,Section A - Antepartum Assessment AND CARE
Q1.
A patient with a history of prior cesarean birth presents in active labor. The provider
orders a trial of labor after cesarean (TOLAC). Which finding would be an absolute
contraindication to continuing TOLAC?
A. Previous low-transverse uterine incision B. Fetal heart rate with moderate variability
and accelerations
C. Nonreassuring fetal status with a D. Cervical dilation of 6 cm with adequate
Category III tracing contractions
Correct: C - Nonreassuring fetal status with a Category III tracing
Rationale:A Category III fetal heart tracing indicates fetal compromise and requires
immediate delivery, making TOLAC contraindicated. A prior low-transverse incision is a
standard indication for TOLAC. Moderate variability with accelerations is reassuring.
Adequate dilation with contractions is expected in active labor.
Q2.
Which physiological adaptation in the pregnant patient creates a predisposition to supine
hypotension syndrome, and what is the primary compensatory mechanism?
A. Aortocaval compression by the gravid B. Decreased venous return due to
uterus; compensatory increase in cardiac progesterone-induced vasodilation;
output via sympathetic stimulation compensatory peripheral vasoconstriction
C. Increased blood volume; compensatory D. Elevated diaphragm; compensatory
renal sodium retention tachypnea
Correct: A - Aortocaval compression by the gravid uterus; compensatory increase in
cardiac output via sympathetic stimulation
Rationale:In supine position, the gravid uterus compresses the inferior vena cava and aorta,
reducing venous return and cardiac output. The body compensates via sympathetic
activation, increasing heart rate and systemic vascular resistance. Progesterone-induced
vasodilation contributes to blood pressure changes but is not the primary cause. Increased
blood volume and elevated diaphragm are not directly related to supine hypotension.
Q3.
A patient at 28 weeks gestation with severe preeclampsia is receiving magnesium sulfate.
Which assessment finding indicates magnesium toxicity that requires immediate
intervention?
Page 3
, Section A - Antepartum Assessment AND CARE
A. Respiratory rate of 12 breaths/min and B. Urine output of 40 mL/hr and mild
absent deep tendon reflexes headache
C. Blood pressure of 150/95 mm Hg and 2+ D. Fetal heart rate of 140 bpm with
proteinuria moderate variability
Correct: A - Respiratory rate of 12 breaths/min and absent deep tendon reflexes
Rationale:Magnesium toxicity causes respiratory depression (RR <12) and loss of deep
tendon reflexes. This requires immediate discontinuation of magnesium and administration of
calcium gluconate. Urine output >30 mL/hr is acceptable. Elevated BP and proteinuria are
signs of preeclampsia, not magnesium toxicity. Fetal heart rate is reassuring.
Q4.
A patient in active labor has ruptured membranes and the fetus is in occiput posterior
position. Which nursing intervention is most likely to facilitate fetal rotation and labor
progress?
A. Encouraging the patient to lie supine with B. Instructing the patient to assume a
knees flexed hands-and-knees position
C. Applying fundal pressure during D. Administering oxytocin to augment
contractions contractions
Correct: B - Instructing the patient to assume a hands-and-knees position
Rationale:Hands-and-knees position uses gravity and pelvic mobility to encourage rotation of
the fetus from occiput posterior to anterior. Supine positioning may worsen malposition.
Fundal pressure is not recommended and can cause fetal injury. Oxytocin augments
contractions but does not promote rotation.
Q5.
A nurse is interpreting a fetal heart rate tracing. The baseline is 140 bpm, variability is
minimal, and there are recurrent late decelerations. According to NICHD terminology, how
should this tracing be categorized, and what is the initial nursing action?
A. Category I; continue to monitor and B. Category II; reposition the patient and
document administer oxygen
C. Category III; prepare for immediate D. Category II; notify the provider and
cesarean birth consider amnioinfusion
Correct: B - Category II; reposition the patient and administer oxygen
