To Assess the Health of the Mother Accurately During Labor

To assess the health of the mother accurately during labor, the nurse should be aware that:

A) The woman's blood pressure will increase during contractions and fall back to prelabor normal between contractions.
B) Use of the Valsalva maneuver is encouraged during the second stage of labor to relieve fetal hypoxia.
C) Having the woman point her toes will reduce leg cramps.
D) The endogenous endorphins released during labor will raise the woman's pain threshold and produce sedation.
