NST

is considered reactive if 2 accelerations in 20 minutes
OR
3 accelarations in 10 min.

*have seen both in questions being right....so very confused??

---ALSO

decreased fetal movements
1st is NST---if nonreactive 2nd is Vibroacoustic stimulation---if no response 3rd is CST or BPP??

what's the 3rd?

Both Kaplan Notes and Blueprints Ob-Gyn (2007 edition) say 2 accelerations in 20 min. If both are offered as options I would go with 2 in 20 min because this is the minimum requirement. If 2 in 20 min is not an option then go with something similar (if you have 3 accelerations in 10 min you definitely have 2 in 20 min) but if you have 1 acceleration in 10 min you may or may not have another one in the next 10 min, so this would be a bad choice.

The thing with 3 in 10 min is a requirement for the CST; in order to asses for decelerations you have to have 3 contractions present spontaneously in 10 min.

BPP, because you already have determined the NST, which is one compenent of BPP. CST is expensive and time-consuming.
