ANS: C During labor contractions, the maternal blood supply to the placenta gradually stops as thespiral arteries supplying the intervillous space are compressed by the contracting uterine muscle. The maternal blood supply to the placenta gradually stops with contractions and the exchange of oxygen and waste products decreases.

A student nurse is trying to assess vital signs on a laboring woman. Which statement by theregistered nurse is the best rationale for assessing maternal vital signs between contractions? a. During a contraction, assessing fetal heart rates is the priority. b. Maternal circulating blood volume increases temporarily during contractions. c. Maternal blood flow to the heart is reduced during contractions. d. Vital signs taken during contractions are not accurate. ANS: B During uterine contractions, blood flow to the placenta temporarily stops, causing a relative increase in the mother’s blood volume, which in turn temporarily increases blood pressure andslows pulse. It is important to monitor fetal response to contractions, but the question is concerned with the maternal vital signs so assessing the fetal heart rate is not the priority. Vitalsigns are altered by contractions but are considered accurate for that period of time. However,they do not reflect the woman’s baseline.
