NUR 353 Exam 1 Practice Questions and
Complete Solutions
Reproduction ✅the total process by which organisms produce offspring from
fertilization to birth
Populations at greatest risk for problems with reproduction ✅impoverished populations
and adolescent
Where in the female anatomy, does fertilization typically occur? ✅ampulla of fallopian
tube
Which phrase best describes where the female urethral opening is located? ✅between
the clitoris and the vaginal opening
Linea negra ✅a pigmented line extending from the symphysis pubis to the top of the
fundus
Approximated increase in blood volume during pregnancy, above nonpregnancy levels
✅1500 ml or 40-50%
Viability ✅the capacity to live outside of the uterus
Quickening ✅first recognition of fetal movements by the mother
Chadwick sign ✅increased vascularity in the vaginal mucosa and cervix which result in
violet-bluish color
Conception ✅formation of a viable zygote, union of a single egg and sperm, rare two
sperm hit egg the same time and normally those pregnancies do not continue. Different
sexes cant be identical
Fertilization ✅the union of a spermatozoal nucleus with an egg nucleus to form the
primary nucleus of am embryo
Gametogenesis ✅the formation and development of germ cells, oocytes, and
spermacytes
Gestation ✅the period of development in the uterus from conception until birth
Contraception ✅a process that interferes with the normal process of ovulation,
fertilization, and implantation
, Frequency ✅contraction frequency overall generally ranges from 2-5 per 10 min during
labor, w/ lower frequencies seen in first stage of labor and higher frequencies ( up to 5
contractions in 10 min) seen during second stage of labor
Duration ✅contraction duration remains fairly stable throughout first and second
stages, ranging from 45-80 seconds not generally exceeding 90 seconds
Strength ✅uterine contractions generally range from peaking at 40-70 mm hg in first
stage of labor to over 80 mm hg in second stage. Contractions palpated as "mild" would
likely peak at less than 50 mm hg if measured internally, whereas contractions palpated
as "moderate" or greater would likely peak at 50 mm hg or greater if measured internally
Resting tone ✅average resting tone during labor is 10 mm hg; if usig palpation, should
palpate as "soft"
Relaxation time ✅relaxation time is commonly 60 seconds or more in first stage and
45 seconds or more in second stage
Montevideo units (mvus) ✅mvus usually range from 100-250 in first stage; may rise to
300-400 in the second stage. Contraction intensities of 40 mm hg or more and mvus of
80-120 are generally sufficient to initiate spontaneous labor. Mvus are used only w/
internal monitoring of contractions
Intermittent auscultation ✅involves listening to fetal heart sounds at periodic intervals
to assess the fhr
Purpose of electronic fetal monitoring (efm) ✅ongoing assessment of fetal oxygenation
Tocotransducer (toco) is placed ✅superior to the umbilicus,
Ultrasound transducer (fhr) is placed ✅inferior to the umbilicus
What controls fetal heart rhythm ✅intrinsic rhythmicity of the fetal heart, the cns, and
fetal autonomic nervous system
Increase in sympathetic response results in ✅acceleration of the fhr
Increase in parasympathetic response produces a ✅slowing of the fhr
Baseline fhr ✅the average rate during a 10 min segment that excludes periodic or
episodic changes, periods of marked variability, and segments of the baseline that differ
by more than 25 beats/mi
