OB MATERNITY HESI NEWEST 2024 VERSION 4 COMPLETE ALL 160 QUESTIONS AND CORRECT DETAILED
ANSWERS
Which position would the nurse instruct the patient to assume during labor to promote fetal
oxygenation? - (answer) Lateral
Which statement demonstrates the physiologic change that must occur in the uterus to preserve the
cervical changes during labor? - (answer) The myometrial cells become longer with each contraction
Muscle cells in the uterus remain shorter at the end of a contraction
Which physiologic change is associated with an increased risk for peripartum venous thrombosis? -
(answer) Increased number of clotting factors
Rationale: fibrinolysis decreases during labor to promote coagulation at the placental site, and the
increase in clotting factors raises the mothers risk for venous thrombosis during and after pregnancy.
which intervention would the nurse choose to facilitate the process of labor for a pt who is 6cm dilated
and 100% effaced, at 1+ station, contracting every 4 mins, and has a pain rating of 6/10? - (answer)
Assisting the pt in relaxing
Rationale: maternal catecholamines are secreted in response to anxiety and fear and can inhibit uterine
contractility and placental blood flow. However, relaxation augments the natural process of labor.
Which physiologic change would the nurse anticipate in the active phase of labor - (answer) Internal
fetal rotation
Rationale: transitional phase: maternal tremors, complete cervical dilation; second stage of labor:
involuntary pushing response
which change in the intensity of the uterine tone during the interval period of a contraction pattern
occurs during labor? - (answer) relaxed
,OB MATERNITY HESI NEWEST 2024 VERSION 4 COMPLETE ALL 160 QUESTIONS AND CORRECT DETAILED
ANSWERS
rationale: the uterine muscle would be relaxed during the interval period of a uterine contraction. the
interval period is also known as the resting tone. During this period, most fetal exchange of oxygen,
nutrients, and waste products occurs.
which statement describes a fetal protective mechanism that allows for tolerance of interrupted blood
supply during a contraction? SATA - (answer) The fetal cardiac output is high
the fetal hematocrit is elevated
fetal hemoglobin more readily takes on oxygen
carbon dioxide is easily released from the hemoglobin
rationale: the placental circulation usually has a high enough reserve over the fetal base needs to
tolerate the intermittent interruption of blood flow. an elevated FHR is not intended to be a protective
mechanism that allows for the tolerance of interrupted blood supply during a contraction.
which info about the amniotic fluid would the nurse include in a documented summary for a pt with
ruptured amniotic membranes? SATA - (answer) Time
odor
color
clarity
amount
based on the pt's history, for which complication would the nurse anticipate monitoring?

ANSWERS
Assessment data:
39 weeks gestation
gravida 9, para 6
1 spontaneous abortion
1 elective termination - (answer) Postpartum hemorrhage
Rationale: the pt has a high parity. a parity of 5 or more is associated with a risk of postpartum
hemorrhage. women who have had several spontaneous abortions or who have given birth to infants
with abnormalities may have an increased risk for having an infant with a birth defect. the pt is not at
risk for prolonged labor or placental abruption.
what change has occurred in the cervix of a pt 10cm dilated and 100% effaced? - (answer) the cervix
merges with the lower uterine segment
rationale: the cervix merges with the lower uterine segment when it is 100% effaced; therefore, it will
lose the characteristic of a distinct cylindrical structure. the cervix is not a muscle that pushes the fetus
into the birth canal. the cervis is drawn up into the body of the lower uterine segment, allowing for the
passage of the baby into the birth canal. the cervix does not create opposing contractions with the upper
uterine segment.
which initial assessment would the nurse perform on a laboring pt who is 5cm dilated, 80% effaced, at
1+ station, and thinks her water broke? - (answer) auscultating fetal heart rate tones
rationale: b/c of the risk for cord prolapse or cord compression, the RN would assess the FHR for 1
minute after the membranes rupture. the color of the fluid, the estimated amount of amniotic fluid, and
the maternal temperature can be evaluated after the FHR.
which info would the nurse include in the teaching of a multiparous pt at 39 weeks of gestation who is
being discharged howe after it is determined that she is not in labor? - (answer) Call your HCP if the
baby does not move as frequently
