Why is continuous electronic fetal monitoring generally used when oxytocin is administered?
a. Fetal chemoreceptors are stimulated.
b. The mother may become hypotensive.
c. Maternal fluid volume deficit may occur.
d. Uteroplacental exchange may be compromised.
ANS: D
The uterus may contract more firmly and the resting tone may be increased with oxytocin use. This response reduces the entrance of freshly oxygenated maternal blood into the intervillous spaces, depleting fetal oxygen reserves. Oxytocin affects the uterine muscles. Hypotension is not a common side effect of oxytocin. All laboring women are at risk for fluid volume deficit; oxytocin administration does not increase the risk.
