Q

During labor, the nurse is aware that the woman’s vital signs are best assessed between contractions. What is the rationale for this?

A

The contractions ⬇ blood flow to the placenta, therefore increasing the woman’s blood volume and altering her vital signs. ( BP will ⬆ and Pulse RAte will ⬇).

Q

Why should continuous electronic fetal monitoring be used when oxytocin is administered?

A

Because utero placental exchange may be compromised. The uterus may contract more firmly, and the resting tone may be increased with oxytocin use. This ⬇ entrance of freshly oxygenated maternal blood into the intervillous spaces, depleting fetal O2 reserves.
