Chapter 13- Labor and Birth Process NCLEX Question | Question and Answers (A+ guide solution)

When determining the frequency of contractions, the nurse would measure which of the following? a) Start of one contraction to the start of the next contraction b) Beginning of one contraction to the end of the same contraction c) Peak of one contraction to the peak of the next contraction d) End of one contraction to the beginning of the next contraction - The correct response is A. Frequency is measured from the start of one contraction to the start of the next contraction. The duration of a contraction is measured from the beginning of one contraction to the end of that same contraction. The intensity of two contractions is measured by comparing the peak of one contraction with the peak of the next contraction. The resting interval is measured from the end of one contraction to the beginning of the next contraction. Which fetal lie is most conducive to a spontaneous vaginal birth? a) Transverse b) Longitudinal c) Perpendicular d) Oblique - The correct response is B. A longitudinal lie places the fetus in a vertical position, which would be the most conducive for a spontaneous vaginal birth. A transverse lie does not allow for a vaginal birth because the fetus is lying perpendicular to the maternal spine. A perpendicular lie describes the transverse lie, which would not be conducive for a spontaneous birth. An oblique lie would not allow for a spontaneous vaginal birth because the fetus would not fit through the maternal pelvis in this sidelying position. Which of the following observations would suggest that placental separation is occurring? a) Uterus stops contracting altogether. b) Umbilical cord pulsations stop. c) Uterine shape changes to globular. d) Maternal blood pressure drops. - The correct response is C. After the placenta separates from the uterine wall, the shape of the uterus changes from discoid to globular. The uterus continues to contract
