A woman in her third trimester of pregnancy has been in active labor for the past 8 hours and has dilated 3 cm. The nurse's assessment findings and electronic fetal monitoring (EFM) are consistent with hypotonic dystocia, and the healthcare provider prescribes an oxytocin drip.
Which data is most important for the nurse to monitor?

Choice A rationale

Monitoring hourly blood pressure is essential, but it is not the most crucial data in this scenario. Blood pressure monitoring can help identify maternal hypotension or hypertension, which can affect uteroplacental blood flow. However, hypotonic dystocia requires monitoring contractions to assess labor progression and effectiveness of oxytocin.

Choice B rationale

Preparing for an emergency cesarean birth is a potential intervention if labor does not progress or if fetal distress occurs. However, it is not the primary data to monitor initially. The decision for a cesarean is based on a comprehensive assessment, including fetal heart rate patterns and contraction quality.

Choice C rationale

Checking the perineum for bulging may indicate imminent delivery or fetal descent. However, in the context of hypotonic dystocia, the primary concern is evaluating contraction patterns to ensure the effectiveness of oxytocin in augmenting labor.

Choice D rationale

Monitoring the intensity, interval, and length of contractions is the most critical data in this case. Hypotonic dystocia involves weak, infrequent, or irregular contractions. Oxytocin is administered to strengthen and regularize contractions, so assessing their characteristics is crucial to determine the response to treatment and guide further interventions.
