A client is admitted to the labor unit. On vaginal examination, the presenting part in a cephalic presentation was at station plus two. Station 12 means that the:
A. Presenting part is 2 cm above the level of the ischial spines
B. Biparietal diameter is at the level of the ischial spines
C. Presenting part is 2 cm below the level of the ischial spines
D. Biparietal diameter is 5 cm above the ischial spines
Correct Answer: C
Explanation/Reference:
Explanation:
(A) Station is the relationship of the presenting part to an imaginary line drawn between the ischial spines. If the presenting part is above the ischial spines, the station is negative. (B) When the biparietal diameter is at the level of the ischial spines, the presenting part is generally at a +4 or +5 station. (C) Station is the relationship of the presenting part to an imaginary line drawn between the ischial spines. If the presenting part is below the ischial spines, the station is positive. Thus, 2 cm below the ischial spines is the station +2. (D) When the biparietal diameter is above the ischial spines by 5 cm, the presenting part is usually engaged or at station 0.
