The most common cause of decreased variability of the fetal heart rate (FHR) lasting 30 minutes or less is:
 
  1. altered cerebral blood flow.
  2. fetal hypoxemia.
  3. umbilical cord compression.
  4. fetal sleep cycles.

Question 2

In recent trends in childbirth practice:
 
  1. delayed pushing is discouraged in the second stage of labor.
  2. rates of episiotomies are increasing.
  3. midwives perform more episiotomies than physicians.
  4. newborn infants remain with the mother and are encouraged to breastfeed.

Answer to Question 1

4
1. Incorrect. Altered fetal cerebral blood flow results in early decelerations in the FHR.
2. Incorrect. Fetal hypoxemia would be evident by tachycardia initially then bradycardia. There may be a persistent decrease or loss of FHR variability.
3. Incorrect. Umbilical cord compression results in variable decelerations of the FHR.
4. Correct. A temporary decrease in variability can occur when the fetus is in a sleep state. These sleep states do not usually last longer than 30 minutes.

Answer to Question 2

4
1. Incorrect. Delayed pushing is encouraged for several reasons.
2. Incorrect. The rates of episiotomies are declining.
3. Incorrect. Midwives perform fewer episiotomies than doctors do.
4. Correct. Breastfeeding is encouraged for newborns immediately after birth.
