When does engagement occur during labor?

• A. When the fetal head rotates
• B. When the fetal heart tones are strong
• C. When the widest diameter of the presenting part descends to or below the pelvic inlet
• D. When complete dilation is reached

Answer: (C)

Engagement occurs when the widest diameter of the presenting part, typically the fetal head, descends to or below the pelvic inlet. This is a crucial stage in labor because it denotes that the fetus is positioned in the birth canal and is ready for subsequent movements that facilitate delivery. Engagement is an important indicator of the stage of labor, as it signifies that the fetal head is entering the pelvic cavity, preparing for the next phases of descent and eventual birth. Other options do not accurately define engagement. For example, while the rotation of the fetal head and the strength of fetal heart tones are important aspects of labor, they do not specifically indicate that the widest diameter of the fetal presenting part has descended to the level of the pelvic inlet. Similarly, complete dilation is a later phase in the labor process and does not coincide with the engagement phase, which occurs earlier in the labor timeline. Understanding engagement helps practitioners anticipate the progression of labor and make informed decisions during childbirth.
