached the age of one or more, depending on their physical size. For a 6-month-old infant, the heel of a hand is too large and covers too much of the thoracic cavity. This could result in trauma to the ribs or internal organs, such as the liver or spleen, because the pressure is not localized over the sternum, where it is most effective.

Choice D rationale

The heel of two hands is the technique utilized for adult CPR and is never appropriate for an infant. The force generated by two hands would cause catastrophic skeletal and internal injury to a 6-month-old. Infants have very compliant chest walls, and the excessive pressure from an adult-style compression would likely result in multiple rib fractures and lung contusions, making successful resuscitation impossible due to the severe mechanical damage inflicted during the process. .
