The patient received a narcotic analgesic during the transition stage of labor.
Which of the following will the nurse assess for in the newborn?

Choice A rationale

Folic acid, which is a B vitamin (B9), plays a critical role in DNA synthesis, cell division, and the development of the neural tube in the early weeks of gestation, often before a woman realizes she is pregnant. A daily intake of 400 micrograms (0.4 mg) of folic acid for at least one month prior to conception and throughout the first trimester is strongly recommended to significantly reduce the risk of neural tube defects like anencephaly and spina bifida.

Choice B rationale

While folic acid is necessary for the production of red blood cells and is used in the treatment of megaloblastic or macrocytic anemias, this is not the primary reason for recommending its use in the preconception period. The most crucial and time-sensitive preventative benefit for the developing fetus is the prevention of serious neural tube defects. The anemia treatment is a secondary benefit not directly related to pregnancy planning.

Choice C rationale

Although some folic acid is present in enriched grains and cereals, the amount obtained through diet alone is often insufficient and unreliable to meet the increased demands for preventing neural tube defects. Supplementation is specifically recommended in the preconception period to ensure consistently adequate blood levels, which are critical during the first 28 days of gestation for neural tube closure.

Choice D rationale

This statement is factually incorrect and potentially dangerous. Adequate folic acid intake is unequivocally essential in the periconceptional period to ensure proper development of the fetal central nervous system and prevent severe, lifelong birth defects known as neural tube defects, making it one of the most vital preconception interventions. .

Choice A rationale

Vaginal examinations require aseptic technique to prevent ascending infection, especially after membrane rupture. The nurse should use a single, sterile glove on the examining hand for each examination, not two clean gloves, as the clean technique is insufficient for this invasive procedure.

Choice B rationale

The ideal position for a vaginal examination during labor is the dorsal recumbent position, with the woman lying on her back with knees bent and hips flexed, allowing for optimal access and comfort. The supine position without hip flexion may be less comfortable and limit access, though it is often used.

Choice C rationale

Open communication is a key component of patient-centered care during labor. Discussing findings, such as cervical dilation, effacement, and fetal station, with the woman and her partner helps them understand the progress of labor, decreases anxiety, and promotes participation in the birthing process.

Choice D rationale

While regular assessment is necessary, performing a vaginal examination at least once every hour during the active phase of labor is excessive and increases the risk of intrauterine infection. The exam should be performed judiciously, typically every two to four hours, or when clinically indicated (e.g., strong urge to push, suspicion of a complication).
