NSG 210 Questions with Detailed
Verified Answers
Question: What is a normal fetal heart rate?
Ans: 110-160
Question: What drug is used to stimulate uterine contractions?
Ans: Oxytocin
Question: What are the desired parameters for uterine contractions?
Ans: Lasting 60 seconds or less
Not more often than 2 minutes
Question: What does Terbutaline do & what are its contraindications?
Ans: Delays delivery time, but does not stop it.
Contraindicated for gestation 34 weeks or greater & cervical dilation >6
cm.
Question: What does nifedipine do & what is a side effect to watch for?
, Page | 2
Ans: Helps suppress contractions
Watch for orthostatic hypotension
Question: When does progesterone levels start to drop?
Ans: Around 37 weeks. Was previously high because progesterone relaxes
smooth muscle of the uterus
Question: What happens to Estrogen around delivery time?
Ans: Remains high. Combination of lower progesterone and high estrogen
makes uterus more responsive to other hormones (oxytocin)
Question: What are Braxton Hick's contractions?
Ans: They are false labor contractions which are occurring due to the
decreased levels of progesterone.
Question: Explain dilation and effacement.
Ans: Dilation is the opening of the cervix to 10 cm & effacement is the
thinning of the cervical walls expressed in percentage.
Question: Where is relaxin and what does it do?
, Page | 3
Ans: Produced in the placenta
Loosens pelvic ligaments, opens pelvic outlet, causes cervical dilation
Question: What are the stages of labor & what happens in each?
Ans: Stage 1 - Cervical dilation
*cervix dilates to about 10 cm
Stage 2 - Expulsion of fetus
*starts when fetal head enters the birth canal and ends when fetus is
delivered
Stage 3- Afterbirth
*starts immediately after fetal delivery and ends with delivery of the
placenta
Stage 3 - Recovery
Question: Explain an early deceleration
Ans: Considered normal
Fetal heart rates drops and mirrors maternal contraction
caused by compression of fetal head on pelvis/soft tissue.

Question: Explain Late Decelerations
Ans: Is not normal and requires intervention
Fetal heart rate drops after maternal contraction
Caused by uteroplacental insufficiency (baby not getting enough oxygen?
Question: Explain Variable Deceleration
Ans: Not normal and requires intervention
There is not relationship between fetal heart rate drops and maternal
contraction
Caused by umbilical cord compression
Question: During Leoupold's Maneuver, you find the fetal lie to be straight up
and down. What is this called?
Ans: Longitudinal lie
Question: During Leoupold's Maneuver, you find the fetal lie to be at an
angle. What is this called?
Ans: Oblique
Question: During Leoupold's Maneuver, you find the fetal lie to be horizontal.
What is this called?
