Which statement is the best rationale for assessing maternal vital signs between contrac-tions?
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.
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 and slows the pulse.
It is important to monitor fetal response to contractions, but the question is concerned with the maternal vital signs.
Maternal blood flow is increased during a contraction.
Vital signs are altered by contractions but are considered accurate for a period of time.
