Ch. 15 Flashcards
Fetal assessment (42 cards)
Fetal bradycardia is most common during
Prolonged umbilical cord compression
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 nurses first priority is to
Change the womans position
The nurse caring for the laboring woman should understand that early decelerations are caused by
Altered fetal cerebral blood flow
The nurse providing care for the laboring woman comprehends that accelerations with fetal movement
Are reassuring
The nurse providing care for the laboring woman realizes that variable fetal heart rate (FHR) decelerations are caused by
Umbilical cord compression
The nurse providing care for the laboring woman should understand that late fetal heart rate (FHR) decelerations are the result of
Uteroplacental insufficiency
The nurse providing care for the laboring woman should understand that amnioinfusion is used to treat
Variable decelerations
The nurse caring for the woman in labor should understand that maternal hypotension can result in
Uteroplacental insufficiency
The nurse caring for a laboring woman is aware that maternal cardiac output can be increased by
Change in position
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 at the onset of several contractions and returns to baseline before each contraction ends. The nurse should
Document the finding in the clients record
Which fetal heart rate (FHR) finding would concern the nurse during labor
Late decelerations
The most common cause of decreased variability in the fetal heart rate (FHR) that lasts 30 minutes or less is
Fetal sleep cycles
The baseline fetal heart rate (FHR) is the average rate during a 10-minute segment. Changes in FHR are categorized as periodic or episodic. These patterns include both accelerations and decelerations. The labor nurse is evaluating the patients most recent 10-minute segment on the monitor strip and notes a late deceleration. This is likely to be caused by which physiologic alteration
Placental abruption
Maternal supine hypotension
A tiered system of categorizing FHR has been recommended by regulatory agencies. Nurses, midwives, and physicians who care for women in labor must have a working knowledge of fetal monitoring standards and understand the significance of each category. These categories include
Category I
Category II
Category III
Increasing the infusion rate of nonadditive intravenous fluids can increase fetal oxygenation primarily by
Expanding maternal blood volume
Why is continuous electronic fetal monitoring usually used when oxytocin is administered?
Uteroplacental exchange may be compromised
The nurse knows that proper placement of the tocotransducer for electronic fetal monitoring is located
Over the uterine fundus
Which maternal condition is considered a contraindication for the application of internal monitoring devices
Unruptured membranes
The uterine contractions of a woman early in the active phase of labor are assessed by an internal uterine pressure catheter (IUPC). The nurse notes that the intrauterine pressure at the peak of the contraction ranges from 65 to 70 mm Hg and the resting tone range is 6 to 10 mm Hg. The uterine contractions occur every 3 to 4 minutes and last an average of 55 to 60 seconds. On the basis of this information, the nurse should
Document the findings because they reflect the expected contraction pattern for the active phase of labor
In assisting with the two factors that have an effect on fetal status (i.e., pushing and positioning), nurses should
Encourage the womans cooperation in avoiding the supine position
A nurse may be called on to stimulate the fetal scalp
To elicit an acceleration in the fetal heart rate (FHR)
The nurse caring for a woman in labor understands that prolonged decelerations
Usually are isolated events that end spontaneously
What correctly matches the type of deceleration with its likely cause
Late decelerationuteroplacental inefficiency
Which deceleration of the fetal heart rate would not require the nurse to change the maternal position
Early decelerations
