What would the nurse document after assessing a neonate born at 38 weeks' gestation who weighs 8 lb 13.1 oz (4,017 g)?
Appropriate for gestational age, term.
Large for gestational age, term.
Large for gestational age, preterm.
Appropriate for gestational age, preterm.
The Correct Answer is B
Choice A rationale
Appropriate for gestational age (AGA) refers to neonates whose weight falls between the 10th and 90th percentiles for their gestational age. The neonate is term (38 weeks), but weighs 4,017 grams, which is >4,000 grams and classified as macrosomic, thus >90th percentile and not AGA. The classification of AGA is based on a statistical growth curve and is distinct from being macrosomic.
Choice B rationale
Large for gestational age (LGA) describes neonates whose weight is above the 90th percentile for their gestational age, which includes those with macrosomia (birth weight >4,000 g). This neonate weighs 4,017 g, placing them in the LGA category. Term is defined as a birth occurring between 37 weeks 0 days and 41 weeks 6 days gestation, making 38 weeks a term birth.
Choice C rationale
Large for gestational age (LGA) is correct for this 4,017 g neonate, as their weight exceeds the 90th percentile for 38 weeks' gestation. However, preterm refers to births occurring before 37 weeks 0 days gestation. Since this neonate was born at 38 weeks' gestation, the "preterm" classification is incorrect because 38 weeks is within the term range.
Choice D rationale
Appropriate for gestational age (AGA) is incorrect because this neonate's weight of 4,017 g is greater than the 90th percentile for a 38-week gestation, classifying them as large for gestational age (LGA). Term is correct as the neonate was born at 38 weeks' gestation, which is within the 37 weeks 0 days to 41 weeks 6 days range, making the overall classification inaccurate.

Correct Answer is B
Explanation
Choice A rationale
Stronger contractions are not a specific complication of breech presentation. Contraction strength is related to uterine action and response to oxytocin, not solely to fetal presentation. Breech presentation primarily poses risks related to the birthing process itself, such as cord prolapse and birth trauma.
Choice B rationale
In a breech presentation, the presenting part (buttocks or feet) is less effective than the head in filling the pelvic inlet, potentially leaving space for the umbilical cord to prolapse, especially upon rupture of membranes. Cord prolapse causes nonreassuring fetal signs such as sudden, severe variable decelerations or prolonged bradycardia due to cord compression and subsequent fetal hypoxia.
Choice C rationale
Precipitate labor is characterized by very rapid cervical dilation and fetal descent, usually occurring within three hours of labor onset. This is not directly caused by a breech presentation. The mechanism of labor in breech is often slower and more complicated due to the less efficient presenting part.
Choice D rationale
Cessation of contractions often indicates uterine fatigue or uterine inertia, which can occur in prolonged labor or with specific uterine conditions, but it is not a direct or common complication of breech presentation. Overstretching of the uterus is typically associated with polyhydramnios or multiple gestation.
Correct Answer is D
Explanation
Choice A rationale
This question focuses on general health knowledge, which, while important, doesn't directly address the client's current psychological distress and anxiety related to her history of recurrent pregnancy loss and current concern about being at home. The plan of care needs to first establish the client's understanding and perception of her current pregnancy status.
Choice B rationale
Understanding the etiology of previous spontaneous abortions, such as chromosomal abnormalities or uterine anomalies, is valuable for medical management but may not be known and doesn't immediately address the client's current, expressed anxiety about remaining at home. The most helpful response first assesses the client's current belief system regarding this specific pregnancy.
Choice C rationale
Asking about signs of an impending spontaneous abortion focuses on potential complications, which could increase the client's anxiety. While patient education is crucial, the initial priority is to understand the client's current knowledge and perception of her present pregnancy status, which is key to tailoring support.
Choice D rationale
This question is most helpful because it assesses the client's current understanding of her pregnancy's stability, which directly relates to her expressed concern about staying home. A clear understanding of the fetal and maternal status provides the necessary foundation for the nurse to plan appropriate supportive care and education.
