Explanation
(A) Controlling the rapid delivery will reduce the risk of fetal injury and perineal lacerations. (B) The nurse should always remain with a client experiencing a precipitous delivery. (C) Pushing against the perineum may cause fetal distress. (D) Crossing of legs may cause fetal distress and does not stop the delivery process.

Explanation:
(A) LOA identifies a fetus whose back is on its mother's left side, whose head is the presenting part, and whose back is toward its mother's anterior. It is easiest to auscultate fetal heart tones (FHTs) through the fetus's back. (B) The identified fetus's back is on its mother's left side, not right side. It is easiest to auscultate FHTs through the fetus's back. (C) In an LOA position, the fetus's head is presenting with the back to the left anterior side of the mother. The umbilicus is too high of a landmark for auscultating the fetus's heart rate through its back. (D) This is the correct auscultation point for a fetus in the left sacroanterior position, where the sacrum is presenting, not LOA.

(A) Human chorionic gonadotropin is the biochemical basis for pregnancy tests. It is produced by the placenta to help maintain the corpus luteum. Its levels climb rapidly following conception, peaking at about 8 weeks and then gradually decreasing to low levels after 16 weeks. (B) Estrogen does steadily rise throughout pregnancy, increasing to 30 times that of prepregnancy levels. Although estrogen levels do change during pregnancy, it is not used as the main hormone of evaluation in pregnancy tests. (C) -Fetoprotein is the major protein in the serum of theembryo. It is initially produced by the yolk sac. (D) Lecithin and sphingomyelin are two phospholipids of which fetal lung surfactant is composed. Levels are evaluated to determine fetal lung maturity.
