NSG 210 EXAM 2025 VERIFIED QUESTIONS AND
ANSWERS GRADED A+
What is a normal fetal heart rate?
110-160
What drug is used to stimulate uterine contractions?
Oxytocin
What are the desired parameters for uterine contractions?
Lasting 60 seconds or less
Not more often than 2 minutes
What does Terbutaline do & what are its contraindications?
Delays delivery time, but does not stop it.
Contraindicated for gestation 34 weeks or greater & cervical dilation >6 cm.
,What does nifedipine do & what is a side effect to watch for?
Helps suppress contractions
Watch for orthostatic hypotension
When does progesterone levels start to drop?
Around 37 weeks. Was previously high because progesterone relaxes smooth
muscle of the uterus
What happens to Estrogen around delivery time?
Remains high. Combination of lower progesterone and high estrogen makes uterus
more responsive to other hormones (oxytocin)
What are Braxton Hick's contractions?
They are false labor contractions which are occurring due to the decreased levels of
progesterone.
Explain dilation and effacement.
Dilation is the opening of the cervix to 10 cm & effacement is the thinning of the
cervical walls expressed in percentage.
,Where is relaxin and what does it do?
Produced in the placenta
Loosens pelvic ligaments, opens pelvic outlet, causes cervical dilation
What are the stages of labor & what happens in each?
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
Explain an early deceleration
Considered normal
Fetal heart rates drops and mirrors maternal contraction
caused by compression of fetal head on pelvis/soft tissue.
Explain Late Decelerations
, Is not normal and requires intervention
Fetal heart rate drops after maternal contraction
Caused by uteroplacental insufficiency (baby not getting enough oxygen?
Explain Variable Deceleration
Not normal and requires intervention
There is not relationship between fetal heart rate drops and maternal contraction
Caused by umbilical cord compression
During Leoupold's Maneuver, you find the fetal lie to be straight up and down.
What is this called?
Longitudinal lie
During Leoupold's Maneuver, you find the fetal lie to be at an angle. What is this
called?
Oblique
During Leoupold's Maneuver, you find the fetal lie to be horizontal. What is this
called?
Transverse
