NURS 315 Final Exam: Questions & Solutions (Pass!)
Electronic fetal monitoring Right Ans - - Obtain continuous FHR for
observation and evaluation of fetus
- Monitor for variability of HR, contractions, accelerations, decelerations
Uterine contractions Right Ans - Frequency, duration, intensity (TOCO-
must assess patient/palpate; or IUPC)
Normal uterine activity Right Ans - Less than 5 contractions in 10 min
averaged over 30 min
Tachysystole uterine activity Right Ans - Greater than 5 contractions in 10
min averaged over 30 min
Uterine contractions interpretation (cont.) Right Ans - Frequency, duration,
intensity, and relaxation time between contractions are also measured
Baseline Right Ans - Normal (110-160), tachy (> 160), brady (< 110)
Variability Right Ans - Absent (none), minimal (0-5), moderate (6-25),
marked (> 25)
Accelerations Right Ans - 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 Right Ans - Occur with more than 50% of uterine
contractions over a 20 minute period
Intermittent decelerations Right Ans - Occur with less than 50% of uterine
contractions within a 20-minute period.
Episodic decelerations Right Ans - No association with contractions
Periodic decelerations Right Ans - Associated with contractions (early, late,
variable)
, Early decelerations Right Ans - Nadir appears at peak of contraction, head
compression
Late decelerations Right Ans - Nadir occurs after acme of contraction,
utero-placental insufficiency
Variable decelerations Right Ans - - Shaped like a U, V, or W
- Vary in duration, nadir, and timing
- Due to cord compression
VEAL CHOP Right Ans - V- Variable
E- Early Decels
A- Accelerations
L-Late Decels
C- Cord Compression
H- Head Compression
O - OK
P - Placenta
Category I Right Ans - - Everything WNL
- Strongly predictive of normal fetal-acid base status at time observed
- Follow routinely, no action needed
Category II Right Ans - - 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 Right Ans - Absent baseline variability and any of the
following: recurrent late decelerations, recurrent variable decelerations,
bradycardia, sinusoidal pattern
Interventions for Cat III Right Ans - Maternal O2, change of position,
discontinue labor stimulation (Pitocin), treat maternal hypotension
Amniocentesis Right Ans - - Detects genetic, metabolic, and DNA
abnormalities
- Can detect neural tube defects
- Amniotic fluid obtained through needle aspiration
