The 5 factors that affect and define the labor and birth process are:

A. Create a warm relaxing environment: A warm and relaxing environment can help reduce stress and anxiety, contributing to pain relief during labor.

B. Administering sacral counterpressure: Sacral counterpressure, where pressure is applied to the lower back, is a non-pharmacological method used to relieve labor pain, particularly during back labor.

C. Epidural injection: An epidural injection is a pharmacological pain management technique, as it involves the administration of anesthetic drugs.

D. Effleurage: Effleurage is a light, circular massage technique that helps distract the mother from contraction pain, making it a non-pharmacological pain relief method.

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.
