a Lithotomy c Sitting b Kneeling d Walking ANS: A The predominant position in the United States for physician-attended births is the lithotomy position, which requires a woman to be in a reclined position with her legs in stirrups Gravity has little effect in this position Kneeling, sitting, and walking help align the fetus with the pelvic outlet and allow gravity to assist in fetal descent PTS: DIF: Cognitive Level: Analysis REF: 385, 386 Mosby items and derived items © 2010, 2006, 2002 by Mosby, Inc., an affiliate of Elsevier Inc Test Bank 15-3 OBJ: Client Needs: Health Promotion and Maintenance TOP: Nursing Process: Planning, Implementation Which position would the nurse suggest for second-stage labor if the pelvic outlet needs to be increased? a Semirecumbent c Squatting b Sitting d Side-lying ANS: C The squatting position may help increase the pelvic outlet Kneeling or squatting moves the uterus forward and aligns the fetus with the pelvic inlet; this can facilitate the second stage of labor by increasing the pelvic outlet PTS: DIF: Cognitive Level: Comprehension OBJ: Client Needs: Health Promotion and Maintenance TOP: Nursing Process: Implementation REF: 385 To adequately care for a laboring woman, the nurse knows that which stage of labor varies the most in length? a First c Third b Second d Fourth ANS: A The first stage of labor is considered to last from the onset of regular uterine contractions to full dilation of the cervix The first stage is much longer than the second and third stages combined In a first-time pregnancy the first stage of labor can take up to 20 hours The second stage of labor lasts from the time the cervix is fully dilated to the birth of the fetus The average length is 20 minutes for a multiparous woman and 50 minutes for a nulliparous woman The third stage of labor lasts from the birth of the fetus until the placenta is delivered This stage may be as short as minutes or as long as hour The fourth stage of labor, recovery, lasts about hours after delivery of the placenta PTS: DIF: Cognitive Level: Knowledge OBJ: Client Needs: Health Promotion and Maintenance TOP: Nursing Process: Planning REF: 387, 388 The nurse would expect which maternal cardiovascular finding during labor?
