Included in the definition of tachysystole is:
Contraction duration of less than 40 seconds.
Contraction frequency of greater than 5 in 10 minutes.
Contraction intensity of less than 80 mm Hg.
Resting tone of less than 18 mm Hg.
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice A rationale
Magnesium sulfate is not given to increase diuresis; this is not its primary effect and is incorrect in the context of treating preeclampsia.
Choice B rationale
Magnesium sulfate is administered to prevent seizures in patients with preeclampsia. It acts as a central nervous system depressant and helps in preventing eclampsia.
Choice C rationale
Although magnesium sulfate may have a mild effect on reducing blood pressure due to its vasodilatory properties, this is not its primary purpose in the management of preeclampsia.
Choice D rationale
Magnesium sulfate is not used to slow the process of labor; its main role is seizure prophylaxis in preeclampsia.
Correct Answer is C
Explanation
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.
