The doctor informed the woman that she is on station -1. Mrs. Dela Cruz asked the nurse, what does a station -1 means, the most appropriate response of the nurse is:
a. “It means that engagement has already occurred.”
b. “The presenting part of your baby is at the entrance of the true pelvis or the largest diameter of the presenting part into the true pelvis.”
c. “Your baby is still floating or “ballotable”
d. “The presenting part of your baby is at the vulvar ring of your reproductive organ.”
Answer: C.
Station -1 means that the fetal presenting part is above the level of the ischial spines. Letter A is wrong because engagement is described as Station 0. Letter B is incorrect because the statement of nurse is describing the occurrence of engagement that is again station 0. Prior to engagement the fetus is said to be "floating" or ballottable, thus letter C is the best option. Letter D, is describing crowning which is described as Station +3 or +4.
