RNC-OB Exam Prep (Pt 2) Without Patho 2024-2025
EFM HR Baseline Criteria - Answer At least 2 minutes in a 10-minute strip
The onset of deceleration to nadir is less than 30 seconds. - Answer Variable
Gradual decrease in FHR with onset of deceleration to nadir greater than or equal to 30
seconds. - Answer Late deceleration
Tachysystole - Answer More than five uterine contractions in 10 minutes, averaged over
a 30-minute window; Rest Time is less than one minute between contractions.
SBAR stands for - Answer S: Situation
B: Background
A: Assessment (what you think is going on)
R: Recommendation (say what you think should happen, ask for orders, etc)
Fetal pH changes during the latent phase - Answer latent phase has minimal effect on
base deficit.
Changes in fetal pH during the active first stage-Answer the mean base deficit increases
by about 1 mmol/every 3 hours, due to an increase in the frequency and in CTX
Changes in fetal pH during the second stage-Answer with increase in both strengths
and frequency and the additional pushing effort, base deficit will increase by 1mmol/L
every 1 hour.
Precipitous Delivery - Answer birth of the fetus after less than 3 hours of labor
,Fundal height - Answer Measured, in cm, from top of symphysis pubis to top of fundus.
Above level of symphysis @ 12-14 weeks; at umbiicus or 20cm @ 20 weeks; rises
approx. 1cm/week until 36 weeks
Early Term - Answer 37.0-38.6 weeks gestation
Full Term - Answer 39.0-40.6
Late Term - Answer 41 weeks to 41 weeks and 6 days
Post term - Answer 42 weeks and beyond
Leopolds Maneuvers** - Answer Abdominal palpation conduction for determination of
fetal weight, lie, presentation, position and engagement should be performed prior to
placement of EFM.
If the fundal height does not appear appropriate for gestational age after use of the
Leopolds, what do you do? ** - Answer Measure from the suprapubic prominence to the
top of the fundus in centimeters.
If the uterus is shaped longitude and ovoid what does this suggest?** - Answer This
suggests a longitudinal lie.
If the uterus is shaped transverse ovoid what does this indicate?** - Answer This
indicates transverse lie
Is there a long smooth prominence to one side of the abdomen? ** - Answer This
indicates the back of the fetus.
First Maneuver of Leopold's - Answer *Determine presenting part: Palpate uterine
, fundus and feel is it hard or soft?
Soft? Fetus is Vertex, buttocks is softer and irregular than head.
Hard? Fetus is Breech, Head is harder and round. uniform.
Second Maneuver of Leopold's - Answer *Determines where fetal back is located in the
uterus.
Hold left hand steady on side of uterus while palpating opposite side of uterus with right
hand.
Locate the SMOOTH back.
Third Maneuver of Leopold's - Answer *Confirms presenting part is engaged.
Palpate suprapubic area, expect a hard rounded head.
Attempt to grasp presenting part gently between thumb and fingers.
If presenting part is NOT engaged, presenting part will FLOAT upwards.
Fourth Maneuver of Leopold's - Answer *Determines whether the head is flexed or
extended
Omit if fetus is breech.
Turn to face woman's feet; Place hands on sides of uterus with fingers pointed toward
the pelvic outlet.
On one side, slide fingers downward and feel for cephalic prominence.
If head is flexed.
Fetal Lie - Relationship of the long axis (spine) of the fetus to the long axis (spine) of the
mother
Types: Longitudinal (vertical) primary lie found in labor (cephalic or breech)
Transverse Lie: fetal spine is perpendicular to the maternal spine
Oblique lie: fetal axis at right angle diagonal to maternal axis
