300 cals; 3 cups FHR can be auscultated by Doppler at ____ wks gestation - ANS-10 to 12 weeks Describe schedule of prenatal visits for low -risk preg woman - ANS--Once every 4 wks until 28 wks -Every 2 wks from 28 to 36 wks -Once per wk until delivery In some states, screening for neural tube defects by testing either _____ or _____ is mandated by state law. This screening test is highly associated w/ both false positives & false negatives - ANS-maternal serum alphafetoprotein (A FP) or amniotic fluid AFP levels When amniocentesis is done early in preg, bladder must be ____ vs done late bladder must be _____ - ANS-*Early in preg:* bladder must be full to help support the uterus & help push uterus up into abd for easy access *Late in preg:* bladder must be empty to avoid puncture Early decels, caused by _____ & ______, usually occur _____& ______ - ANS-Caused by head compression & fetal descent Usually occur btw 4 and 7 cm & in 2nd stage of labor ---check for labor progress i f early decels are noted If cord prolapse is detected, what should examiner do? - ANS-Position mother knee -to-
chest (or l lateral) to relieve pressure on cord OR Push the presenting part off the cord until immediate c/s can be accomplished Late decels in dicate ___ & are associated w/ what conditions? - ANS-*indicate UPI* -associated w/ conditions such as: *post maturity, preeclampsia, diabetes mellitus, cardiac disease, & abruptio placentae* When decels patterns (late or variable) are associated w/ decre ased or absent variability & tachycardia, the situation is _____ & requires what? - ANS-Situation is ominous (potentially disastrous) & requires immediate intervention & fetal assessment A decrease in uteroplacental perfusion results from ____. Cord compr ession results from _____. Nursing interventions include? - ANS--*⬇ uteroplacental perfusion = late decels* (uniform shape, return to baseline after contraction, depth doesn't indicate severity, rarely falls below 100 bpm) -*cord compression = variable dec els* (severe variable = below 70 bpm lasting longer than 30 -60 sec & slow return to baseline) ---*interventions: change positon, discontinue Pitocin, administer O2, notify HCP* Most important determinant of fetal maturity for extrauterine survival? - ANS-L/S ratio (lung maturity, lung surfactant development) 5 maternal variables associated w/ high -risk preg - ANS--age (<17 or >34)
