OB HESI 2021 Practice Questions Set 2 WITH
VERRIFIED ANSWERS
1) 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 nurse knows that the client is in which phase and stage of labor?
A) Latent phase, First Stage
B) Active Phase of First
Stage
C) Latent phase of Second Stage
D) Transition
2) To assess uterine contractions the nurse 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.
3) Which basic type of pelvis includes the correct description and percentage of occurrence in women?
A) Platypelloid: flattened, wide, shallow; 3%
B) Anthropoid: resembling the ape; narrower; 10%
C) Android: resembling the male; wider oval;
15% Gynecoid: classic female; heart shaped; 75%
4) What position would be least effective when gravity is desired to assist in fetal descent?
A) Lithotomy
B) Walking
C) Kneeling
D) Sitting
5) The factors that affect the process of labor and birth, known commonly as the five Ps, include all EXCEPT:
A) Passageway.
B) Powers.
C) Passenger.
D) Pressure.
, 2
The 5 P's are:
1. Powers (contractions). 2. Passengers (fetus and placenta). 3. Passageway (birth canal).
4. Position (of the mother). 5. Psychological Response
6) While evaluating an external monitor tracing of a woman in active labor, the nurse notes that the fetal
heart rate (FHR) for five sequential contractions begins to decelerate late in the contraction, with the nadir of
the decelerations occurring after the peak of the contraction. The nurse first priority is to:
A) Notify the care provider.
B) Assist with amnioinfusion
C) Change the woman's position
D) Insert a scalp electrode.
7) 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.
Normal FHR: 110-160
8) As a perinatal nurse 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.
Late decels are associated with poor placenta perfusion.
9) The nurse 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.
10) 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. The fetus sleeps in 20-30 cycles
C) Altered cerebral blood flow.
D) Umbilical cord compression.
11) 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 curve at the onset of several
