CORRECT SOLUTIONS 2026
⩥ 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
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?
, 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.
