Resource Title: OB HESI EXAM SUMMER 2024 HESI OB EXAM – GRADE A+ LATEST UPDATE
Subject Area: Obstetric Nursing & Maternal-Newborn Pharmacology
Exam Version: 2026-2027 Professional Update Exam Series
Format: Multiple Choice Questions (MCQ) with Complete Explanatory Rationales
Target Audience: Nursing Students, HESI OB Candidates, NCLEX-RN Candidates
STUDY WORKBOOK OUTLINE & OBJECTIVES
This study guide is systematically organized into four core nursing areas to ensure thorough preparation:
• Topic 1: Antepartum & Prenatal Care: Screening tests (MSAFP, TORCH, glucose trials), maternal
physiological changes, nutritional guidance (Vitamin B12, folic acid), and high-risk antepartum bleeding.
• Topic 2: Intrapartum & Labor Management: Labor stages, electronic fetal monitoring (variable
decelerations), medication infusion calculations, and management of rapid/precipitous deliveries.
• Topic 3: Postpartum Care & Maternal Complications: Prevention of hemorrhage, uterine massage,
postpartum depression risk stratification, and magnesium sulfate toxicology.
• Topic 4: Newborn Assessment & Neonatal Care: APGAR scoring, neonatal thermoregulation (cold stress),
neonatal prophylactic care (Vitamin K, Erythromycin), and high-risk newborn isolation.

TOPIC 1: ANTEPARTUM & PRENATAL CARE
Question 1: A client at 34 weeks gestation comes to the birthing center complaining of vaginal bleeding
that began one hour ago. The nurse's assessment reveals approximately 30 mL of bright red vaginal
bleeding, a fetal heart rate of 130-140 beats per minute, no uterine contractions, and no complaints of
pain or abdominal tenderness. What is the most likely cause of this client's bleeding?
A. Abruptio Placentae
B. Placenta Previa
C. Cervical laceration
D. Normal onset of labor
ANSWER : B — Placenta Previa
Explanation: Placenta Previa is characterized by painless, bright red vaginal bleeding in the third trimester.
Because the bleeding is painless and there are no uterine contractions or tenderness, this classic presentation
separates it from abruptio placentae (which is characterized by painful, dark red bleeding and uterine rigidity).
Cervical lacerations and normal labor onset do not typically present with 30 mL of bright red blood without
contractions or pain.
Question 2: A client at 30 weeks gestation reports that she has not felt her baby move in the last 24
hours. Concerned, she arrives in a panic at the obstetric clinic and is immediately sent to the hospital.
Which assessment finding warrants immediate intervention by the nurse?
A. Fetal heart rate of 140 beats per minute
B. Maternal blood pressure of 118/74 mmHg
C. Fetal heart rate of 60 beats per minute
D. Irregular Braxton Hicks contractions
ANSWER : C — Fetal heart rate of 60 beats per minute
Explanation: A fetal heart rate (FHR) of 60 beats per minute represents severe bradycardia (normal FHR is
110-160 bpm) and is a clear indicator of acute fetal distress or impending demise, requiring immediate emergency
intervention. An FHR of 140 bpm, normal blood pressure, and Braxton Hicks contractions are reassuring or
normal findings.

Question 3: A primigravida at 36 weeks gestation who is Rh-negative experiences mild abdominal
trauma in a motor vehicle collision. Which assessment finding is most important for the nurse to report
to the health care provider immediately?
A. Maternal heart rate of 92 beats per minute
B. Mild contractions occurring every 10 minutes
C. Absence of vaginal bleeding
D. Presence of normal fetal movement
ANSWER : B — Mild contractions occurring every 10 minutes
Explanation: Mild contractions every 10 minutes following abdominal trauma are highly concerning. In an
Rh-negative primigravida, even minor trauma can cause placental abruption or fetomaternal hemorrhage, which
can stimulate contractions and cause maternal sensitization to Rh-positive fetal blood. Reporting contractions is
critical so that uterine activity, fetal well-being, and the potential need for Rh immune globulin (RhoGAM) and a
Kleihauer-Betke test can be evaluated.
Question 4: A new mother who is a lacto-ovo vegetarian plans to breastfeed her infant. Which essential
nutrition information should the nurse provide to the mother prior to discharge?
A. Continue prenatal vitamins with B12 while breastfeeding
B. Supplement the breastfed infant with iron drops from birth
C. Discontinue all vitamin supplements and consume more dairy
D. Limit protein intake to prevent infant colic
ANSWER : A — Continue prenatal vitamins with B12 while breastfeeding
Explanation: Lacto-ovo vegetarians eat dairy and eggs but avoid meat, which can limit their intake of vitamin B12
(found primarily in animal meats). A breastfeeding mother on this diet must continue taking prenatal vitamins with
vitamin B12 to ensure her breast milk contains adequate levels, which are critical for the baby's neurological
development and red blood cell production.
