OB NURS 306 CERTIFICATION SCRIPT 2026
QUESTIONS WITH SOLUTIONS GRADED A+
◍ The umbilical vein carries _________.
Answer: Oxygen from the mother to the fetus
◍ A pregnant woman who has a history of cesarean births is requesting to have
a vaginal birth after cesarean (VBAC). In which of the following situations
should the nurse advise the patient that her request may be declined?a.
Transverse fetal lieb. Flexed fetal attitudec. Previous low flap uterine
incisiond. Positive vaginal candidiasis.
Answer: a.A baby in the transverse lie is lying sideways in the uterus. This
lie is incompatible physiologically with a vaginal delivery.b.A baby in the
flexed fetal attitude is in a physiologic position for a vaginal delivery.c.A
previous low flap uterine incision is not incompatible physiologically with a
vaginal delivery.d.A positive vaginal Candidiasis culture is not an indication
for cesarean birth.
◍ Depot medroxyprogestrone (Depo-Provera).
Answer: Class: Hormonal contraceptive (long-acting)Action: Alters cervical
and endometrial environment to prevent sperm penetration and egg
implantation. May also suppress ovulation.Therapeutic Use: Prevents
pregnancy and regulates menstrual cycle- progesterone only injection given
every 3 months- contains synthetic progesterone to suppress ovulation
◍ You are caring for a primiparous woman admitted to labor and delivery for
induction of labor at 42 weeks' gestation. She asks you to explain the factors
that contribute to prolonged labor. The best response would be to state the
following:a. Primiparous women are not at risk for dystocia because they
usually have small babies.b. Dystocia is related to uterine contractions, the
pelvis, the fetus, the position of the mother, and psychosocial response.c.
, Labor is primarily associated with pelvic abnormalities.d. Dystocia is
typically diagnosed prior to labor based on pelvimetry..
Answer: a.Dystocia is not exclusively related to fetal size and being
primiparous.b.This is the only correct definition of prolonged labor and
dystocia. The success of any labor depends on the complex interrelationship
of several factors: fetal size, presentation, position, size and shape of the
pelvis, and quality of uterine contractions.c.Pelvic abnormality is the least
important contributor to dystocia.d.Dystocia is diagnosed during, not prior
to, labor.
◍ A nurse is caring for a client who is receiving oxytocin (Pitocin) for
induction of labor and has an intrauterine pressure catheter (IUPC) placed to
monitor uterine contractions. For which of the following contraction
patterns should the nurse discontinue the infusion of oxytocin?a frequency
of every 2 minb. duration of 90 to 120 secondsc.intensity of 60 to 90 mm
Hgd. resting tone of 15 mm Hg.
Answer: a frequency of every 2 minb. duration of 90 to 120 secondsc.
intensity of 60 to 90 mm Hgd. resting tone of 15 mm HgA. INCORRECT:
This contraction pattern does not require discontinuing the infusion of
oxytocin.B. CORRECT: Oxytocin is discontinued if uterine
hyperstimulation occurs with a contraction duration longer than 90
seconds.C. INCORRECT: This contraction pattern does not require
discontinuing the infusion of oxytocin.D. INCORRECT: This contraction
pattern does not require discontinuing the infusion of oxytocin.
◍ The perinatal nurse caring for a laboring woman who is receiving an
oxytocin infusion documents the following information: rate of
__________, frequency and strength of __________, fetal __________, and
cervical __________ and __________..
Answer: ANS: infusion; contractions; heart rate; dilatation;
effacementOxytocin protocols in many institutions require that the nurse
remain at the patient's bedside at all times for careful surveillance. The
following data should be placed on a flow sheet in the patient record:
patient's vital signs, fetal heart rate, frequency, duration and strength of
, contractions, cervical effacement and dilatation, fetal station and lie, rate of
oxytocin infusion intake and urine output, and the psychological response of
the patient
◍ A nurse is teaching a client about the importance of primary health
prevention strategies in reproductive care. Which of the following primary
strategies should the nurse recommend?.
Answer: - HPV immunization- smoking cessation
◍ Phenylketonuria (PKU).
Answer: - hereditary conditions that causes the body to accumulate
phenylalanine (an amino acid)- metabolic inborn defect- severely
intellectually disabled without therapy- infant will be placed on a closely
monitored phenylalanine restricted diet
◍ Severe maternal morbidity (SMM).
Answer: - unintended and serious complication that occurs during labor,
birth, or postpartum that may lead to deathEXAMPLE:- postpartum
hemorrhage- amniotic fluid embolism- sepsis- acute renal failure-
eclampsia- cardiac arrest
◍ A nurse is caring for a client who is in labor and experiencing incomplete
uterine relaxation between hypertonic contractions. The nurse should
identify that this contraction pattern increases the risk for which of the
following complications?A) Prolonged laborB)Reduced fetal oxygen
supplyC)Delayed cervical dilationD) increased maternal stress.
Answer: A) Prolonged laborB)Reduced fetal oxygen supplyC)Delayed
cervical dilationD) increased maternal stress
◍ Your patient is a 28-year-old gravida 2 para 1 in active labor. She has been
in labor for 12 hours. Upon further assessment, the nurse determines that she
is experiencing a hypotonic labor pattern. Possible maternal and fetal
implications from hypotonic labor patterns are:a. Intrauterine infection and
maternal exhaustion with fetal distress usually occurring early in labor.b.
Intrauterine infection and maternal exhaustion with fetal distress usually
occurring late in labor.c. Intrauterine infection and postpartum hemorrhage
