A primigravida at 39 weeks of gestation is observed for 2 hours in the intrapartum unit. The fetal heart rate has been normal. Contractions are 5 to 9 minutes apart, 20 to 30 seconds in duration, and of mild intensity. Cervical dilation is 1 to 2 cm and uneffaced (unchanged from admission). Membranes are intact. The nurse should expect the woman to be:a. admitted and prepared for a cesarean birth.b. admitted for extended observation.c. discharged home with a sedative.d. discharged home to await the onset of true labor.
In relation to primary and secondary powers, the maternity nurse comprehends that:a. primary powers are responsible for effacement and dilation of the cervix.b. effacement generally is well ahead of dilation in women giving birth for the first time; they are closer together in subsequent pregnancies.c. scarring of the cervix caused by a previous infection or surgery may make the delivery a bit more painful, but it should not slow or inhibit dilation.d. pushing in the second stage of labor is more effective if the woman can breathe deeply and control some of her involuntary needs to push, as the nurse directs.
19. The perinatal nurse is giving discharge instructions to a woman after suction curettage secondary to a hydatidiform mole. Thewoman asks why she must take oral contraceptives for the next 12 months. The best response from the nurse would be:a. "If you get pregnant within 1 year, the chance of a successful pregnancy is verysmall. Therefore, if you desire a future pregnancy, it would be better for you touse the most reliable method of contraception available."b. "The major risk to you after a molar pregnancy is a type of cancer that can bediagnosed only by measuring the same hormone that your body produces duringpregnancy. If you were to get pregnant, it would make the diagnosis of this cancermore difficult."c. "If you can avoid a pregnancy for the next year, the chance of developing asecond molar pregnancy is rare. Therefore, to improve your chance of asuccessful pregnancy, it is better not to get pregnant at this time."d. "Oral contraceptives are the only form of birth control that will prevent arecurrence of a molar pregnancy."

With regard to factors that affect how the fetus moves through the birth canal, nurses should be aware that:a. the fetal attitude describes the angle at which the fetus exits the uterus.b. of the two primary fetal lies, the horizontal lie is that in which the long axis of the fetus is parallel to the long axis of the mother.c. the normal attitude of the fetus is called general flexion.d. the transverse lie is preferred for vaginal birth.
The nurse has received report regarding her patient in labor. The woman's last vaginal examination was recorded as 3 cm, 30%, and -2. The nurse's interpretation of this assessment is that:a. the cervix is effaced 3 cm, it is dilated 30%, and the presenting part is 2 cm above the ischial spines.b. the cervix is 3 cm dilated, it is effaced 30%, and the presenting part is 2 cm above the ischial spines.c. the cervix is effaced 3 cm, it is dilated 30%, and the presenting part is 2 cm below the ischial spines.d. the cervix is dilated 3 cm, it is effaced 30%, and the presenting part is 2 cm below the ischial spines.
