The nurse is providing care to a postpartum patient after an emergency cesarean due to eclampsia.
The patient received spinal anesthesia before delivery.
Magnesium sulfate is infusing 2 g/hr in 100 mL of IV fluid.
Which assessment finding will cause the nurse to administer calcium gluconate to the patient via IV push?

Choice A rationale

Decreased pain level can be an effect of addressing the cause of pain, but it doesn't indicate improved uterine tone or resolution of atony.

Choice B rationale

Stable blood pressure is important, but it is not the direct outcome of improved uterine tone or the resolution of uterine atony.

Choice C rationale

A firm fundus at or below the umbilicus indicates successful contraction of the uterus, resolving uterine atony and reducing bleeding.

Choice D rationale

Reduced lochial flow can indicate decreased bleeding, but it does not directly indicate improved uterine tone or resolution of uterine atony.

Choice A rationale

Contraction duration less than 40 seconds doesn't define tachysystole. Tachysystole focuses on excessive frequency of contractions rather than their duration.

Choice B rationale

Contraction frequency of more than 5 in 10 minutes defines tachysystole. This condition indicates too frequent uterine activity, which can compromise fetal oxygenation.

Choice C rationale

Contraction intensity less than 80 mm Hg doesn't define tachysystole. Tachysystole is characterized by the number of contractions, not their intensity.

Choice D rationale

Resting tone less than 18 mm Hg is not related to the definition of tachysystole. Tachysystole concerns contraction frequency, not the resting tone of the uterus between contractions. .
