A disadvantage of internal fetal monitoring is:
An artifact on the printout is very common
Accurate information regarding FHR variability is not possible
It cannot provide data about the uterine resting tone
It is invasive and increases the risk for uterine infection
The Correct Answer is A
A. An artifact on the printout is very common. Artifacts are more common with external fetal monitoring, not internal fetal monitoring.
B. Accurate information regarding FHR variability is not possible. Internal fetal monitoring provides more accurate information about fetal heart rate (FHR) variability compared to external monitoring.
C. It cannot provide data about the uterine resting tone. Internal monitoring can measure the uterine resting tone more accurately than external methods.
D. It is invasive and increases the risk for uterine infection. Internal fetal monitoring requires inserting a device into the uterus, making it invasive and increasing the risk of infection.

Correct Answer is B
Explanation
A. Contraction lasting 85 seconds. While contractions longer than 90 seconds should be reported due to the risk of uterine hyperstimulation, an 85-second contraction is within normal limits.
B. Fetal heart rate 100/min for a 10-min period. A fetal heart rate of 100/min indicates bradycardia, which can signify fetal distress. Fetal bradycardia (below 110 beats per minute) lasting more than 10 minutes is an emergency.
C. Contraction resting period 35 seconds. A 35-second resting period between contractions is short but not abnormal enough to require immediate reporting unless accompanied by signs of fetal distress.
D. Four contractions in a 10-min period. Four contractions in 10 minutes is normal during active labor, where uterine activity is expected to increase.
Correct Answer is B
Explanation
A. Decreased maternal heart rate: Maternal heart rate usually stays the same or may increase slightly due to the physical exertion of labor, but it does not decrease as a sign of labor progression.
B. Increased intensity and frequency of contractions: The active phase of labor is characterized by more frequent and intense contractions that lead to continued cervical dilation and effacement.
C. Decreased cervical dilation: Cervical dilation increases during labor, particularly in the active phase. Decreased dilation is a sign of dysfunctional labor, not normal progress.
D. Decreased intensity and frequency of contractions: Decreasing contraction intensity and frequency would indicate a stall in labor or ineffective labor, not normal progress.
