Question

A laboring woman's uterine contractions are being internally monitored. When evaluating the monitor tracing, which finding is a source of concern and requires further assessment?

1) Frequency every 2 1/2 to 3 minutes
2) Duration of 80 to 85 seconds
3) Intensity during a uterine contraction of 85 to 90 mm Hg
4) Average resting pressure of 20 to 25 mm Hg

Answer 1

A duration of 80 to 85 seconds for uterine contractions during labor is concerning and requires further assessment because it may sharply reduce oxygenated blood flow to the fetus, potentially leading to fetal distress.

Step-by-step explanation:

When evaluating the internal monitoring of a laboring woman's uterine contractions, the finding that raises concern and necessitates further assessment is duration of 80 to 85 seconds for each uterine contraction. Normal contractions at the end of true labor usually last for about 60 to 90 seconds. However, prolonged contractions, especially those approaching 90 seconds or more, can sharply reduce oxygenated blood flow to the fetus, potentially leading to fetal distress, and thus warrant closer monitoring or intervention. The other findings including contractions frequency every 2 1/2 to 3 minutes, contraction intensity of 85 to 90 mm Hg, and an average resting pressure of 20 to 25 mm Hg are within normal limits during active labor.
