NURS 330 Exam #1 Questions With Complete Solutions
3 Openings in the Fetal Heart Correct Answers Foramen Ovale
Ductus Arteriosus
Ductus Venosis
Absent Variability Correct Answers 0-2 beats of change
Undulation of heart rate not present. You don't want to see this
and you should be concerned about the baby
Acceleration Definition (<32 weeks gestation) Correct Answers
-Abrupt increase in FHR at least 10 bpm above the baseline
-Lasting at least 10 seconds
-Returning to baseline less than 2 minutes from beginning of
acceleration
Acceleration Definition (>32 weeks gestation) Correct Answers
-Abrupt increase in FHR at least 15 bpm above the baseline
-Lasting at least 15 seconds
-Returns to baseline less than 2 minutes from beginning of
acceleration
Autosomal Dominant Correct Answers -1 copy of mutation
-50% (1:2) chance
-Marfan's Syndrome
-Treacher-Collins
,-Dwarfism
Autosomal Recessive Correct Answers -2 copies of mutation
-25% (1:4) chance
-Not sex chromosome related
-Cystic Fibrosis (CF)
-Sickle Cell Anemia
Bacterial Vaginosis Correct Answers S&S: Thin, whitish-
GRAY VAGINAL DISCHARGE with FISHY ODOR
-ASSOCIATED WITH PRETERM LABOR
Tx: Flagyl
-On microscope exam, "clue cells" present which are epithelial
cells covered in bacteria so that you cannot see the actual cell
Bradycardic FHR Range Correct Answers <110 bpm
Candidiasis Correct Answers -Yeast Infection
-White creamy to curd-like vaginal discharge
-Very itchy
-Tx: OTC monostat, Rx diflucan and antifungal creams
Category 1 Correct Answers Strongly predictive of normal
fetal acid-base status at the time of observation
-Baseline FHR: 110-160 bpm
-Moderate variability (5-25 bpm)
-No late decelerations
, -No variable decelerations
-No early decelerations
-Accelerations are present or absent
Category 2 Correct Answers -Bradycardia not accompanied by
absent baseline variability
-Trachycardia
-Variability: minimal, moderate, absent but not accompanied by
recurrent decelerations
-Accelerations may be absent with stimulation
-Decelerations: recurrent, variable, or late accompanied by
minimal or moderate baseline variability
-Prolonged decelerations >2 mins but <10 mins.
Category 3 Correct Answers FHR tracing is abnormal and
predictive of abnormal fetal acid-base status. Requires prompt
intervention.
-Sinusoidal pattern (undulation very uniform)
-Absent baseline variability
-Recurrent late decelerations
-Recurrent variable decelerations
-Bradycardia
Causes of marked variability Correct Answers -Fetal activity
-Amphetamines
-Decreased uteroplacental perfusion
-Umbilical cord compression
Causes of minimal variability Correct Answers -Fetal sleep
