NURS 315 Final Exam Questions With
Solutions
Accelerations Visual, abrupt increase in FHR (30 seconds from onset to peak), peak must
be 15 bpm and last at least 15 secs, acceleration > 10 min = change in baseline
Recurrent decelerations Occur with more than 50% of uterine contractions over a 20
minute period
Intermittent decelerations Occur with less than 50% of uterine contractions within a 20-
minute period.
Episodic decelerations No association with contractions
Periodic decelerations Associated with contractions (early, late, variable)
Early decelerations Nadir appears at peak of contraction, head compression
Late decelerations Nadir occurs after acme of contraction, utero-placental insufficiency
, NURS 315 Final Exam Questions With
Solutions
Variable decelerations - Shaped like a U, V, or W
- Vary in duration, nadir, and timing
- Due to cord compression
VEAL CHOP V- Variable
E- Early Decels
A- Accelerations
L-Late Decels
C- Cord Compression
H- Head Compression
O - OK
P - Placenta
Category I - Everything WNL
- Strongly predictive of normal fetal-acid base status at time observed
- Follow routinely, no action needed
, NURS 315 Final Exam Questions With
Solutions
Category II - May include some abnormal findings
- Does not predict abnormal fetal acid-base status, but requires evaluation, continued
surveillance, and re-evaluation within the context of the clinical situation
Category III Absent baseline variability and any of the following: recurrent late
decelerations, recurrent variable decelerations, bradycardia, sinusoidal pattern
Interventions for Cat III Maternal O2, change of position, discontinue labor stimulation
(Pitocin), treat maternal hypotension
Amniocentesis - Detects genetic, metabolic, and DNA abnormalities
- Can detect neural tube defects
- Amniotic fluid obtained through needle aspiration
Amniocentesis complications Vaginal spotting and cramping, mild fluid leaking
Chorionic villus sampling (CVS) - Used to detect genetic, metabolic, and DNA
abnormalities
