A nurse is caring for a female client who is at 42 weeks of gestation in the prenatal clinic.
Fundal height 36 cm at 42 weeks gestation
Cervix closed and thick
Vertex presentation at +1 station
Clear to white mucus-like vaginal discharge
Fetal heart rate 150/min
Nonstress test nonreactive
Positive Group B Streptococcus culture
Biophysical profile score 8/10
Correct Answer : A,F,G
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.

Correct Answer is ["A","B","E"]
Explanation
Choice A rationale
Body tremors are a key indicator of central nervous system (CNS) hyperirritability, which is a major component of neonatal abstinence syndrome (NAS) following in utero exposure to opioids like heroin. The newborn's immature CNS struggles to adapt after the abrupt cessation of the drug, leading to uncoordinated, jerky movements, exaggerated reflexes, and generalized irritability.
Choice B rationale
Tachypneic respirations (respiratory rate greater than 60 breaths/min) are a common sign of NAS. This occurs due to the dysregulation of the autonomic nervous system and increased metabolic rate associated with the hyperirritable state. Other respiratory signs include flaring, retractions, and frequent yawning or sneezing, reflecting CNS overstimulation.
Choice C rationale
The hyperirritability of the CNS in NAS typically leads to increased and exaggerated reflexes (hyperreflexia), such as a hyperactive Moro reflex, not decreased reflexes. Decreased reflexes would suggest CNS depression, which is characteristic of acute opioid intoxication, not the withdrawal state of NAS.
Choice D rationale
Newborns experiencing NAS are characterized by CNS hyperstimulation, leading to excessive wakefulness, irritability, and an inability to be consoled, often referred to as hyperactivity or agitation. Extreme lethargy and hypoactivity are signs of CNS depression or severe illness, which is contrary to the expected presentation of NAS.
Choice E rationale
The hyper-responsiveness of the newborn's CNS in NAS causes a characteristic high-pitched, non-stop, inconsolable crying. This shrill, distressed cry is due to the sustained state of irritability and neurological overstimulation, representing a significant manifestation of withdrawal symptoms that is distressing to both the newborn and the caregivers.
Correct Answer is A
Explanation
Choice A rationale
True labor contractions persist and often intensify with activity, such as walking, because physical exertion promotes the release of oxytocin. In contrast, Braxton Hicks or false labor contractions typically diminish or cease with ambulation. Therefore, contractions persisting with walking indicate the cervical changes characteristic of progression into the active phase of labor.
Choice B rationale
Urinary frequency is a common discomfort throughout the third trimester of pregnancy due to the pressure of the enlarged uterus on the bladder. While present, it is not a specific indicator of the progression of labor from the latent to the active phase, which is characterized by measurable changes in cervical dilation and effacement.
Choice C rationale
Increased blood-tinged vaginal mucus, known as "bloody show," results from the cervical capillaries breaking as the cervix effaces and dilates. While this indicates cervical change, the most definitive sign of labor progression is a change in the frequency, duration, and intensity of contractions coupled with measurable descent or cervical dilation increase.
Choice D rationale
The station is the relationship of the presenting part to the ischial spines (zero station). The client's initial station was -1 cm. A change to -3 cm station indicates the fetus has moved up and away from the ischial spines, which signifies regression, or higher negative numbers, in the engagement, not the desired progression into the maternal pelvis.
