A nurse is caring for a client who is at 37 weeks of gestation and received a provider order for group B streptococcus beta-hemolytic culture.
Which of the following statements should the nurse include in the teaching?

Choice A rationale

Avoiding the preschooler's presence at prenatal visits can inadvertently promote feelings of exclusion and resentment, suggesting the new sibling is an unwelcome disruption. In contrast, involving the older child in the pregnancy experience, like listening to the fetal heartbeat, helps normalize the upcoming change and prepares them for the new family dynamic, fostering a positive adjustment. This inclusion is crucial for emotional security.

Choice B rationale

Making a significant change, such as moving the preschooler from a crib to a bed, immediately before or the day the new baby arrives, associates the loss of their comfortable sleeping arrangement with the sibling's arrival. This can be viewed as a punishment, increasing stress and anxiety and potentially fueling sibling rivalry and regression. Major changes should be made several weeks before the birth.

Choice C rationale

Planning and dedicating specific, high-quality individual time ("special time") with the preschooler reassures them of their continued importance and secures their parent-child bond. This counteracts the potential feeling of being displaced or replaced by the newborn, which is critical for maintaining their self-esteem and emotional well-being during the family transition.

Choice D rationale

Insisting the initial encounter be a visual of the parent holding the baby can immediately trigger jealousy and a sense of loss of parental attention, as the parent is focused elsewhere. Instead, the parent should greet the preschooler first with open arms and allow the child to approach the baby on their own terms, promoting a gentler, more positive introduction.

Choice A rationale: A fundal height of 36 cm at 42 weeks gestation is concerning because fundal height should approximate gestational age in weeks ±2 cm. At 42 weeks, expected measurement is about 40–44 cm. A measurement of 36 cm suggests possible intrauterine growth restriction (IUGR) or oligohydramnios, both of which are complications associated with post-term pregnancy. This discrepancy requires further evaluation with ultrasound and fetal surveillance to ensure adequate growth and amniotic fluid volume.

Choice B rationale: A cervix that is closed and thick at 42 weeks gestation is not an immediate problem requiring intervention. Cervical ripening varies, and although induction may be considered at this gestational age, the cervix itself being closed is not pathologic. It simply indicates that spontaneous labor has not yet begun. This finding does not require urgent intervention but may guide decisions about induction methods such as prostaglandins or mechanical ripening.

Choice C rationale: A vertex presentation at +1 station is a favorable finding. Vertex is the optimal presentation for vaginal delivery, and +1 station indicates that the fetal head is descending into the pelvis. This is reassuring and does not require intervention. It suggests that the fetus is well-positioned for labor and delivery, and no abnormality is present in this assessment.

Choice D rationale: Clear to white mucus-like vaginal discharge is a normal physiologic finding in pregnancy, known as leukorrhea. It results from increased estrogen and cervical gland activity. This type of discharge is not associated with infection or rupture of membranes. Since it is expected and benign, it does not require intervention. Only abnormal discharges such as foul-smelling, green, or bloody secretions would warrant further evaluation.

Choice E rationale: A fetal heart rate of 150/min is within the normal baseline range of 110 to 160 beats per minute. This indicates adequate fetal oxygenation and no evidence of tachycardia or bradycardia. Since the rate is normal and reassuring, it does not require intervention. Continuous monitoring remains important, but this specific finding is not problematic.

Choice F rationale: A nonstress test that is nonreactive is concerning because it indicates that the fetus did not demonstrate adequate accelerations of heart rate with movement. A reactive NST requires at least two accelerations of 15 beats/min above baseline lasting 15 seconds within 20 minutes. A nonreactive result suggests possible fetal hypoxemia, sleep state, or neurologic compromise. This requires further evaluation with a contraction stress test or repeat biophysical profile.

Choice G rationale: A positive Group B Streptococcus culture is abnormal and requires intervention. GBS colonization increases the risk of neonatal sepsis, pneumonia, and meningitis if transmitted during delivery. Standard care is intrapartum prophylaxis with IV penicillin or ampicillin during labor. Since this client is GBS positive, the nurse must ensure that prophylactic antibiotics are administered at the onset of labor or rupture of membranes to prevent neonatal infection.

Choice H rationale: A biophysical profile score of 8/10 is considered reassuring. The BPP assesses fetal breathing, movement, tone, amniotic fluid volume, and NST. A score of 8 to 10 indicates normal fetal well-being, while 6 is equivocal and ≤4 is abnormal. Since this client’s score is 8, no immediate intervention is required. This is a reassuring finding and does not indicate fetal compromise.
