A nurse is caring for a female client who is at 30 weeks of gestation in the labor and delivery unit.

Exhibits

The nurse is reviewing the client's assessment data. For each assessment finding below, click to specify if the finding is consistent with placenta previa, preterm labor, or abruptio placenta. Each finding may be consistent with more than one condition

Choice A rationale: Uterine contractions occurring every 2 to 3 minutes at 30 weeks gestation are abnormal and indicate preterm labor. Normal uterine activity in the third trimester should not demonstrate such frequency or cervical change until term. The presence of cervical dilation (2 cm) and effacement (80%) confirms labor physiology. Preterm labor poses risks of neonatal respiratory distress, intraventricular hemorrhage, and sepsis. Therefore, this finding requires immediate follow-up to prevent complications associated with premature birth.

Choice B rationale: Abdominal assessment revealed a soft, nontender abdomen with no rebound tenderness. These findings are within normal limits and do not suggest acute abdominal pathology such as placental abruption, appendicitis, or peritonitis. In obstetrics, concerning abdominal findings would include rigidity, tenderness, or guarding. The absence of these signs indicates no emergent intra-abdominal complication. Thus, this assessment does not require follow-up, as it reflects a physiologically normal abdominal exam for a pregnant client.

Choice C rationale: Fundal height at 30 weeks gestation is expected to measure approximately 28 to 32 cm, correlating with gestational age ±2 cm. This client’s fundal height of 28 cm falls within the normal range. Deviations greater than 3 cm could indicate intrauterine growth restriction, oligohydramnios, or macrosomia. Since the measurement is consistent with gestational norms, it does not require follow-up. This finding is physiologically appropriate and does not suggest pathology or abnormal fetal growth at this stage of pregnancy.

Choice D rationale: Abdominal cramping in the third trimester, when associated with cervical dilation and effacement, is a hallmark of preterm labor. Unlike benign Braxton Hicks contractions, which are irregular and non-progressive, these cramps are accompanied by cervical change and regular contractions. This indicates true labor physiology before 37 weeks. Preterm labor increases risks of neonatal morbidity and mortality. Therefore, abdominal cramping in this context requires follow-up to initiate interventions such as tocolysis, corticosteroids, and infection evaluation.

Choice E rationale: Low back pain in pregnancy can be benign due to musculoskeletal strain, but in this case, it is associated with uterine contractions, cervical change, and rupture of membranes. Low back pain is a common presenting symptom of preterm labor due to referred pain from uterine activity. Additionally, fever (38.3°C) and elevated WBC count (22,000/mm³; normal 5,000–10,000/mm³) raise concern for intra-amniotic infection. Thus, low back pain here is pathologic and requires follow-up to rule out chorioamnionitis and manage preterm labor.

Choice A rationale

Bilirubin monitoring is critical for jaundice due to hemolysis, often seen in ABO incompatibility or cephalohematoma. While Large for Gestational Age (LGA) infants can have polycythemia, hypoglycemia is a more immediate and life-threatening risk that requires priority monitoring in the first hours of life. The normal total bilirubin range is typically less than 5 mg/dL in the first 24 hours.

Choice B rationale

LGA infants are often born to mothers with uncontrolled or gestational diabetes, leading to fetal hyperinsulinism. After birth, the maternal glucose supply is cut off, and the high insulin levels persist, causing a rapid and profound drop in the newborn's blood glucose, hence hypoglycemia is a major concern. The normal newborn glucose range is 40 to 60 mg/dL and should be monitored.

Choice C rationale

White blood cell (WBC) count is primarily monitored to detect neonatal sepsis or infection. While all newborns are at risk, the LGA classification does not inherently place them at a higher, unique risk for infection compared to the immediate metabolic derangement risks like hypoglycemia. The normal WBC count range is 9,000 to 30,000 cells/mm.

Choice D rationale

Arterial Blood Gases (ABGs) are used to assess the newborn's respiratory status and acid-base balance, particularly in respiratory distress syndrome or persistent pulmonary hypertension. While LGA infants can experience birth trauma or meconium aspiration, ABG monitoring is not routine unless significant respiratory symptoms are present.
