NURS 450 QUIZ 1 EXAM 2026 PREMIUM
REVIEW SET WITH DETAILED ANSWER KEY
◉Biophysical profile. Answer: -non-stress test plus ultrasound
assessment for 30 minutes
-assess 5 areas of fetal health
1.Fetal heart rate
2. Fetal breathing movements
3. Fetal body movements
4. Fetal muscle tone
5. Amount of amniotic fluid
-2 points for normal, 0 for abnormal
-done after 32 weeks
-8-10: normal results, repeat BPP weekly
-6: suspect lack of adequate oxygen, repeat BPP in 24 hours and
deliver if results are less than 6
-4: suspect lack of adequate oxygen, if less than 36 weeks deliver, if
more than 36 weeks conduct lung maturity test
-0-2: deliver ASAP
◉contraction stress test. Answer: -Assesses fetal tolerance of stress
(uterine contractions)
,-advised if non-stress test is abnormal
-Monitor fetal heart rate response to contractions started by IV
pitocin or nipple stimulation
-Try to get 3 uterine contractions within a 10 minute period
-Negative (normal) result: adequate contraction, no concerning rate
changes with contractions (No late deceleration)
-Positive: repetitive persistent late decelerations, decelerations with
more than half of contractions, not due to uterine hyperstimulation
◉4 stages of labor. Answer: 1. Contractions and dilation
-Early phase: onset of uterine contraction, 0-3 cm dilation
-Active phase: contractions become more frequent, longer, and
stronger, 4-7 cm
-Transition phase: most intense phase, 8-10 cm
2.Pushing and delivery
3. delivery of placenta
-within 30 minutes
- longer time- increased risk of hemorrhage
4. initial postpartum recovery (2 hours)
◉Rupture of membranes. Answer: -"water breaks"
-SROM: spontaneous
-AROM-artificial
, -PROM-premature
-ROM assessed by speculum exam, fern test, or Nitrazine test
◉Cervical dilation. Answer: -0-10 cm
-Vaginal exam
-Early phase: gradual change- can take hours or days
-Active phase: 1 cm/hour
-wide variation of normal progress
◉Cervical effacement. Answer: -thinning from 0 to 100 percent
-vaginal exam
◉Fetal station. Answer: -0 station-engaged
- +/- is above or below the ischial spines of pelvis
◉Uterine contractions. Answer: -measured by frequency, intensity,
and duration
-Assessed by palpation, electronic fetal monitoring, and patient
perception
◉How are first labors different than later labors?. Answer:
