What statement best indicates that a patient is in the second stage of labor?

The statement "I feel like I have to shit" is a classic indication that a patient is in the second stage of labor, which is the phase where the baby is moving down the birth canal and the mother feels intense pressure in the pelvic region. This sensation is often described as a strong urge to push or bear down, similar to the need to have a bowel movement. It reflects the physiological changes occurring as the baby's head descends, pressing on the rectum and pelvic floor muscles, prompting this feeling.

The other statements do not accurately describe the second stage of labor. Shaking may occur during labor but is more commonly associated with emotional stress or physiological responses; contractions that are "very far apart" indicate early labor rather than the active pushing stage; and expressing doubt about the ability to give birth is not a physical sign reflecting the second stage specifically. Therefore, the first statement is the most indicative of a patient in the second stage of labor.
