The fetus of a patient in labor is in a vertex presentation and at a –1 station. How should the nurse interpret the location of the fetal head?
A) Floating
B) Engaged
C) Crowning
D) At the ischial spines
A
Feedback:
Engagement refers to the settling of the presenting part of a fetus far enough into the pelvis that it rests at the level of the ischial spines, the midpoint of the pelvis. The degree of engagement is established by vaginal and cervical examination. Station refers to the relationship of the presenting part of the fetus to the level of the ischial spines. If the presenting part is above the spines, the distance is measured and described as minus stations, such as –1 . The fetal head is currently floating. The head would be engaged if it were at the level of the ischial spines. Crowning is when the top of the fetal head is visible and birth is imminent.
