The contraction stress test (CST):
 
  1. sometimes employs vibroacoustic stimulation.
  2. is an invasive test however contractions are stimulated.
  3. is considered negative if no late decelerations are observed with the contractions.
  4. is more effective than NST if membranes have already been ruptured.

Question 2

The volume of amniotic fluid is an important factor in assessing fetal well-being. Oligohydramnios (having less than 300 ml of amniotic fluid) is associated with which kind of fetal anomaly?
 
  1. Renal
  2. Cardiac
  3. Gastrointestinal
  4. Neurologic

Answer to Question 1

3
1. Incorrect. Vibroacoustic stimulation is sometimes used with NST.
2. Incorrect. CST is invasive if stimulation is by IV oxytocin but not if by nipple stimulation.
3. Correct. No late decelerations is good news.
4. Incorrect. CST is contraindicated if membranes have ruptured.

Answer to Question 2

1
1. Correct. Having less than 300 ml of amniotic fluid (oligohydramnios) is associated with fetal renal anomalies.
2. Incorrect. The fetal cardiovascular system has no bearing on amniotic fluid.
3. Incorrect. Gastrointestinal anomalies are associated with hydramnios or having more than 2 L of amniotic fluid.
4. Incorrect. The fetal neurologic system has no bearing on amniotic fluid.
