Select the one best answer to each question (unless otherwise instructed).
An abnormal contraction stress test result means that within a 10-minute period
A. One uterine contraction occurred.
B. Oxytocin level decreased to an acceptable range.
C. Recurrent early decelerations of fetal heart rate occurred.
D. Recurrent late decelerations of fetal heart rate occurred.
All of the following elements are part of a biophysical profile except
A. Contraction stress test
B. Amniotic fluid volume estimation
C. Fetal muscle tone assessment
D. Fetal respiration evaluation
For which of the following pregnant women would a nonstress test be indicated?
A. A healthy woman with her third pregnancy at 37 weeks of gestation
B. A pregnant woman with diabetes mellitus
C. A pregnant woman with a previous preterm delivery
D. A pregnant woman with an ultrasonographic (US) finding that the fetus is large for gestational age
A pregnant woman has been recording fetal activity. She reports that her fetus has moved much less often than usual that day. You check the fetal heart rate and find it is 136 beats/ min. What else should be done that day?
A. Reassure her that it is normal for a fetus to have "sleepy" days.
B. Ask her to continue to chart fetal activity .
C. Perform a nonstress test the same day.
D. Recommend induction of labor.
The contraction stress test is used to assess
A. Maturity of the fetus
B. Size of the fetus
C. Gestational age of the fetus
D. Well-being of the fetus
All these statements about biophysical profile testing are accurate except
A. Scores of 4 or lower indicate fetal compromise and usually necessitate immedi ate delivery.
B. When used to evaluate high-risk pregnancies, it is usually appropriate to start at or after 32 weeks of gestation.
C. Scores of 8 and higher indicate fetal compromise and usually require immediate delivery.
D. It includes nonstress testing and US evaluation.
Fetal heart rate response to auditory stimulation may be used as an indication of fetal well-being.
True
False
A contraction stress test can be done only after the membranes have ruptured.
True
False
Turning a woman on her side may correct an abnormal fetal heart rate pattern.
True
False
Variable fetal heart rate decelerations are probably due to compression of the umbilical cord.
True
False
Early fetal heart rate decelerations are usually not associated with fetal compromise.
True
False
An abnormal nonstress test result should be followed by a contraction stress test or biophysical profile.
True
False
A normal nonstress test result occurs when there are no fetal heart rate accelerations with fetal activity.
True
False
Fetal bradycardia is a baseline heart rate less than 110 beats/min.
True
False
Fetal heart rate accelerations during a scalp stimulation test indicate the fetus is acidotic.
True
False
In which of the following situations is internal fetal monitoring contraindicated?
A. Twins
B. Placenta previa
C. Post-term pregnancy
D. Vaginal birth after cesarean delivery
Fetal tachycardia, without accompanying decelerations, may be caused by
A. Narcotics given to the laboring woman
B. Fetal hypothyroidism
C. Maternal fever
D. Post-term fetus
Loss of fetal heart rate variability may be caused by all of the following factors except
A. Fetal activity
B. Barbiturates or tranquilizers given to the mother
C. Fetal acidosis
D. Chronic fetal hypoxia
In which of these situations would fetal activity determinations be most helpful?
A. Contracted maternal pelvis
B. First trimester Rubella infection
C. Previous macrosomic baby (>4,000 g [>8 lb 13 oz])
D. A pregnant woman with chronic hypertension
