This 55-question HESI OB/Maternity Version 1 (V1) exam preparation guide provides comprehensive coverage
of antepartum, intrapartum, postpartum, and newborn nursing care aligned with 2026/2027 ACOG and
AWHONN standards. Each question includes a detailed rationale explaining the correct answer, why each
distractor is wrong, and the maternal-fetal physiology and nursing priorities behind the answer—designed to
deliver verified, exam-ready A+ preparation.
Section 1: Antepartum Assessment and Prenatal Care (Q1-8)
GTPAL, prenatal visits, maternal adaptations (cardiovascular, respiratory, GI), and nutrition.
Section 2: Complications of Pregnancy (Q9-17)
Hypertensive disorders (preeclampsia, eclampsia, HELLP), diabetes, bleeding disorders, and infections.
Section 3: Intrapartum Care and Fetal Monitoring (Q18-28)
Stages of labor, FHR baseline/variability/decelerations, and pain management.
Section 4: Postpartum Assessment and Complications (Q29-37)
BUBBLE-HE, involution, lochia, postpartum hemorrhage, endometritis, mastitis, DVT.
Section 5: Newborn Assessment and Care (Q38-45)
APGAR, transition, feeding, jaundice, hypoglycemia, RDS, and sepsis.
Section 6: High-Risk Pregnancy and Perinatal Emergencies (Q46-50)
Preterm labor, PROM/PPROM, cord prolapse, shoulder dystocia, and amniotic fluid embolism.
Section 7: Obstetric Pharmacology and Professional Practice (Q51-55)
Oxytocin, magnesium sulfate, Rhogam, terbutaline, and culturally responsive family-centered care.
Cognitive Level Distribution
Recall (30%) — Direct identification of definitions, calculations, and key concepts (GTPAL, Naegele's rule,
APGAR).
Application (50%) — Clinical scenarios requiring nursing intervention and prioritization.
Analysis (20%) — Fetal monitoring strip interpretation, complication differentiation, and clinical judgment.
How to Read Each Question
Each question presents a stem, four options (A-D), and a rationale. The correct option is marked [CORRECT] in
green, and the explicit Correct Answer line follows. Rationales explain the OB/maternity nursing reasoning,
maternal-fetal physiology, pharmacological principles, and clinical priorities—with verified tips to reinforce the most
commonly tested concepts on the HESI OB/Maternity V1 exam.

SECTION 1: Antepartum Assessment and Prenatal Care (Q1-8)
GTPAL, prenatal visits, maternal adaptations (cardiovascular, respiratory, GI), and nutrition.
Q1.
A client's LMP began on March 10. Using Naegele's rule, what is the estimated date of delivery (EDD)?
A. December 17. [CORRECT]
B. December 10.
C. November 17.
D. January 17.
Correct Answer: A — December 17.
Rationale: Naegele's rule = LMP first day + 7 days, subtract 3 months, add 1 year. March 10 + 7 days = March
17; subtract 3 months = December 17. Option B omits the +7 days; option C subtracts 4 months; option D adds
a month instead of subtracting. Verified tip: 'plus 7, minus 3' is the Naegele mnemonic.
Q2.
A client reports she is currently 16 weeks pregnant. She has had two prior term deliveries, one preterm delivery at
35 weeks, and one miscarriage at 8 weeks. All living children are alive. What is her correct GTPAL?
A. G4 T2 P1 A1 L3. [CORRECT]
B. G4 T1 P2 A1 L3.
C. G3 T2 P1 A1 L3.
D. G4 T2 P1 A0 L3.
Correct Answer: A — G4 T2 P1 A1 L3.
Rationale: GTPAL: G = total pregnancies = 4 (current + 2 term + 1 preterm + 1 miscarriage); T = term births
≥37 weeks = 2; P = preterm births 20–36 weeks = 1; A = abortions/miscarriages <20 weeks = 1; L = living
children = 3. Option B misclassifies term/preterm; option C miscounts gravidity (current pregnancy counts);
option D omits the miscarriage in 'A.' Verified tip: every pregnancy counts in G, including the current one.
Q3.
At 24 weeks' gestation, a nurse measures fundal height at 20 cm. The client is certain of her LMP. Which
interpretation is most accurate?
A. Fundal height is below expected; notify the provider to evaluate for intrauterine growth
restriction, oligohydramnios, or incorrect fetal position. [CORRECT]
B. Fundal height is normal for 24 weeks; document and continue routine care.
C. Fundal height suggests multifetal gestation; prepare for ultrasound.
D. Fundal height indicates polyhydramnios; restrict fluids.
Correct Answer: A — Fundal height is below expected; notify the provider to evaluate for intrauterine
growt...
Rationale: From 20–36 weeks, fundal height in cm should approximate gestational age ±2 cm. At 24 weeks, 20
cm is >2 cm below expected, suggesting intrauterine growth restriction, oligohydramnios, fetal anomaly, or
incorrect position; provider notification for ultrasound is the priority. Option B normalizes an abnormal finding;
options C and D address the opposite (excess growth).
