A nurse is caring for a client who is receiving oxytocin to induce labor.
The nurse should discontinue the oxytocin if which of the following occurs?
A.
Six contractions in 10 min.
B.
Contractions last 60 seconds.
C.
Moderate variability of the fetal heart rate.
D.
Nonrepetitive early decelerations.
The correct answer and Explanation is :
The correct answer is A. Six contractions in 10 minutes.
Explanation:
Oxytocin is a medication used to induce or augment labor by stimulating uterine contractions. However, careful monitoring is crucial to prevent potential complications.
Option A: Six contractions in 10 minutes — This is a key indicator for discontinuing oxytocin. Normal labor typically involves 3 to 5 contractions per 10 minutes. If the contraction frequency exceeds this range, such as reaching six or more contractions in 10 minutes, it can lead to uterine hyperstimulation. This condition can compromise fetal oxygenation and result in abnormal fetal heart rate patterns or fetal distress. To ensure both maternal and fetal safety, oxytocin should be discontinued if contractions become too frequent.
Option B: Contractions last 60 seconds — Contractions lasting up to 60 seconds are generally considered normal and within the safe range for labor induction. The duration of contractions is less concerning than their frequency and intensity.
Option C: Moderate variability of the fetal heart rate — Moderate variability in the fetal heart rate is typically a positive sign, indicating that the fetus is well-oxygenated and its autonomic nervous system is functioning well. This is generally not a reason to discontinue oxytocin unless other complications arise.
Option D: Nonrepetitive early decelerations — Early decelerations are usually associated with fetal head compression and are often considered benign, especially if they are not recurrent or severe. They do not necessarily require discontinuation of oxytocin unless they are part of a pattern indicating fetal distress.
In summary, the primary concern with oxytocin administration is the risk of uterine hyperstimulation, which can be identified by excessive contraction frequency. Therefore, option A is the correct choice for when to discontinue oxytocin.
