,Q1 ANALYZE COMPLEX MATERNAL AND FETAL ASSESSMENT DATA TO FORMULATE
NURSING DIAGNOSES AND INTERVENTIONS
A patient at 32 weeks gestation presents with new-onset hypertension, proteinuria,
and elevated liver enzymes. Which pathophysiologic mechanism is most directly
implicated in the development of these findings?
A. Excessive trophoblast invasion leading to uterine overdistention
B. Inadequate remodeling of spiral arteries causing placental ischemia CORRECT
C. Maternal immune tolerance promoting systemic vasodilation
D. Increased progesterone production leading to cholestasis
RATIONALE: Preeclampsia is characterized by defective trophoblast invasion and inadequate
spiral artery remodeling, resulting in placental hypoperfusion and release of anti-angiogenic
factors (e.g., sFlt-1) that cause endothelial dysfunction, hypertension, and proteinuria. Excessive
trophoblast invasion is not typical; rather, it is shallow. Immune tolerance is altered but not
primarily vasodilatory, and progesterone does not cause these findings.
Q2 ANALYZE COMPLEX MATERNAL AND FETAL ASSESSMENT DATA TO FORMULATE
NURSING DIAGNOSES AND INTERVENTIONS
A laboring patient at 41 weeks has an intrauterine pressure catheter showing
tachysystole (7 contractions in 10 minutes) with variable decelerations. Which
intervention should the nurse implement first?
A. Place the patient in a knee-chest position
B. Administer terbutaline subcutaneously
C. Discontinue oxytocin infusion CORRECT
D. Apply fetal scalp electrode for continuous monitoring
RATIONALE: The first action for tachysystole with fetal heart rate decelerations is to reduce
uterine activity by discontinuing the oxytocin infusion. Position change and terbutaline are
secondary if the pattern persists, but stopping the exogenous oxytocin is the immediate priority. A
fetal scalp electrode is not indicated and does not address the cause.

,Q3 ANALYZE COMPLEX MATERNAL AND FETAL ASSESSMENT DATA TO FORMULATE
NURSING DIAGNOSES AND INTERVENTIONS
Which of the following represents the most accurate interpretation of a
biophysical profile (BPP) score of 6 with a normal amniotic fluid volume?
A. Fetus is acidotic and requires immediate delivery
B. Fetus is reactive but at risk for chronic hypoxia CORRECT
C. Fetus is likely to have a congenital anomaly
D. Fetus is well-oxygenated with no further testing needed
RATIONALE: A BPP score of 6 is equivocal (borderline) and indicates the need for further
evaluation, often within 24 hours. Normal amniotic fluid volume suggests that acute hypoxia is
less likely, but the lack of multiple acute markers (e.g., fetal breathing, movement, tone) may
indicate chronic hypoxia. Immediate delivery is not indicated unless other variables are abnormal.
A score of 6 does not diagnose anomalies.
Q4 ANALYZE COMPLEX MATERNAL AND FETAL ASSESSMENT DATA TO FORMULATE
NURSING DIAGNOSES AND INTERVENTIONS
A postpartum patient with a third-degree perineal laceration reports severe
perineal pain and a sensation of rectal pressure. On assessment, the nurse notes
a bluish bulge at the vaginal introitus. What is the priority action?
A. Apply ice packs and elevate the hips
B. Insert a rectal tube to relieve pressure
C. Notify the provider immediately for possible hematoma evacuation CORRECT
D. Document the findings and reassess in 1 hour
RATIONALE: A bluish, bulging mass with severe pain and pressure suggests a vulvar or vaginal
hematoma, which can cause significant blood loss and shock. Immediate provider notification is
essential for surgical evacuation. Ice and elevation are supportive but not definitive, and delaying
treatment can be life-threatening.

, Q5 ANALYZE COMPLEX MATERNAL AND FETAL ASSESSMENT DATA TO FORMULATE
NURSING DIAGNOSES AND INTERVENTIONS
According to current CDC guidelines, which of the following is the recommended
first-line oral antibiotic for the treatment of uncomplicated gonococcal infection in
a pregnant patient?
A. Azithromycin 1 g orally
B. Ceftriaxone 500 mg intramuscularly CORRECT
C. Cefixime 800 mg orally
D. Doxycycline 100 mg twice daily for 7 days
RATIONALE: The CDC STI guidelines recommend ceftriaxone 500 mg IM as first-line for
uncomplicated gonorrhea, even during pregnancy. Azithromycin may be added if chlamydial
infection is not excluded, but it is not primary for gonorrhea. Cefixime is no longer preferred due
to resistance. Doxycycline is contraindicated in pregnancy.
Q6 ANALYZE COMPLEX MATERNAL AND FETAL ASSESSMENT DATA TO FORMULATE
NURSING DIAGNOSES AND INTERVENTIONS
A patient with preeclampsia is receiving magnesium sulfate. Which finding
indicates magnesium toxicity and requires immediate intervention?
A. Deep tendon reflexes 2+
B. Respiratory rate of 12 breaths per minute CORRECT
C. Urine output of 30 mL per hour
D. Serum magnesium level of 6.2 mEq/L
RATIONALE: Magnesium toxicity is indicated by respiratory depression (RR <12), loss of deep
tendon reflexes, and oliguria. A respiratory rate of 12 is borderline but indicates early depression;
the nurse should intervene to prevent further decline. DTRs 2+ are normal, urine output 30 mL/hr
is adequate, and a magnesium level of 6.2 mEq/L is within therapeutic range (4-7 mEq/L).
