are determination of fetal lung maturity and evaluation of the fetus’ condition when the woman has Rh isoimmunization. The most common purpose for midtrimester amniocentesis is to examine fetal cells in the amniotic fluid to identify chromosomal abnormalities. Midtrimester amniocentesis is also performed to evaluate the fetus’ condition when the woman is sensitized to Rh-positive blood, to diagnose intrauterine infection, and to investigate amniotic-fluid AFP and acetylcholinesterase when the maternal serum AFP concentration is increased.°Test-Taking Strategy: Note the strategic word, “most.” Also, noting the words "third trimester" in the question will help direct you to the option that addresses fetal lung maturity. Use of the ABCs — airway, breathing, and circulation — will also direct you to the correct option.

The nurse determines that the results are nonreactive if which finding is noted on the electronic monitoring recording strip? Absence of accelerations after fetal movement CorrectAccelerations without fetal movement with fetal heart rate (FHR) increases of 15 beats per minute for 15 secondsAcceleration of the FHR by 25 to 30 beats per minute for at least 15 seconds in response to fetal
movementTwo fetal heart accelerations within a 20-minute period, peaking at 15 beats per minute above baseline and lasting 15 seconds from baseline to baseline°Rationale: In a nonreactive (nonreassuring) stress test, the monitor recording would not demonstrate the required characteristics of a reactive (reassuring) recording within a 40-minute period. In a reactive (reassuring) recording, at least two fetal heart accelerations, with or without fetal movement detected by the woman, occur within a 20-minute period, peak at least15 beats per minute above the baseline, and last 15 seconds from baseline to baseline.°Test-Taking Strategy: Note the relationship between the word "nonreactive" in the question and “absence” in the correct option.
