OB EXAM 2 QUESTIONS AND ANSWERS 2026 |
VERIFIED A+ TEST BANK BUNDLE
This comprehensive exam preparation guide
contains 200 highly verified multiple-choice
questions with answers and rationales tailored
for the 2026 Obstetric (OB) Nursing Exam 2. It
covers high-yield maternal-newborn concepts,
including preeclampsia, labor stages, fetal
heart rate monitoring, postpartum
complications, and newborn assessments. Ideal
for nursing students aiming for an A+, this
resource ensures mastery of critical test bank
questions
1. A nurse is assessing a client at 34 weeks
gestation who presents with sudden, severe
abdominal pain and dark red vaginal bleeding.
The uterus is rigid and tender upon palpation.
Which complication should the nurse suspect?
A) Placenta previa
B) Abruptio placentae
C) Cervical insufficiency
D) Preterm labor
Answer: B) Abruptio placentae
Rationale: Abruptio placentae is the premature
separation of the placenta from the uterine wall,
classically presenting with painful, dark red
, vaginal bleeding and a rigid, board-like abdomen.
In contrast, placenta previa presents as painless,
bright red bleeding. Cervical insufficiency and
preterm labor do not typically cause a rigid,
painful uterus with dark bleeding.
2. A client with preeclampsia is receiving an
intravenous infusion of magnesium sulfate. Which
finding requires the nurse to immediately
discontinue the infusion and notify the provider?
A) Deep tendon reflexes of 2+
B) Urinary output of 40 mL over the past hour
C) Respiratory rate of 10 breaths per minute
D) A feeling of warmth and flushing
Answer: C) Respiratory rate of 10 breaths per
minute
Rationale: A respiratory rate below 12 breaths
per minute is a critical sign of magnesium sulfate
toxicity, indicating central nervous system
depression. Deep tendon reflexes of 2+ and urine
output above 30 mL/hr are normal/acceptable
findings. Flushing and warmth are expected side
effects of the medication, not signs of toxic
overdose.
3. The nurse notes a pattern of late decelerations
on the fetal monitor strip during active labor.
Which is the priority nursing action?
A) Place the client in a supine position
B) Increase the rate of the oxytocin infusion
, C) Administer oxygen via non-rebreather face
mask
D) Perform a vaginal examination to check for
dilation
Answer: C) Administer oxygen via non-rebreather
face mask
Rationale: Late decelerations indicate
uteroplacental insufficiency. Immediate
intrauterine resuscitation is required, which
includes administering oxygen (usually 8–10
L/min), turning the client to the lateral side to
relieve vena cava compression, and stopping
oxytocin. Placing the client supine worsen
baseline perfusion.
4. A nurse is preparing to administer Rh immune
globulin (RhoGAM) to a postpartum client. Which
laboratory result indicates the need for this
medication?
A) Mother is Rh-positive, newborn is Rh-negative
B) Mother is Rh-negative, newborn is Rh-positive
C) Mother is Rh-negative, newborn is Rh-negative
D) Mother is Rh-positive, newborn is Rh-positive
Answer: B) Mother is Rh-negative, newborn is Rh-
positive
Rationale: RhoGAM is administered to Rh-
negative mothers who give birth to Rh-positive
infants to prevent maternal sensitization to the
Rh antigen. This prevents hemolytic disease of
the newborn in future pregnancies. If the infant is
, Rh-negative, or if the mother is already Rh-
positive, RhoGAM is not indicated.
5. During a vaginal examination, the nurse notes
that the umbilical cord has prolapsed into the
vagina. Which action should the nurse take first?
A) Attempt to push the umbilical cord back into
the uterine cavity
B) Apply a sterile, ice-cold saline compress
directly to the cord
C) Use a sterile gloved hand to apply upward
pressure on the fetal presenting part
D) Instruct the client to perform the Valsalva
maneuver to expedite delivery
Answer: C) Use a sterile gloved hand to apply
upward pressure on the fetal presenting part
Rationale: The immediate priority for a prolapsed
cord is to relieve compression on the cord by
holding the fetal presenting part off of it until an
emergency Cesarean birth can be performed.
The cord should never be pushed back inside.
Cold compresses cause vasospasm, and pushing
maneuvers increase compression.
6. A client at 38 weeks gestation is admitted to the
labor unit. Her obstetric history includes a
miscarriage at 10 weeks, a birth at 35 weeks
(child living), and a birth at 39 weeks (child
living). Using the GTPAL system, how should the
nurse document her history?
