MATERNITY OB HESI EXAM VERSION ONE
(1) REVISED AND UPDATED IN 2025-2026
QUESTIONS AND ANSWERS
• A client is admitted to the labor and delivery unit with
contractions that are 3-5 minutes apart, lasting 60-70 seconds.
She reports that she is leaking fluid. A vaginal exam reveals
that her cervix is 80 percent effaced and 4 cm dilated and a -1
station. The LPN/LVN knows that the client is in which phase
A) Latent phase, First Stage
and stage of labor?
B) Active Phase of First Stage
C) Latent phase of Second Stage
D) Transition
,Ans:
B) Active Phase of First Stage
Second stage = full dilation
until birth
• To assess uterine contractions the LPN/LVN would
A) Asses duration from the beginning of the contraction to
the peak of the same contraction, frequency by
measuring the time between the beginning of one
contraction to the beginning of the next contraction.
B) Assess frequency as the time between the end of one
contraction and the beginning of the next contraction,
duration as the length of time from the beginning to the
end of contractions, and palpate the uterus for strength
C) Assess duration from beginning to end of each
contraction. Assess the strength of the contraction by the
external fetal monitor reading. Measure frequency by
measuring the beginning of one contraction to another.
D) Assess duration from beginning to end of each
contraction., frequency by measuring the time between the
beginnings of
,contractions, and palpate the fundus of the uterus for
strength.
Ans:
D) Assess duration from beginning to end of each
contraction., frequency by measuring the time
between the beginnings of contractions, and palpate
the fundus of the uterus for strength.
• During labor a fetus with an average heart rate of 175
beats/min over a 15-minute period would be considered
to have: A) A normal baseline heart rate. B) Bradycardia.
C) Hypoxia.
D) Tachycardia
.
Ans:
D) Tachycardia.
• As a perinatal LPN/LVN you realize that a fetal heart rate
that is tachycardic, is bradycardic, or has late decelerations
with loss of variability is nonreassuring and is associated
with
A) Cord compression
, B) Hypotension
C) Hypoxemia/acidemia
D) Maternal drug use. Ans:
C) Hypoxemia/acidemia
• The LPN/LVN providing care for the laboring woman
should understand that amnioinfusion is used to treat:
A) Fetal tachycardia.
B) Fetal bradycardia.
C) Variable decelerations
D) Late decelerations. Ans: C) Variable decelerations
• The most common cause of decreased variability in the fetal
heart rate (FHR) that lasts 30 minutes or less is:
A) Fetal hypoxemia
B) Fetal sleep cycles
C) Altered cerebral blood flow.
D) Umbilical cord compression. Ans:
B) Fetal sleep cycles
• While evaluating an external monitor tracing of a woman
in active labor whose labor is being induced, the nurse notes
that the fetal heart rate (FHR) begins to decelerate in a slow
