Introduction
This comprehensive assessment is designed to evaluate the knowledge, clinical
judgment, and decision-making skills essential for safe and effective maternal-newborn
nursing practice. The examination assesses foundational theory, applied professional
knowledge, regulatory compliance, and ethical standards across the perinatal
continuum. Questions are structured in multiple-choice and scenario-based formats to
simulate real-world clinical situations, emphasizing critical thinking, prioritization, and
evidence-based interventions. This assessment prepares candidates for professional
practice by requiring the application of core competencies to diverse patient
presentations and high-acuity obstetric scenarios.
Section One: Questions 1–300
1. A nurse is assessing a client at 32 weeks of gestation who presents with painless,
bright red vaginal bleeding. Which condition should the nurse suspect?
A. Abruptio placentae
,B. Placenta previa
C. Uterine rupture
D. Vasa previa
✔✔ B. Placenta previa
RATIONALE: Placenta previa classically presents with painless, bright red vaginal
bleeding in the second or third trimester. Abruptio placentae typically presents with
dark red bleeding and painful uterine tenderness. Digital vaginal examination is
contraindicated until placental location is confirmed.
2. A laboring client has recurrent late decelerations despite position change and
oxygen administration. Which action is the priority?
A. Increase the oxytocin infusion rate
B. Prepare for immediate cesarean birth
C. Administer a fluid bolus and continue monitoring
D. Perform a sterile vaginal exam to assess dilation
✔✔ B. Prepare for immediate cesarean birth
RATIONALE: Recurrent late decelerations unresponsive to intrauterine resuscitation
indicate fetal hypoxemia and require immediate delivery. Continuing oxytocin or relying
solely on fluid boluses delays definitive intervention.
3. A postpartum client has a boggy uterus and heavy vaginal bleeding. Which
medication should the nurse anticipate administering first?
A. Methylergonovine 0.2 mg IM
B. Carboprost 250 mcg IM
C. Oxytocin 10 units IM
D. Misoprostol 800 mcg sublingual
✔✔ C. Oxytocin 10 units IM
,RATIONALE: Oxytocin is first-line for uterine atony because it is rapid-acting and safe
for most clients. Methylergonovine is contraindicated in hypertension, and carboprost
is contraindicated in asthma.
4. A newborn has acrocyanosis, heart rate 120, grimace, some flexion, and slow
irregular respirations. What Apgar score should the nurse assign?
A. 5
B. 6
C. 7
D. 8
✔✔ B. 6
RATIONALE: Acrocyanosis = 1, heart rate 120 = 2, grimace = 1, some flexion = 1, slow
irregular respirations = 1. Total = 6.
5. Which finding in a client at 34 weeks of gestation most suggests severe preeclampsia
with severe features?
A. Blood pressure 148/92 mm Hg
B. 1+ proteinuria on dipstick
C. Platelet count 95,000/mm³
D. Mild dependent edema
✔✔ C. Platelet count 95,000/mm³
RATIONALE: Thrombocytopenia less than 100,000/mm³ is a severe feature of
preeclampsia. Blood pressure 148/92 is in the nonsevere range, and 1+ proteinuria is
not diagnostic of severe features.
6. Which intervention best prevents early-onset group B streptococcal disease in a
newborn?
A. Administering penicillin to the newborn after birth
B. Intrapartum intravenous penicillin prophylaxis to the mother
C. Performing a newborn blood culture at 24 hours
, D. Giving the mother oral amoxicillin at 36 weeks
✔✔ B. Intrapartum intravenous penicillin prophylaxis to the mother
RATIONALE: Intrapartum IV penicillin is the standard for GBS prophylaxis and reduces
vertical transmission. Newborn penicillin after birth and oral amoxicillin at 36 weeks are
not recommended prevention strategies.
7. A client receiving magnesium sulfate has a respiratory rate of 11 breaths/min. Which
finding typically precedes this sign of toxicity?
A. Absent deep tendon reflexes
B. Diminished deep tendon reflexes
C. Seizure activity
D. Cardiac arrest
✔✔ B. Diminished deep tendon reflexes
RATIONALE: Loss or diminution of deep tendon reflexes is the earliest clinical sign of
magnesium toxicity. Respiratory depression follows reflex changes, and cardiac arrest
is a late manifestation.
8. A client at 10 weeks of gestation is Rh-negative. Which intervention should the nurse
anticipate?
A. Administer Rho(D) immune globulin immediately at this visit
B. Administer Rho(D) immune globulin at 28 weeks and within 72 hours after delivery if
the newborn is Rh-positive
C. Monitor for hypernatremia every two weeks
D. Schedule a cesarean birth at 37 weeks
✔✔ B. Administer Rho(D) immune globulin at 28 weeks and within 72 hours after
delivery if the newborn is Rh-positive
RATIONALE: Standard prophylaxis for Rh-negative clients includes Rho(D) immune
globulin at 28 weeks and postpartum within 72 hours if the newborn is Rh-positive.
