Vibroacoustic stimulation is often used to stimulate fetal activity if the initial NST result is nonreactive and thus hopefully shortens the time required to complete the test (Greenberg, Druzin, and Gabbe, 2012). A nonreactive test requires further evaluation. The testing period is often extended, usually for an additional 20 minutes, with the expectation that the fetal sleep state will change and the test will become reactive. Care providers sometimes suggest that the woman drink orange juice or be given glucose to increase her blood sugar level and thereby stimulate fetal movements. Although this practice is common, there is no evidence that it increases fetal activity (Greenberg, Druzin, and Gabbe, 2012). A needle biopsy is not part of a NST. The FHR is recorded with a Doppler transducer, and a tocodynamometer is applied to detect uterine contractions or fetal movements. The tracing is observed for signs of fetal activity and a concurrent acceleration of FHR. Which physiological parameters does the nurse check in the ultrasound report to assess fetal well being?Assessment of physiologic parameters such as AFV, FBMs, and limb and head movements of the fetus by ultrasonography gives a reliable picture of fetal well-being. Abnormalities in the amniotic fluid volume are frequently associated with fetal disorders.
Which of the following are variables that are assessed by ultrasound scanning in the biophysical profile examination?Ultrasound evaluation.
During the biophysical profile, your provider is looking at 5 main areas to check your baby's health: body movements, muscle tone, breathing movements, amniotic fluid, and heartbeat. Each of these 5 areas is given a score of either 0 (abnormal) or 2 (normal).
Which of the following tests for fetal well being and maturity is tested for the presence of neural tube defects quizlet?The presence of alpha-fetoprotein (AFP) in the amniotic fluid indicates a neural tube defect in the fetus. The nurse needs to assess AFP levels in the amniotic fluid to determine whether the fetus has an open neural tube defect.
When does the nurse refer the pregnant patient for ultrasonography to detect maternal abnormalities that could affect the fetus?Second trimester ultrasonography should be offered to all patients, between 18 and 22 weeks' gestation, for the detection of fetal structural abnormalities.
