(Select all that apply) A nurse is performing a nonstress test (NST) for a client who is at 32 weeks of gestation and has gestational diabetes mellitus.
The nurse uses vibroacoustic stimulation to elicit fetal movement and acceleration of FHR.
What are the indications for using this method?
The fetus’s presentation does not affect the use of VAS.
VAS is not indicated for a fetus that has not moved for 40 minutes, unless the NST result is also nonreactive.
Minimal baseline FHR variability is not a sufficient indication for VAS, unless the NST result is also nonreactive.
A history of stillbirth does not affect the use of VAS.
The test result is nonreactive after 40 minutes. Vibroacoustic stimulation (VAS) is the application of a vibratory sound stimulus to the abdomen of a pregnant woman to induce fetal heart rate (FHR) accelerations. VAS is typically used during a nonstress test (NST) to elicit fetal movement and reactivity when the baseline FHR variability is minimal or the test result is nonreactive after 40 minutes. VAS can shorten the testing time and reduce the incidence of non-reactive cardiotocography.

Choice A is wrong because the fetus’s presentation does not affect the use of VAS.
Choice B is wrong because VAS is not indicated for a fetus that has not moved for 40 minutes, unless the NST result is also nonreactive.
Choice C is wrong because minimal baseline FHR variability is not a sufficient indication for VAS, unless the NST result is also nonreactive.
Choice D is wrong because a history of stillbirth does not affect the use of VAS.
