Non-reactive NST does not meet the acceleration criteria Non-reactive NST’s occur more often in the preterm infant under 32 wks because they are more likely not to meet the criteria due to immature ANS Meds such as Betamethasone, alcohol, beta-blockers, muscle relaxants, and CNS depressants
Multiple choice
True or False TRUE or FALSE 8. Results of the NST can be reinforced and carry more weight when amniotic fluid volume is adequate.
6. True or False Non stress tests can be facilitated by doing (VAS) Vibroaccoustic stimulation when the fetus is thought to be in a sleep mode.
Watch language with pt – tazer, buzzer, zapper VAS programmed for this time, push button til stops Decels common Do not use if fetus compromised or has heart issues
MULTIPLE CHOICE 10. The tracing above shows: a. lates and q1 min contractions b. positive CST; Non Reactive NST c. Late decelerations with hyperstimulation
Many studies, none to find side effects to fetus
Measurement of crown rump is most accurate. If LMP and crown rump measurement > 7 days, date not changed Discrepancy > 1 wk, usually due to inaccurate LMP As pregnancy progresses, measurements not as accurate for dating as genetic and other factors
Decreased flow to cerebral artery can indicate anemia or hypoxemia
