During labor a fetus with an average heart rate of 135 beats/min over a 10-minute period would be considered to have:

a. Bradycardia. c. Tachycardia.
b. A normal baseline heart rate. d. Hypoxia.

Question 2

When assessing the relative advantages and disadvantages of internal and external electronic fetal monitoring, nurses comprehend that both:

a. Can be used when membranes are intact.
b. Measure the frequency, duration, and intensity of uterine contractions.
c. May need to rely on the woman to indicate when uterine activity (UA) is occurring.
d. Can be used during the antepartum and intrapartum periods.

Answer to Question 1

ANS: B
The baseline heart rate is measured over 10 minutes; a normal range is 110 to 160 beats/min. Bradycardia is a fetal heart rate (FHR) below 110 beats/min for 10 minutes or longer. Tachycardia is an FHR over 160 beats/min for 10 minutes or longer. Hypoxia is an inadequate supply of oxygen; no indication of this condition exists with a baseline heart rate in the normal range.

Answer to Question 2

ANS: D
External monitoring can be used in both periods; internal monitoring can be used only in the intrapartum period. For internal monitoring the membranes must have ruptured, and the cervix must be sufficiently dilated. Internal monitoring measures the intensity of contractions; external monitoring cannot do this. With external monitoring, the woman may need to alert the nurse that UA is occurring; internal monitoring does not require this.
