A woman who is in her third trimester and is at risk for preterm birth calls the clinic to get the results of her fetal fibronectin test (fFN). The nurse sees the result is negative. Which advice to the patient is most appropriate?
A.
Come to the perinatal clinic for a screening ultrasound.
B.
Continue the current management plan as directed.
C.
Go to the hospital immediately for imminent delivery.
D.
Plan to continue taking betamethasone (Celestone) for 1 week.
ANS: B
A negative fFN test indicates that the chance of a woman giving birth in the next week is approximately 1%, so she should continue her management plan already in place. There is no need for a screening ultrasound or hospitalization. Betamethasone is a corticosteroid shown to improve outcomes in premature birth. Because this woman is at low risk of delivery within the next week, betamethasone is not indicated.
