A vaginal examination on a laboring client reveals that the biparietal diameter of the fetal head is at +2 station. This indicates that the fetal head is
a. achieving attitude c. below the ischial spines
b. reaching ballottement d. floating above "0" station
C
Station describes the fetal positioning in the maternal pelvis and is described using 0 as at the level of the ischial spines with minus numbers above the ischial spines and plus numbers below the level of the ischial spines. Achieving attitude does not reflect station. Reaching ballottement refers to the first maneuver of Leopold's maneuvers used to determine fetal presentation and position. Floating above "0" station would be described as not engaged, or being above the level of the ischial spines.
