Which mechanism of labor occurs when the largest diameter of the fetal presenting part passes the pelvic inlet? a. Engagement b. Extension c. Internal rotation d. External rotation - ANS-Engagement To adequately care for patients, the nurse understands that labor contractions facilitate cervical dilation by a. contracting the lower uterine segment. b. enlarging the internal size of the uterus. c. promoting blood flow to the cervix. d. pulling the cervix over the fetus and amniotic sac. - ANS-pulling the cervix over the fetus and amniotic sac. A student asks how pregnant women can usually tolerate the normal blood loss associated with childbirth. Which response by the nurse is best? "It is because they have a. a higher hematocrit." b. increased blood volume." c. a lower fibrinogen level." d. increased leukocytes." - ANS-increased blood volume. To assess the duration of labor contractions, the nurse determines the time a. from the beginning of one contraction to the beginning of the next. b. from the beginning to the end of each contraction. c. of the strongest intensity of each contraction. d. of uterine relaxation between two contractions. - ANS-from the beginning to the end of each contraction The nurse teaching a prenatal class explains that which is the best indicator of true labor? a. Bloody show b. Cervical dilation and effacement c. Fetal descent into the pelvic inlet d. Uterine contractions every 7 minutes - ANS-Cervical dilation and effacement The student nurse learns that which factor ensures that the smallest anteriorposterior diameter of the fetal head enters the pelvis? a. Descent b. Engagement c. Flexion d. Station - ANS-flexion What results from the adaptation of the fetus to the size and shape of the pelvis? a. Lightening b. Lie c. Molding d. Presentation - ANS-molding The nurse assesses a patient whose cervix is dilated to 5 cm. What phase of labor does the nurse recognize the woman to be in? a. Latent phase b. Active phase c.

Bloody show b. False labor c. Lightening d. Bladder distention - ANS-Bloody show The nurse is caring for a woman whose fetus has a breech presentation. What complication does the nurse prepare to assist with? a. Umbilical cord compression b. More rapid labor c. A high risk of infection d. Maternal perineal trauma - ANS-Umbilical cord compression The primary difference between the labor of a nullipara and that of a multipara is the a. amount of cervical dilation. b. total duration of labor. c. level of pain experienced. d. sequence of labor mechanisms. - ANS-total duration of labor. Which maternal factor may inhibit fetal descent and require further nursing interventions? a. Decreased peristalsis b. A full bladder c. Reduction in internal uterine size d. Rupture of membranes - ANS-a full bladder Leopold's maneuvers are used by practitioners to determine a. the best location to assess the fetal heart rate (FHR). b. cervical dilation and effacement. c. whether the fetus is in the posterior position. d. if the woman needs an amniotomy. - ANS-the best location to assess the fetal heart rate (FHR)...
