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","D","E"]
Explanation
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.
Correct Answer is C
Explanation
Choice A rationale
The car seat harness straps should be positioned at or slightly below the baby's shoulders when the car seat is installed rear-facing. Positioning the straps above the shoulders could allow the baby to slide up and out of the harness in a crash due to the forces involved, compromising the restraint system's effectiveness and increasing injury risk.
Choice B rationale
The retainer clip, also called the chest clip, must be positioned at the level of the armpits across the center of the chest or sternum, not the abdomen. This critical placement ensures that the harness straps are kept correctly positioned over the baby's shoulders, preventing the straps from slipping off during a collision and maintaining optimal force distribution across the torso.
Choice C rationale
A 45-degree recline angle for a rear-facing car seat is generally recommended to prevent the infant's head from falling forward, which can compromise the airway, particularly in newborns or infants with poor head control. This specific angle is crucial for maintaining a safe and open airway and is often achieved using built-in level indicators on the car seat base.
Choice D rationale
Current safety recommendations advise keeping a child in a rear-facing car seat as long as possible, typically until they reach the maximum weight or height limit allowed by the car seat manufacturer, which often extends well beyond 12 months of age, frequently up to 2 to 4 years of age, for maximum spinal protection.
