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. 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 contractions and returns to baseline before each contraction ends. The nurse should: A) Insert an internal monitor B) Document the finding in the client's record. C) Discontinue the oxytocin infusion D) Change the woman's position 12) What three measures should the nurse implement to provide intrauterine resuscitation? Select the response that best indicates the priority of actions that should be taken. A) Reposition the mother, increase intravenous (IV) fluid, and provide oxygen via face mask. B) Perform a vaginal examination, reposition the mother, and provide oxygen via face mask. C) Administer oxygen to the mother, increase IV fluid, and notify the care provider. D) Call the provider, reposition the mother, and perform a vaginal examination 13) When using intermittent auscultation (IA) to assess uterine activity, nurse should be aware that: A) The resting tone between contractions is described as either placid or turbulent B) The examiner's hand should be placed over the fundus before, during, and after contractions. C) The frequency and duration of contractions is measured in seconds for consistency D) Contraction intensity is given a judgment number of 1 to 7 by the nurse and client together. 14) Perinatal nurse are legally responsible for: A) Applying the external fetal monitor and notifying the care provider. B) Correctly interpreting fetal heart rate (FHR) patterns, initiating appropriate nursing interventions, and documenting the outcomes. C) Greeting the client on arrival, assessing her, and starting an intravenous line. D) Making sure that the woman is comfortable. 15) The nurse providing care for the laboring woman should understand that late fetal heart rate (FHR) decelerations are caused by: A) Altered cerebral blood flow B) Spontaneous rupture of membranes C) Uteroplacental insufficiency D) Umbilical cord compression 16) The nurse providing care for the laboring woman should understand that variable fetal heart rate (FHR) decelerations are caused by: A) Umbilical cord compression. B) Altered fetal cerebral blood flow C) Fetal hypoxemia. D) Uteroplacental insufficiency 17) Which of the following is NOT a reassuring component of the fetal heart rate A) FHR of 114 B) Accelerations of the FHR C) Moderate Variability D) Absent FHR Variability 18) You are evaluating the fetal monitor tracing of your client, who is in active labor. Suddenly you see the fetal heart rate (FHR) drop from its baseline of 125 down to 80. You reposition the mother, provide oxygen, increase intravenous (IV) fluid, and perform a vaginal examination. The cervix has not changed. Five minutes have passed, and the fetal heart rate remains in the 80s. What additional nursing measures should you take? A) Call for help and Notify the care provider immediately B) Start pitocin C) Have her empty her bladder D) Insert a Foley catheter 19) What is an advantage of external electronic fetal monitoring? A) Once correctly applied by the nurse, the transducer need not be repositioned even when the woman changes positions. B) The tocotransducer can measure and record the frequency, regularity, intensity, and approximate duration of uterine contractions (UCs). C) The external EFM does not require rupture of membranes or introduction of scalp electrode or IUPC which may introduce risk of infection or fetal scarring. D) The external EFM can accurately record FHR all the time. 20) A number of methods to assist in the assessment of fetal well-being have been developed for use in conjunction with electronic fetal monitoring. These various technologies assist in supporting interventions for a nonreassuring fetal heart rate pattern when necessary. The labor and delivery nurse should be aware that one of these modalities, fetal oxygen saturation monitoring, includes the use of: A) Fetal blood sampling B) Umbilical cord acid-base determination C) Fetal pulse oximetry. D) A fetal acoustic stimulator. 21) The nurse caring for the woman in labor should understand that maternal hypotension can result in: A) Uteroplacental insufficiency. B) Spontaneous rupture of membranes C) Fetal dysrhythmias. D) Early decelerations. 22) The nurse providing care for the laboring woman should understand that accelerations with fetal movement: A) Are caused by umbilical cord compression B) Are caused by uteroplacental insufficiency C) Warrant close observation D) Are reassuring.
