What stage of labor ends with the physiologic stabilization of the mother?

A. Place the client in a lateral position. Hypotension is a common side effect of epidural anesthesia. Positioning the client laterally helps improve venous return and cardiac output, which can help raise blood pressure.

B. Elevate the legs. Elevating the legs can help improve circulation, but it is not the first action. The priority is to position the client laterally to improve venous return.

C. Notify the provider. While the provider should be notified, the first action is to take immediate corrective measures to address hypotension.

D. Increase IV fluid rate. Increasing IV fluids helps combat hypotension, but it is secondary to positioning the client laterally to improve blood flow.

A. Presentation, latent phase, powers, position and attitude. While "presentation," "powers," and "position" are relevant, the "latent phase" is a stage of labor, not a factor that affects the labor process. "Attitude" refers to the fetal posture but does not cover the entire process.

B. Passenger, passageway, powers, position and psychological response: These five factors are key components that affect labor and birth: Passenger: The fetus and placenta. Passageway: The birth canal. Powers: The contractions. Position: The mother’s position during labor. Psychological response: The mother’s emotional state during labor.

C. Passenger, presentation, lie, attitude and station: These terms describe aspects of the fetus's position and movement, but they do not encompass all the factors affecting labor.

D. Passageway, presentation, powers, contractions and position: This is close, but "psychological response" is missing, which is one of the essential components affecting labor.
