There are four clients in active labor in the labor suite.Which of the clients should the nurse monitor carefully for a potential uterine rupture?

Choice A rationale

Contraction duration less than 40 seconds doesn't define tachysystole. Tachysystole focuses on frequency, not duration, of contractions over a specific time frame.

Choice B rationale

Contraction frequency of more than 5 in 10 minutes defines tachysystole. This frequency indicates excessive uterine activity, requiring intervention to prevent fetal distress.

Choice C rationale

Contraction intensity less than 80 mm Hg does not define tachysystole. Intensity relates to contraction strength, but tachysystole is about frequency exceeding the normal range.

Choice D rationale

Resting tone less than 18 mm Hg isn't part of tachysystole's definition. Tachysystole pertains to contraction frequency, not resting tone, which measures uterine relaxation between contractions.

Choice A rationale

Pumping up the vacuum manually to the pressure indicated on the pump is a standard procedure but doesn't directly minimize liability.

Choice B rationale

Recognizing cup detachment (pop off) as a warning sign is critical, as it indicates excessive force or poor positioning, which can lead to fetal or maternal injury.

Choice C rationale

Limiting the cup's attachment to the fetal head to 5 to 10 minutes reduces the risk of scalp injury and other complications, thus minimizing liability.

Choice D rationale

Timing the procedure from insertion of the cup into the vagina until the birth is a guideline but doesn't specifically address liability concerns.

Choice E rationale

Releasing pressure between contractions prevents continuous suction on the fetal head, reducing the risk of injury and thereby minimizing liability.
